Seed Saving: It’s A Good Thing

Though it is not quite time yet for “autumn leaves to drift by my window,” it is getting to be time for gardeners to start thinking about saving seeds from their favorite plants and flowers.  Dr. Tom Wilten, when he taught the Dallas County Master Gardener class on propagation, developed a list of ten reasons why someone might want to propagate plants from seeds and cuttings.   Some of these reasons included to save money, produce a genetically identical plant from cuttings, etc.  However, for some gardeners, it just seems inherently “right” to connect with the entire life cycle of a plant.

Seed Saving, Dallas Garden Buzz

Here we are connecting with the entire life cycle of the plant, in our kitchen, saving seeds.

When thinking about saving seeds, there are several factors that one should consider.  It is important to remember that not all seeds can be legally, or should be, saved.  According to Willaim Woys Weaver, author of Heirloom Vegetable Gardening,  there are basically three different kinds of seeds.  Only one of these three kinds of seeds can, or should, be saved:

1) Genetically modified seeds (GM seeds):  These are seeds that have been artificially changed to make them resistant to pathogens and/or herbicides.  No matter what you may philosophically or medically think about the use and consumption of plants grown from GM seeds, it is against the law to save GM seeds since they are patented.  One cannot legally save seeds from or reproduce a GM patented plant unless you pay the maker a royalty.  In general, the average homeowner does not have to worry about this as currently GM seeds are used by huge commercial growers who grow monocultures, such as corn, soybeans, etc.  However, if growing a patented plant, just be aware of this.

2)  F1 Hybrid seeds:  This is another type of patented seed that is a cross between different plant species.  F1 refers to Filial 1:  the first filial generation of seeds/plants resulting from a cross mating of distinctly different parental types. These are commonly found in seed catalogues and purchased by homeowners.  One should not however save seeds from F1 hybrid plants because they will not grow true to type, plus after a few generations F1 hybrid plants will eventually lose the traits for which they were bred.  Most plants and seed packets are prominently labeled if they are F! Hybrid seeds or plants.

3)  Open-pollinated seed:  Open-pollinated plants are those plants that are pollinated by nature which may be bees, wind, birds, etc.  Seeds from these open-pollinated plants have often been passed down from generation to generation (heirloom seeds) though they may be more recently developed.

To save seed from open-pollinated plants there are several things to consider.  First, the seed must be fully ripe/developed.  This may seem obvious, but for some plants such as cucumbers, it means that the fruit must be left on the vine until it turns yellow, and gourds, beans and peas must be left on the vine until the seeds rattle in their hardened shells.

The second thing to remember is that because open-pollinated seeds are pollinated by nature, it is very easy to get cross pollination since bees fly from flower to flower and the wind may carry pollen across a yard or field.  Basil and mint are notorious for being “promiscuous” with different varieties easily cross pollinating.  Therefore, if you are saving basil seed you should not save seed from, for example, a lime basil planted too close to a sweet basil.  Seed from this cross may, or most likely may not, be good tasting.

Finally, when storing seeds it is important to let them dry thoroughly, and then store them in a cool, dry place.  If kept properly, most seeds will be viable for several years.

Do you have a favorite plant from which you save seeds?  Let us know, and tell us your technique for saving them.  Not just pass-a-long plants but pass-a-long knowledge is, as Martha Stewart would say, “a good thing.”

What Would We Do Without Turk’s Cap?

All gardeners have those tough spots where nothing seems to want to grow.  Dry shade? Morning shade followed by hot west sun? Neglected, hard to water spots? It’s enough to bring on a tension headache.

The bright apple green leaves and red furled blooms of Turk’s cap Malvaviscus arboreus var. drummondii are often just the right solution.  I love easy to grow plants, but this Texas native is almost beyond belief.  Shade, sun, or a little of both? Moist or just on rainfall alone?  Clay, loam, sand, or limestone soils (with good drainage)?  Insect damage? Very minimal. All North Texas gardeners have to do is cut the stems back to the ground after a hard freeze in the fall.

The blooms on Turk’s cap are so unusual.  The vermillion red flowers are twisted into a loose tube of overlapping petals, with a red stamen protruding from the center.  The flowers are said to resemble a Turkish turban, thus the name, Turk’s cap.  Butterflies and hummingbirds are drawn to the blooms.  The marble-sized fruit is edible and is enjoyed by a number of birds and animals.

Red Turk's Cap, Dallas Garden Buzz

At the Demonstration Garden, we have enjoyed a Turk’s cap with pink blooms for many years.  I hope it is the Greg Grant introduction, named after the first woman horticulture student at Texas A&M, Pam Puryear.  Her namesake has been designated a Texas Superstar by the AgriLife Extension Service.

Pink Turk's Cap

Pink Turk’s Cap

The variety name for Turk’s cap, Malvaviscus arboreus var. drummondii,  honors another groundbreaking botanist in Texas.  Thomas Drummond was a Scottish naturalist, born in Scotland about 1790.  In 1830, he came to America to collect plant specimens from the western and southern United States.  He arrived in Velasco, Texas, in March 1833, and collected 750 species of plants and 150 specimens of birds in the almost two years he worked in central Texas.

Although Turk’s cap will adapt to full sun (and I do have several blooming like crazy in west sun), I really think it should be ideally planted in morning sun, afternoon shade.  I have found that if Turk’s cap is in deep shade, the blooms are limited.  Although Turk’s cap is drought tolerant, the plant will wilt noticeably in full sun.  It loves heat, and is a dependable August bloomer.  The bloom season runs from May to November.

For a low maintenance light to medium-shade garden, mix Turk’s cap with southern wood fern and caladiums.

Okra Pilau For Dinner Tonight

I am making this okra recipe tonight!  Last summer I let you know of my obsession  with okra. For an okra review: click here.

Green Fingers Okra in a Dallas Garden

Okra Pilau

Yield: 4 servings

8 bacon slices, diced
11/2 cups sliced fresh okra*
1 large onion, chopped
1 green bell pepper, chopped
11/2 cups uncooked long-grain rice
1/2 teaspoon salt
1/4 teaspoon pepper
2 cups water or chicken stock

Cook bacon in a large skillet until crisp; remove bacon, reserving 2 tablespoons drippings in skillet.

Sauté okra, onion, and bell pepper in hot drippings over medium-high heat 5 minutes or until tender. Stir in rice and next 3 ingredients; bring to a boil. Cover, reduce heat, and simmer 20 minutes or until water is absorbed and rice is tender. Remove from heat; stir in bacon. Let stand 5 minutes.

You can use any variety of okra (preferably from your garden) for this recipe that Tim says will make okra lovers of us all.

Red Velvet Okra will be in my skillet tonight.  I love it’s color even though the okra turns green when cooked.

Red Burgundy Okra, Dallas Garden BuzzYou can’t eat Okra leaves but how lovely they are to have in your garden. Harvesting Okra every day requires your careful attention and looking in and around the whole plant and under every leaf to find Okra that may be hiding.  if you let it go an extra day, you end up with giant Okra good for drying and seed saving but not much else.

Okra Leaf, Dallas Garden Buzz

For the healthy benefits of okra including a hair rinse recipe, read this.

Ok now, all this about Okra is persuading me to get out in the garden and start picking.  Hope you are, too.

GARDENING WITH PERENNIALS

In Texas, our 52-week growing season has a double-edged sword: Yes, we can grow flowers in the garden all year round (well, the vote is still out on August).  But if your plant choices are flats and flats of annuals—changed out by the season–you’ll either throw out your back or overdraw your checking account.  Or both.

Seldom in life can one say: unequivocally here’s the answer.  With a vision of Oprah guiding my thoughts:  Here Is The Answer: Practically Perfect Perennials.  They bloom, come in every size, shape, and color of the color wheel, and make a return visit to your garden next season.  Ideally, mix annuals (one season show) with perennials (several week bloom) for long lasting color.

Gardeners’ hearty embrace of the charms of perennials has only come about in the last decade or so.  I remember a Fort Worth nurseryman telling our class on perennials that he couldn’t give them away in the 1980s.  Traffic stopping masses of white periwinkles were as ubiquitous as padded shoulders and Dynasty.

As purchasing habits have moved from annuals to perennials, the look of gardens has also changed.  Carefully chosen groupings of perennials tickle the senses with different bloom shapes, colors, and leaves in comparison with the banality of one type of annual.

Enough already.  I’m converted.  I see the light.  I want to add perennials to my garden beds.  How do I start?

Soil Prep: You can’t escape it in North Texas.  Lots of compost, 3 inches of expanded shale, tilled in.  Run a drip system or soaker hose up and down your beds.  Plant, remembering the eventual height and width of the plant (tall goes in the back).  Mulch like your plant’s life depends on it, at least 2-3 inches.

What do I choose?  I start with color.  For example, for a house with brown brick you might consider going with warm, bright colors.  Hot yellows, warm oranges, and flaming pinks pop against the neutral brown.  Pick a unifying color; I almost always choose blue or purple.  It goes with everything.

Now life gets interesting.  I use a yellow legal pad and some good gardening books.  Make of list of plants you can’t live without.  Like daylilies? Bee balm? Search for background perennials with high, mid-level, and low front of the bed plants.  Think about bloom season to narrow your plant choices.  Early spring? Early summer? Fall? To narrow your selections and make your garden more interesting, look at plants by bloom type.  The four flower types are spike (salvia), tubular (petunia), ray (daisy), and umbel (lantana).  You want to include each type of bloom.

Spike, Tubular, Ray, Umbel Flower Types, Dallas Garden Buzz

Spike, Tubular, Ray, Umbel Bloom Type

Also consider leaf shape and size.  The huge leaf of a Mexican sunflower contrasts well with feathery yarrow or long and narrow salvia.

Cannas, Dallas Garden BuzzOne of the selling points for cannas is their huge leaf, some varieties come now in shades of purple.  For purple heart, the leaf is the big draw of the plant; the flower is small and insignificant.

Stumped or overwhelmed?  Don’t do it on your own.  Go to the outstanding arboretums and botanical gardens in the area for ideas.  Stroll the aisles of good nurseries and talk with the knowledgeable employees.  Call the Dallas County Master Gardener Help Desk at 214/ 904-3053 for assistance.  Oh, and have fun!

Cantaloupe Harvest

Most of us  believe you reap what you sow. We diligently follow  gardening advice and planting dates, prepare the soil, pray for rain, and then we hope!   This year we are enjoying a bounty of cantaloupes; 17 have been counted in one of our  raised beds.  Last year we had what Jim refers to as “insect activity” and not many cantaloupes.

Cantaloupe in the Garden

The variety we planted is Ambrosia.  If you will look on the right hand side of our blog, you will find our Garden Journal with all the details of our veggie gardening.

The Joys and sorrows of our garden experiment are recorded there.

The Cantaloupe was planted May 26th and will be eaten all through August.  When all the Cantaloupe is gone, Jim says we will be planting bush beans.

As summer wanes and we look forward to a drop in temperature, the gardeners at our Demonstration Garden are happy to  indulge in the sweetness of homegrown cantaloupe. More Fall gardening info right here.

Cantaloupe ripe and ready to eat

Ornamental Tree for Texas


JAPANESE MAPLES ARE LOVELY, BUT…..

You really can’t beat a Japanese maple for shady locations in your yard, but if you have a spot, like I do, on the edge of mature trees, you might consider one of the small ornamental trees that do well in north Texas.

Texas Redbud Cercis canadensis var. texensis

Texas Redbud Tree

What would spring be without redbuds?  Texas actually has three native redbuds, but you want to choose the right one for our alkaline, clay soil.  The eastern redbud brightens up the piney woods of East Texas.  The Mexican redbud grows as a multi-trunk tree on the rocky limestone soils of West Texas.  It cannot tolerate poorly drained soil.

As in “The Three Bears” children’s story, the third type, the Texas redbud, is just right–for north and central Texas.  It is smaller and more drought tolerant than its eastern relative, with thick, leathery leaves with wavy margins.  The Texas redbud is also commonly multi-trunked and will grow in well-drained clay.

Of course, we plant redbuds for their spectacular show of pink blooms in the early spring.  This small tree grows 15 to 20 feet tall and wide.

Mexican plum Prunus mexicana

Mexican Plum Tree

The Mexican plum plays on the same playground as the Texas Redbud. Each bloom at the same time in early spring and are about the same size. Consider planting redbuds and Mexican Plum together along your property line or as understory trees in a wooded area for breathtaking spring color.  The magenta flowers of the redbud contrast beautifully with the cloud of white blossoms from the Mexican plum.

Mexican Plum Tree FruitLike the Texas redbud, the Mexican plum is very drought tolerant, living on rainwater alone in all but the most extreme situations.  It grows 15 to 35 feet tall by up to 20 feet wide.  The one-inch wide white blooms are an important pollen source for bees.  Small oval plums—which will stain a sidewalk or patio—appear in late summer and are favorites of birds and small mammals.

Eve’s Necklace Sophora affinis

Fruit and Flower of Eve's NecklaceThis lovely small tree rewards gardeners all year round.  In spring, it is covered with 4- to 6-inch long clusters of pea-like pink flowers.  Green glossy leaves in summer are followed by distinctive black seed pods and yellow fall color.  The pods, from which the tree gets its name, resemble a black string of beads.  (Caution: the seeds are reportedly poisonous.)

 

Eve’s Necklace grows 15 to 25 feet tall by 10 to 20 feet wide and can be planted at the edge of or slightly under large shade trees like cedar elm.  It is related to the Texas Mountain Laurel Sophora secundiflora, which is evergreen.

Fall’s around the corner, and that would be the perfect time to add a small ornamental tree to your landscape.

Looking for Joy in Summer

Sometimes when the heat sets in,it can get discouraging; energy seems in short supply. Even the most loved of gardens seems,well not as lovely as it did.  Don’t give in to those thoughts or worse yet actions, such as avoiding your gardening chores.  If you grow lemon verbena,  you can have a delicious treat at the end of  weeding.  In fact, this wonderful herb can be a treat every time you walk by it; it smells more like lemon than a lemon.

Lemon Verbena,Dallas Garden Buzz

Just in case you do not have lemon verbena in your garden, a few facts to know before you head out to buy one.  Lemon verbena is a tender perennial that means it will return year after year, provided it doesn’t freeze to death.  It is hardy to about 25 degrees !   In our experience it seems able to tolerate lower temps for brief periods especially if it is carefully mulched in fall.  This herb is pretty,pale to medium green pointed leaves,very tiny flowers, but to be honest it is not a beauty.  In our herb gardens it will be about 3 to 4 feet tall and tends to sprawl a bit. In ideal growing situations (you already guessed ideal isn’t here) it can reach 15 feet.  But lets not let that upset us,it still will be very happy in good well-drained soil and especially if it gets afternoon shade  and a reasonable, not excessive amount of water.

Lemon verbena is a native of Peru and surrounding countries and wasn’t introduced into Europe until the 18th century–so–no interesting medieval recipes  for amazing cures using our herb.  That’s not a worry either you will love lemon verbena leaves in your tea.

Lemon Verbena Tea, Dallas Garden Buzz

It can be used alone as an herbal tea.  This herb has a strong lemon fragrance so it really doesn’t take a great deal to make a delicious difference in your drink.  Do not be afraid to experiment here–no known dangers associated with lemon verbena. I find that a small stem of herb(perhaps 6 leaves) and the stem can be added when brewing a pot of tea using one family sized or about 3 regular tea bags let this steep for about 10 minutes then cool and serve over ice  you can remove the herb–or one lucky person –that would be you–you grew it after all–can have it in the glass.  The same proportions apply to green tea,maybe a bit prettier since the color sets off the color of the herb.

Just a few more points–if you are just planting your lemon verbena–no tea for you yet!!!  You need to allow the plant to grow  a bit before you harvest; but it grows fast.  Never over harvest. The plant naturally needs leaves to make its food.  Be patient soon you will have plenty. You may consider several plants; once you taste your tea I feel sure this will be the case. This herb is grown from cuttings. The seeds are very difficult to get to grow i’m sorry to say but in spring at least you will be able to find it quite readily in nurseries that sell herbs.

As always, never brew tea from herbs that have been sprayed with chemicals.  The best time to gather any herb is in the morning.  Rinse you lemon verbena briefly in cold water if you feel the need and enjoy!!  This herb is one of the best for drying-no special equipment needed- sniping  small bunches of leaves and laying them in an out of the way place (a word to the wise–away from any possible interference from cats)  just leave to dry and when dry; store airtight.  It stays amazingly fragrant so a hot steaming cup of lemony tea will brighten up a cold day which will come one of these days.

If you come to visit us at The Demonstration Garden on Joe Field Road, don’t forget to crush a leaf of lemon verbena; you will love it and I hope you also grow your own and put it to good use.   It will add joy summer and winter. No calories, no guilt!

Noah’s Ark WaterGardens

Themed gardens are very popular now.  Gardening magazines feature articles on “Growing Your Own Salsa Garden” (tomatoes, cilantro, peppers, onions), a Marian or Biblical Garden concentrating on those plants found in the bible, and moonlight gardens featuring white/light colored plants that glow in a full moon and flowers that bloom at night.

Even a pond could have a veritable Noah’s Ark of water plants– and with Noah saving the animals during the 40 days and 40 nights of rain and flooding, what theme could be more appropriate for a water garden.   The DemonstrationGarden’s small pond contains at least two of these “Noah’s Ark” plants that are readily available in area nurseries.

Parrot Feather in Demonstration Garden Pond

So come on board the Ark and try a few of these animal themed water plants in your pond:

Horsetail Rush: This 2-3 foot spiked plant was used by Native Americans as a scouring agent as its stiff stems contain silica.  There is also a pretty variegated variety called Zebra Bulrush that has white stripes along the green spikes.  It grows to about 2-5 feet.  Both of these plants are very easy to grow and will tolerate some shade as well as full sun.

Lizard’s Tail:  The bright green foliage of this plant has fragrant, 4-6 inch spikes of fragrant white flowers that look like a lizard’s tail.  It grows well in shade and flowers in the spring.

Cardinal Flower:  A favorite of hummingbirds, its bright red flowers appear in the summer on 2-3 foot tall plants.  It prefers full sun.

Parrot's FeatherParrot’s Feather:  This beautiful feathered plant is a must for water gardens, especially those in part shade or even full sun.  Its appearance softens a pond and it provides oxygen for fish that also use its long trailing stems to hide or lay their eggs.  It can be grown in submerged pots or left to trail on top of the water.  The Demonstration Garden has a nice stand of parrot’s feather growing in its pond.    In the evening, the plant closes up and a drop of water sparkles on the end of the feathered fronds.

Chameleon Plant: Heart shaped leaves of crimson, green, yellow and cream decorate this showy plant that can be grown barely submerged in a pond.

Lousiana Iris “Black Game Cock”: Its velvety black-violet flowers with a gold crest in the center are a beautiful addition to a full sun pond.

Canna “Bengal Tiger”:  With showy large yellow and green striped leaves and large bright orange flowers, this tropical canna thrives in full sun.    

        Frog's Bit, Dallas Garden BuzzFrogbit:  This small floating plant looks similar to a miniature water lily, though it gets its name from how it resembles the chin of a frog in water.  Tiny cup shaped white flowers appear in July and August.  Be careful though, this plant can be aggressive and easily cover a pond.  Keep it thinned!!

Cattail, Dallas Garden Buzz

Cattail:  There are many species of cattails growing wild throughout the US.  Some may grow up to 6-8 feet tall.  Often the Dwarf Cattail, with a maximum height of 3 feet, is used in ponds as a background plant.  Cattails require full sun to grow well and since they spread by rapidly by creeping root stalks and seeds, it is best to grow them in containers.

Finally, during those forty days and forty nights of rain, what plant would Noah have found very useful (and which is found at our DemonstrationGarden)?   An Umbrella Palm, of course.

Umbrella Plant, Dallas Garden BuzzThis readily available plant grows 3-4 feet tall in full or partial sun.  With its long strap-like leaves that form an umbrella shape, it would probably be most appreciated by Noah and his family.

Do you have a favorite water garden “Noah’s Ark” plant to add to this list?  Let us know.

Rudbeckia Nitida ‘ Herbstonne’

Dallas County Master Gardeners and our visitors have been admiring a statuesque green-eyed coneflower in our garden all through July. And why shouldn’t they? Rudbeckia Nitida ‘Herbstonne’ is no slouch. It stands 4 feet tall featuring large daisy like flowers  that surround  a green cone. Even its foliage is arresting with rich green, deeply cut leaves at its base. Stunning!

Large Coneflower at the Demonstration GardenWith a good deadheading after the first bloom, it will flower all through the fall.

Looking up Through Rudbeckia HerbstonneStand and gaze at it, after  finishing garden chores, of course. You may be in line with the bees and butterflies who adore it.

Another View of Rudbeckia HerbstonneThis perennial appreciates  full sun and well drained soil in a Water Wise Garden.

To Eat or Not To Eat: That is the Question

They were grown by Thomas Jefferson at Monticello in 1812 as an arching vine on both sides of the terraces, while in Africa and Asia its edible fruit pods play an important role in native cooking.  What is this highly ornamental vine?  It is the hyacinth bean, also known as Egyptian or Indian bean.

Hyacinth Bean Vine

The hyacinth bean, Dilochos lablab/Lablab purpurea, is a very fast growing, highly ornamental vine.  Dilochos is from the Greek meaning long or elongated; purpurea means purple; and lablab is the Egyptian or Arabic word for the dull rattle of seeds inside the pod.  It was introduced to European gardens in the 1700’s and sold in America by the early 19th century.  With the hyacinth bean’s showy, long and interrupted spike-like light or dark purple flowers and beautiful one inch wide purple pods, these fast growing annual 6-20 foot twinning vines with their lush dark green foliage tinged with purple are highly recommended for use on arbors and trellises.

Here at the Garden we grow two varieties of hyacinth bean:  the more common purple variety with its black and white seeds and a white variety that has mocha and white seeds.  Each of these grows easily in full sun, in rich soil and with adequate water.  Seeds may be soaked or scarified for quicker germination.

Our Vine in Full Bloom Summer 2012

There is controversy over whether the pods and seeds are edible.  In Africa and the Far East, the flowers, pods and seeds are eaten.  However, the mature pods and dry beans contain a high amount of cyanogenic glycocides, a quite toxic substance.  Mature or dry beans must not be eaten raw.  They must be soaked overnight, then boiled in a lot of water.  Even doing this, some people are susceptible to the toxin and, in general, eating hyacinth beans is not recommended.  Rather, just enjoy the hyacinth bean as an ornamental for its lovely flowers and pods.  You won’t be disappointed.
