Spiderwort is stunning color for shade

Native Plant Focus: Spiderwort

Tradescantia virginiana

 

Spiderwort (1)

An easy to grow clump-forming perennial, spiderwort is a Texas native which thrives in nearly any growing conditions—including shade. This plant’s deep blue to violet purple flowers with their contrasting yellow stamens bloom continuously for several months beginning in March in southeast Texas. Although each blossom lasts only about one half day, the numerous buds contained in each flower cluster provide new flowers each day. Spiderwort is a member of the iris family with long narrow bright green leaves that offset the unusual, slightly fragrant blue flowers.

Spiderwort’s scientific name, Tradescantia virginiana, is in honor of John Tradescant who served as the gardener to King Charles I of England. The plant’s common name, Spiderwort, has its origin in the angular arrangement of the leaves which suggest the shape of a squatting spider.

Easy care & adaptable

This highly adaptable plant will thrive in nearly any conditions although it prefers slightly moist soil in an area of dappled shade. When planted in drier areas, the plant adapts. Included in spiderwort’s many assets are its ability to grow in any soil as well as in light conditions ranging from shade to full sun.  In addition, Spiderwort has no known disease or pest issues.

Attract pollinators

In the home landscape, Spiderwort is a beautiful addition to a native plant garden, pollinator garden, shade garden or natural area. Spiderwort also adapts to containers. Many types of bees are attracted to the deep blue color of the spiderwort blossoms.  Bumble bees are the plant’s major pollinator although honeybees, small carpenter bees and halictine bees also provide pollination. Butterflies enjoy the nectar of this plant while syrphid flies feed on the pollen.

The distinctive and beautiful flower of Spiderwort adds color to shady spots in the landscape through spring and into summer.

Missouri Plants has some wonderful close-up photographs of this wide-ranging native.

For those interested in foraging, both spiderwort leaves and flowers are edible. The leaves are useful in salads, soups or teas while the flowers can also be used in salads or can be candied.

Where to find it

Obtaining spiderwort is easy since many on-line retailers offer both the seeds and the plants. Spring is a perfect time for shipping these plants before the Texas heat arrives. April is an ideal planting time for either Spiderwort transplants or seeds. Since Spiderwort grows quickly, planting it now will provide for pollinators in only a few short weeks.

Grow a native American vegetable and treat your landscape and palate alike

Helianthus tuberosus

Cultivated for centuries prior to the arrival of European explorers and settlers, our country’s only native vegetable is also a Texas native sunflower. The “jerusalem artichoke” or “sunchoke” is the enlarged underground stem of helianthus tuberosus, a type of sunflower in the aster family with edible tuberous roots. While commonly regarded as native vegetables, potatoes, tomatoes, corn and peppers all originated either in Central or South America.

Today, we take the food on our plate for granted, but the History of Vegetables  is a fascinating study.

The common name “Jerusalem artichoke” is likely a corruption of the Italian girasole (turning toward the sun) which is a trait shared by all sunflowers. In more recent years, the edible tubers of helianthus tuberosus have become known as “sunchokes”.

Sunchokes have a delicious, sweet nutty taste.  As an extra bonus, these tubers are nutritious and an excellent source of iron, potassium and fiber.

The original distribution of this native Texas sunflower is unclear because the plant was transported to many different geographic locations for cultivation by Native Americans.  Today, helianthus tuberosus can be found along the edges of wooded areas, in former fields and along roadsides.

Helianthus tuberosus

This showy sunflower is also sometimes grown simply for its bright yellow blooms and tall, fast growing stems. Broad, thick leaves and rough hairy stems add to the visual attractiveness of this native plant.

Blooming in late summer and early fall, helianthus tuberosus requires full sun to part shade. A tough and versatile plant, this sunflower will grow in moist or dry soil and tolerates drought, heat and frigid temperatures. Because of these qualities, it’s very easy to grow. Helianthus tuberosus is extremely useful in the garden where it can quickly become a temporary summer screen, a stunning background for a native plant border or the sunny edge of a natural wooded area.

Nectar source for butterflies

This particular sunflower is beneficial for both insects and wildlife. The large yellow flowers offer nectar for butterflies, pollen for bees while also supporting many predatory and parasitoid wasps, flies and beetles. In fall, the seed heads attract birds while the large plants offer cover for small wildlife.

Beekeepers have noted that helianthus tuberosus  is an excellent honey plant resulting in a clear amber product when harvested.

Very little is known about pests or diseases which damage this plant. It appears to be quite resistant, which contributes to its easy to grow nature. In the southeast Texas climate, the optimum planting time is early spring with the main harvest in fall. Since helianthus tuberosus is a perennial plant, once started in the garden, it’ll return each spring from tubers left in the soil.

Growing helianthus tuberosus in your garden or landscape offers new opportunities for applying culinary skills as well as providing beauty, food for pollinators and cover for wildlife.

The edible tubers or sunchokes can be harvested beginning within two or three weeks after the flowers fade. Harvesting can continue after the first freeze damages the stems and leaves of the plant. Each plant will produce approximately 2-5 pounds of sunchokes. When left in the ground after the first frost, the tubers become sweeter and crispier. To preserve the freshness, store sunchokes in a zip top plastic bag in the refrigerator. This strategy preserves the tuber’s natural moisture.

While sunchokes are frequently used in cooking as a potato substitute, unlike potatoes, they can be used raw and add a nutritious crunch to salads. Sunchokes are also an excellent vegetable for pickling.

Add Height and Habitat with Oxeye Sunflower

Native Plant Focus: Oxeye Sunflower

Heliopsis helianthoides

Oxeye Sunflower (1)

[By Ann Hall, Environmental Education Specialist, enviro@thewoodlandstownship-tx.gov]

With showy yellow daisy-like flowers attractive to hummingbirds, butterflies, beneficial wasps, flies and native bees, the oxeye sunflower (Heliopsis helianthoides) blooms all summer and into fall.  Since this plant is not a true sunflower, it is known by several common names including ‘false sunflower’, ‘oxeye daisy’ and ‘smooth oxeye’.   This upright clump-forming Texas native perennial is very effective when used in a garden border, native plant garden, or as an addition to a pollinator garden.

Oxeye sunflower is easy to grow and maintain

It thrives in full sun but will tolerate part shade.  The low watering requirement and tolerance to all soil types make it a perfect plant for our hot Texas climate.  At maturity, oxeye sunflower will reach a height of 3-6 feet and spreads into 2-4 foot clumps.  Dead head (remove spent flowers) to keep this long-blooming perennial covered with blooms.  No known pests or diseases affect this extremely resistant plant.

Ground Bee on Oxeye Sunflower

Nature is enhanced by the oxeye sunflower since it is pollinated by a specific ground-nesting bee.  Birds use the seeds as a winter food source while the plant’s stems provide cover for beneficial insects.  Starting the oxeye sunflower from seed is easily accomplished in the cooler fall and winter months.  Although it is possible to divide the mature clumps, this strategy is less successful than growing from seed.

Seeds of oxeye sunflower are readily available from online retailers who focus on seeds of Texas native plants. Watch for local plants sales offering starts of oxeye sunflower or check local native plant retailers.  Enjoy not only the summer to fall color this plant provides, but also the hummingbirds, butterflies, bees and other fascinating pollinators it will attract to your garden.

Attract Hummingbirds All Summer with Texas Red Yucca

Native Plant Focus:  Texas Red Yucca

Hesperaloe parviflora

More effective at attracting hummingbirds than a feeder, the Texas Red Yucca is also a nectar source for butterflies and native bees.  Actually a member of the Century Plant family, the Texas Red Yucca thrives in our hot Texas summer although it is cold tolerant enough to survive freezing temperatures.

With low watering requirements after establishment, this striking perennial evergreen shrub produces dramatic 3-4 foot spikes of pink to coral to red tubular flowers.   These beautiful flower spikes provide focal interest in landscape beds, large containers, rock gardens or as a single specimen plant.  Each bloom produces a seed capsule which dries to offer winter interest in the landscape.  The evergreen leaves turn a deep shade of purple in cold weather, further enhancing the garden.

Thriving in full sun to part shade and needing only natural rainfall, this plant is adaptable to any soil. Maintenance is minimal – removing the dried flower spike before spring begins is optional.  Planting this succulent in your landscape or a large container will provide beautiful blooms from May through October.  Texas Red Yucca is readily available in most local retail outlets offering bedding plants as well as those specializing in Texas natives.  Enjoy this easy to grow plant along with the hummingbirds and insect pollinators it will draw into your garden.
