Beat the heat with Bluebells

 

Native Plant Focus: Texas Bluebell

Try to think of one thing that wildflowers and ice cream have in common.  Not so easy, is it?

Texas’ native wildflowers need the summer heat to survive just as many of us depend on a scoop of cold, delicious ice cream to get us through a summer afternoon.  But there’s only one wildflower that has influenced a nation of ice cream lovers more than any other.  An enchanting specimen that at one time was so abundant across the Texas prairie that a large creamery located near Brenham decided to adopt its name in 1930.  This native beauty is the Texas Bluebell.

Where to find it

Ranging southward from Montana, Wyoming and South Dakota to new Mexico, Texas and Louisiana, the Texas Bluebell (known also as Showy Prairie Gentian or Prairie Gentian), is considered by many to be the most beautiful of Texas wildflowers.   Sadly, in Texas, the plant’s range has decreased dramatically over the past century.  The upright, showy blue to purple bell-shaped flowers are so attractive in cut flower arrangements that admirers have over-picked it, drastically reducing the number left in nature to produce seed capsules.  Today, locating Texas Bluebells in the wild requires a focused effort.  In our local area, some of the isolated prairies within Sam Houston National Forest provide limited viewing opportunities.

Easy care & adaptable

With blue blooms emitting a natural iridescence and a velvety texture, the two-inch bell-shaped flowers stand upright on deep blue-green stems and leaves covered with a waxy bloom.  Texas Bluebells thrive in moist sandy or sandy loam soils and are most likely to be found along the edges of creeks, streams, or drainage areas.  This perennial plant develops a long taproot to access the required moisture from deep within the soil.  While it prefers full sun, the Texas bluebell will grow in part shade.  During periods of rain, the beautiful blue blossoms will close and will re-open when the sun emerges.  The plant is heat tolerant and continues to produce blooms during the summer when other wildflowers are past their prime.

In the home landscape, Texas Bluebells are perfect for the edges of water or rain gardens, in ornamental beds, borders or cutting gardens.  They’re easy to maintain and have no known serious insect or disease problems.  If you’re incorporating Texas Bluebells, consider beginning with young rosettes; starting from seed can be challenging.

Attract pollinators

As a native plant, the Texas Bluebell offers a number of benefits for the environment.  Birds are attracted by its tiny black seeds while hummingbirds, butterflies and bees enjoy the nectar and pollen.  Since bees are attracted to blue flowers, the major pollinator for this plant is the metallic green sweat bee, whose long tongue is able to reach the nectar deep within the large flower.  Metallic green sweat bees are one of the most prolific native bees in local yards and gardens.

Providing habitat for native bees is an important role for homeowners.  The University of Texas offers some excellent tips for improving native bee habitat.

Growing native Texas Bluebells and creating enhanced native bee habitat in your own landscape will support restoration of this stunningly beautiful blue flower.  Bluebells will begin their bloom cycle in June and continue blooming throughout the heat of the Texas summer.  Visit a local native plant retailer now to establish these rewarding plants in your own garden.

Approximately 80 years ago, the Japanese imported Texas bluebell seeds, as the flower is considered by the Japanese people to be extremely beautiful. Commonly called ‘lisianthus”, the Japanese hybrids vary in color to include white, pink, lavender and yellow.

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.

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.
