Venus' Pride Houstonia purpurea

Previously known as:

  • Hedyotis purpurea
Phonetic Spelling
hoos-TOH-nee-uh pur-PUR-ee-ah
Description

The Large Houstonia has broad terminal clusters of three or more blooms on branching, hairy stems. The flowers have four lavender-blue to almost white petals that fuse into a deep tube. Usually the central flower opens first. In its natural habitat, it can be found in many locations, such as on well-drained slopes, along streams and lakes, hardwood floodplains, moist woods, rocky upland forests, rocky bluffs, pastures, and limestone glades.  

It can be grown as a ground cover that can be mowed.  To allow it to self seed, avoid mowing until it has set its seed.  

Although this is a short-lived plant, its self seeding properties allow the plant to appear year after year.

It is sometimes confused with Houstonia longifolia, the difference being that the leaves along the stem are wider and rounded at the base and have sepals that are longer when in bloom.

Insects, Diseases, and Other Plant Problems:  Snails and slugs are common insects of this plant.
