Suggested plants for Capitol of Texas Park

All the following plants are Texas natives and evergreen unless otherwise noted. They are drought tolerant and grow no more than three feet.

It would look best to choose only two or three of the following plants. Several are listed in case they are not available at local nurseries. Note: Calylophus berlandieri was previously recommended, but I would like to withdraw it since it is deciduous. On 11/20/12 I removed Plumbago auriculata and Hamelia patens because these two plants die back from even the lightest freeze.

Why choose Texas native plants?

“They help conserve water, reduce mowing costs, provide habitat for birds, butterflies and other wildlife, protect the soil and save money on fertilizer and pesticides.” Native plants are disappearing at a high rate which reduces “wildlife habitat and the genetic diversity necessary for balanced ecosystems. Native plants introduced into landscape plantings are hardy, less susceptible to pests and diseases and unlikely to escape and become invasive. With properly selected native plants, it may not be necessary to modify soil characteristics at all to have thriving gardens.” – from http://www.wildflower.org/whynatives/.

The criteria I used for selecting plants are:

  • Attractiveness
  • Whether it’s well-behaved
  • Texas native (exceptions are noted)
  • Drought-tolerant
  • Requires full-sun
  • Height no more than three feet
  • Evergreen

Sources for this list include http://www.wildflower.org/ and http://plants.usda.gov/java/ to determine whether the plant is a native. The following were all used for sources for lists of drought-tolerant plants.

The first plant can be seen at the Discovery Garden.

Dianella tasmanica ‘Variegata’ – Flax Lily is growing well at the Discovery Garden. It could be divided and would look nice among the newly-spread rocks at Capitol of Texas Park. It is evergreen. It’s flowers are insignificant. It is grown for it’s foliage.
