Cross Timbers (includes Fort Worth, TX)
Year-round
Superb penstemon comes from rocky canyons and washes in Arizona and New Mexico, so Dallas-Fort Worth is a real stretch for it. Treat it as a cultivation-only plant that needs sharp drainage and full sun. Humid summers and heavy clay are the main risks.
- Use full sun and very well-drained soil
- On clay, plant in a raised bed or mix in plenty of gravel
- Once established, keep water low
- Expect it may be short-lived here and reseed if it does well
Fall
Fall is a good time to plant or scatter seed. Cool weather helps roots settle before winter.
- Plant while the soil is still warm
- Water after planting, then taper off
- Cut spent stalks or leave some to drop seed
- Skip fertilizer
Winter
The plant is listed as hardy to zone 5, so it should handle Dallas-Fort Worth cold. Wet winter soil is a greater risk than a freeze.
- Skip winter watering
- Make sure rainwater drains away from the crown
- Trim dead growth in late winter
- Do not cover the crown with heavy mulch
Spring
Spring is bloom time, with coral-red flowers on tall stalks that hummingbirds visit. Plant in spring or fall in gritty ground.
- Water every 5 to 7 days for the first month
- Do not fertilize
- Stake tall stalks if wind bends them
- Deadhead some blooms and leave some to reseed
Summer
Humid Texas summers are hard on desert plants. Water lightly and keep the crown dry.
- Water deeply only every 2 to 3 weeks in a dry spell
- Water at the base and avoid wetting the foliage
- Use gravel mulch and keep wood mulch away from the crown
- Do not water after heavy rain
