The Story
Plant Bio
Dermatophyllum secundiflorum is a slow-growing, evergreen shrub or small multi-trunked tree native to the alkaline limestone soils of the southwestern United States and Mexico. It features dense, glossy, dark green pinnately compound leaves and produces drooping, highly fragrant racemes of purple flowers in early to mid-spring.
This species is highly valued in xeriscaping for its exceptional drought tolerance and ability to thrive in poor, rocky, basic soils. The woody seed pods contain bright red, extremely toxic seeds containing the alkaloid cytisine, requiring careful placement away from children and livestock.

Planting
How to Grow
- Select a planting site that receives full sun and has excellent drainage, avoiding low spots where water collects.
- Amend highly acidic soils with lime to raise the pH above 7.2, or plant in raised beds if the native soil is heavy and poorly drained.
- Dig a hole twice as wide as the root ball but no deeper, ensuring the crown sits slightly above the surrounding soil level to prevent rot.
- Water deeply to establish the root system, then restrict irrigation to occasional deep waterings during extended dry periods.
Pro Tip
Plant in exceptionally well-drained, alkaline soil in full sun, and never prune back into old bare wood as the stems fail to regenerate new buds from ancient timber.

Care Guide
Do
- Do plant in full sun to ensure robust growth and abundant spring flowering.
- Do ensure the soil has sharp drainage to prevent fatal root rot.
- Do protect young plants from hard freezes until they are fully established.
Don't
- Don't overwater or plant in heavy, waterlogged soils.
- Don't apply high-nitrogen fertilizers, which cause weak, leggy growth susceptible to wind damage.
- Don't prune heavily into old, leafless wood.
