Description
Xerophyta retinervis is a remarkable perennial plant native to southern Africa, renowned for its extreme drought tolerance and “resurrection” ability. During prolonged dry periods, the plant desiccates almost completely, with its narrow, grass-like leaves curling and turning brown. When rainfall returns, it rapidly rehydrates and resumes active growth, turning green within hours to days.
The species forms dense tufts or short woody stems topped with stiff, linear leaves marked by pronounced parallel veins. Under favorable conditions it produces attractive star-shaped flowers, typically violet to purple with contrasting yellow centers. Xerophyta retinervis thrives in full sun, rocky or sandy soils, and exposed sites with excellent drainage. It is well adapted to nutrient-poor substrates and requires minimal water once established.
Highly valued by collectors and botanists, this species is ideal for rock gardens, xeriscapes, and conservation plantings in warm, dry climates, where its resilience and unique life strategy make it both a scientific curiosity and an ornamental highlight.

Moderate
Xerophyta retinervis, commonly known as Black Stick Lily, is a resilient South African shrub from the Velloziaceae family, native to seasonally high-rainfall regions on rocky outcrops. This remarkable xerophyte exhibits exceptional adaptation to extreme conditions including drought, fire, and cold temperatures, with the ability to survive extended periods of desiccation. Seeds require light to germinate and typically initiate growth within 2-9 weeks when provided with consistent moisture and appropriate temperature conditions.

Growing Tips
Sow seeds on the surface without burying; do not cover with soil. Maintain consistent moisture throughout germination—avoid allowing soil to dry out until seedlings are established. Use a spray bottle or bottom watering to avoid disturbing seeds. Ensure a bright location with indirect light (avoid direct sun). Once germinated, allow seedlings to become rootbound before dividing in the second growing season. Use shallow containers for long-term cultivation as growth is very slow. Avoid repotting when possible as roots are sensitive. Keep the seedling environment humid using a clear plastic cover or lid.
