Pterodiscus Speciosus
IntermediatePterodiscus speciosus
A sesame-family caudex with beautiful pink-purple flowers and compact form.
About
Pterodiscus speciosus grows in dry regions spanning South Africa, Zimbabwe, and Mozambique, belonging to the Pedaliaceae (sesame) family. Its primary appeal is the profusion of beautiful pink to purple trumpet-shaped flowers produced on a compact plant. The caudex is a short swollen stem from which multiple branches with leaves arise. Flowers are characteristic of the sesame family—funnel-shaped and vividly colored. Growth is moderately slow but flowering is reliable and ornamentally rewarding. Full sun to bright indirect light with extremely porous soil is appropriate. Moderate watering during growth and complete winter drought are standard. Its compact size and beautiful flowers make it an accessible entry into sesame-family caudex collecting.

Growing Tips
Light & Placement
Grow in full sun to bright indirect light. Insufficient light leads to a loose plant and fewer flowers, so keep it bright.
Watering
During the growing season water moderately once the soil has dried. In winter let it drop its leaves, stop watering and keep it dry.
Temperature & Overwintering
Cold tolerance is somewhat low, so overwinter indoors where 10°C or above can be maintained. Withhold water during the cold months and keep it on the dry side.
Soil & Repotting
Use an extremely fast-draining mix based on pumice and akadama and avoid sogginess. Growth is slow, so repot only once the roots have filled the pot.
Dormancy Care
It drops its leaves and goes dormant in winter, so keep it dry in a bright, warm spot. Resume watering in spring once new growth appears.
