Cultivation Details

We have very little information on this species. It is not frost-hardy but can be grown outdoors in Britain as a half-hardy annual and probably requires a dry to moist light or medium well-drained soil in a sunny position.
Pectis is unusual among Compositae in having the C4 photosynthetic pathway and the accompanying Kranz anatomy - leaves with vascular bundle sheath cells that contain numerous chloroplasts. All of the closely related genera have the C3 pathway. The selective advantage imparted by C4 photosynthesis (greatly reduced photorespiration in bundle sheath cells) has enabled Pectis species to occupy a variety of hot, dry habitats including deserts, tropical and subtropical grasslands, arid scrublands, and tropical beaches[

If you have sufficient seed it may be worthwhile trying an outdoor sowing in situ in mid to late spring.
