I've grouped some of my favorites below with photos and cultural information. The caudex fancier may raise the plants partially above the soil line to show off the tubers. The leaves are pinnately compound and resemble at first glance delicate carrot leaves. P.bowkeri is from the summer rainfall area in the mountains of the northeastern cape. To accommodate the tuberous roots a well draining oversize pot is preferred for this species.
Flowers appear early in the spring before the foliage.
Seeds self and may be sown immediately. The series of interconnected tubers may be separated and used for propagation. This is an interesting and easy to grow species that is uncommon in cultivation and readily fits into any collections of succulents and caudiciforms. A natural bonsai with succulent scaly brown barked stems and long flowering period makes Pelargonium cotyledonis particularily desireable. P. cotyledonis is the sole species of Pelargonium on the island of St. Helena.
