Where it grows
Pelargonium cotyledonis only occurs on a single island in the South Atlantic Ocean, that of Saint Helena.
Special features
Pelargonium cotyledonis is also known as Old Father Live Forever. This caudex forming succulent has large circular dark-green leaves with plentiful veins covering their surfaces. This is a deciduous plant that goes dormant in summer and loses its leaves. They produce pure white flowers.
Care guide
This plant is adapted to receiving very little rain in nature, so it is important to be mindful of watering regimes in cultivation. Keep them dry in summer when they are dormant and give less water in winter. Provide more water in autumn and spring. They prefer soil with little to no organic matter, so a mix involving akadama, pumice and LECA would work well. Provide them with only a light amount of shade to encourage compact growth.
Growing season
Autumn and early winter.
Propagation
Can be grown from either seeds or stem cuttings.
