About

Sedum praealtum, also known as shrubby stonecrop or green cockscomb, is a small, woody succulent shrub in the stonecrop family that is native to Mexico.

How to grow it

It can be used as a bonsai due to its treelike appearance and it bears a resemblance to the Jade plant. It easily grows in rock gardens in well-drained, poor soils. Propagation can easily be done by cuttings and the plant is not cold hardy.

Uses

A spermicide developed from this plant, that helps women control birth rates without any major side effects, was around 20% more effective than nonoxynol-9. Its leaf substance has been traditionally used for burns, hemorrhoids and dysentery, gum inflammation, and as well as an eye drop for conjunctivitis and irritations.
