What Makes Wavyleaf Soap Plant Special

The wavyleaf soap plant is a California native that belongs to the diverse soap plant family.

Important Conservation Note

Before adding wavyleaf soap plant to your garden, it’s important to know that this variety has a conservation status that requires attention. Always source plants or seeds from reputable native plant nurseries that use responsibly collected, locally appropriate genetic material. Never collect plants from the wild, as this can harm natural populations.
