Bushy plants to 10 inches tall with dark spots on the stems. Flowers are mostly white in October and November. Propagates easily from leaves pulled off. Mexico.
In an email from George Hinton he says "Sedum hintoniorum grows in oak and pine woods between 1,700 and 2,500 m. in the municipalities of Aramberri and Zaragoza. Although S, macdonaldii, S. palmeri and S. wrightii occasionally grow on gypsum, the only obliged gypsophiles in Nuevo León are S. booleanum and S. gypsophilum."
I had mistakenly stated that S. hintoniorum grows on gypsum and George caught my error. Thank you George!
