Haworthia herbacea (Mill.) Stearn is the correct and accepted scientific name for this species of Haworthia. This species was FIRST named Aloe herbacea by Philip Miller and described in Gardener’s Dictionary, 8th Edition, in 1768. Its current name was given to it by William Thomas Stearn and was first documented in the Cactus and Succulent Journal of Great Britain in 1938.
In the wild, Haworthia herbacea is a native to South Africa. It seems to grow in rocky soil and in cracks and holes on larger rocks and slopes. It readily hybridizes with other species growing in the same location.
I bought my Haworthia herbacea from Lowe’s in Greenville, Mississippi in August 2009. It did well for only a short while then started getting crown rot, possibly from overwatering. Well, I was a succulent newbie at the time and I repotted it in a larger pot when I should have left it in the pot it came in for a while longer. I found out commercial potting soil isn’t good for succulents unless it is a cheaper brand that has less peat. NOW I use 2 parts potting soil with 1 part perlite and 1 part chicken grit. The soil has to drain almost as fast as the water goes in. This species is cold hardy in USDA zones 10a-11 and prefers bright light but will also do OK in part shade.
Someday I will buy another Haworthia herbacea and see if we can get along better. If you have any comments, questions or suggestions, I would like to hear from you.
