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.
The genus, Haworthia Duval, was named and described by Henri August Duval in Plantae Succulentae in Horto Alenconio in 1809. The genus was named after Adrian Hardy Haworth, an English botanist, entomologist (the study of insects), and carcinologist (the study of crustaceans). He named a lot of plants…
Plants of the World Online by Kew currently list 57 accepted species in the Haworthia genus (as of 12/26/18 when I updated this page). Version 1.1 of The Plant List (2013) listed 166 accepted species (plus 110 accepted infraspecific names), a total of 872 synonyms, and 52 unresolved names. The Plant List has not been updated or maintained since the 2013 update. The Plant List had been a cooperative effort of the Missouri Botanical Garden and the Royal Botanic Garden-Kew. Royal Botanic Garden launched Plants of the World Online in 2017 and is still uploading data.
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. I am now experimenting with a 50/50 (more or less) mix of potting soil and pumice. This species is cold hardy in USDA zones 10a-11 and prefers bright light but will also do OK in part shade.
Maybe someday I will try another Haworthia herbacea. Time will tell.
