Synonyms of Haworthiopsis attenuata (5) (Updated on 11-17-22 from Plants of the World Online): Aloe attenuata Haw., Apicra attenuata (Haw.) Willd., Catevala attenuata (Haw.) Kuntze, Haworthia attenuata (Haw.) Haw., Haworthia pumila subsp. attenuata (Haw.) Halda

Haworthiopsis attenuata (Haw.) G.D.Rowley is the accepted scientific name for this species of Haworthiopsis. It was named and described as such by Gordon Douglas Rowley in Alsterworthia International in 2015. It was first named and described as Aloe attenuata by Adrian Hardy Haworth in Transactions of the Linnean Society in 1804.

Accepted intraspecific names (3) (Updated on 11-17-22 from POWO: Haworthiopsis attenuata var. attenuata (autonym), Haworthiopsis attenuata var. glabrata (Salm-Dyck) G.D.Rowley (2015), Haworthiopsis attenuata var. radula (Jacq.) G.D.Rowley (2015). *When an infraspecific taxon is named, an autonym (“type-specimen”) is automatically generated whose description is closest to the (original) species. All have their own list of synonyms…

The genus, Haworthiopsis G.D.Rowley, was also named and described by Gordon Douglas Rowley in Alsterworthia International, Special Issue 10:4 in 2013.

As of 11-17-22 when this page was last updated, Plants of the World Online lists 19 species in the Haworthiopsis genus. It is a member of the plant family Asphodelaceae with 41 genera. Those numbers could change as updates are made on POWO.

Before, the two-lipped flowers were a distinguishing feature of the Haworthia genus. After extensive study, more detailed features of the flowers clearly identified three separate genera (Haworthia, Haworthiopsis, and Tulista). This certainly doesn’t mean the genus names won’t change again. You just never know… You can use whichever name you choose because both scientific names were validly published. It is just that Plants of the World Online by Kew (Royal Botanic Gardens) and whoever is in charge of plant names says Haworthiopsis is now the accepted genus name.

I received this Haworthiopsis  ’Super White’ from Nico Britsch of Succulent Market on August 27, 2020. He contacted me with a request to mention his business in a post in exchange for a few plants. How could I refuse that?  

I selected five plants, including this Haworthiopsis ’Super White’. The plants were nicely packed and arrived quickly and safely. The plants were in a 4” pot, larger than many you buy online or at retail stores. The Haworthiopsis ’Super White’ was 3 1/4” tall x 5 1/2” wide which is a very good size… I didn’t measure the plants until October 6 when I wrote the post about the plants and Succulent Market.

Nico is the third generation of cactus and succulent growers in California. He said his grandfather selected this Haworthia fasciata over a period of years to have more white on its leaves thus making it better for low light situations. There are MANY cultivars available similar to this one… But, there is an issue with the name…

Haworthiopsis attenuata ‘Super White’ on 10-6-20, #746-9.

Family: Asphodelaceae
Origin: Eastern Cape Province in South Africa
Zones: USDA Zones 9b-11 (30 to 40° F/-1.1 to 1.7° C)
Size: 4-8” ? tall x 5-6” wide ?
Light: Light to part shade. Does not appreciate full, direct sun. 4-6 hours of filtered light is ideal.
Soil: Fast-draining. If grown in a pot used good quality potting soil amended with 50% pumice, or 2 parts potting soil with 1 part additional perlite and 1 part chicken grit.
Water: Regular watering during the summer and less during the winter. This is a summer dormant species…

Haworthiopsis are native of the Eastern Cape Provinces in South Africa where they grow in grassy areas among small shrubs. In this situation, they receive filtered light. Many websites say they need bright light or full sun, but that is not likely the case. If you grow this plant in full sun, the leaves will likely burn. Of course, that depends on your location and how long they are in the sun… I don’t really have many succulents that “prefer” full sun over light to part shade here in midwest Missouri (USA), so they stay on tables on the front porch from May through mid-October on the west side of the house. They receive bright light but not full sun. There are periods of time in the afternoon where they get a little direct sun which also depends on where they are situated. They may get moved around a bit depending on their requirements.  

I have not grown any Haworthiopsis (or Haworthia) for many years, and never one like Haworthiopsis attenuata. I have grown many Aloe for MANY years which probably have basically the same requirements. They are all SUMMER DORMANT which means they supposedly take a rest during the hotter months for 6-8 weeks from sometime in July through mid-August. Otherwise, their main growing period is from April through November, or thereabouts. From December through March, they are not exactly dormant, but their growth is slowed down so it is advisable not to hardly ever water during that period either. During their summer dormacy period, their growth above the soil kind of stops, but they are renewing their roots using material from the old roots. SO, during that time, you should avoid giving them too much water as well. Generally, when I water during the summer, I just go over the succulents without overly soaking them.

You can read my Cactus Talk & Update and Cactus & Succulent Tips to get my opinion about growing cactus and succulents.

When you bring your new plants home from the store, you need to check their roots and the soil to see if they are wet. If so, you may want to re-pot it right away. It is advisable to re-pot them in a better potting soil more suitable for cactus and succulents.

Well, besides the genus name changing, the species of this plant is likely NOT Haworthiopsis fasciata. I am not a Haworthia/Haworthiopsis expert, but judging by the leaves, this plant is a Haworthiopsis attenuata Haworthiopsis attenuata has leaves that are narrower and longer, and have “tubercles” on the lower surface like Haworthiopsis fasciata, but also on the upper surface. Haworthiopsis fasciata only have the tubercles on the undersides of the leaves while the upper surface is smooth. According to information online, Haworthiopsis fasciata is rarer (while available online), and Haworthiopsis attenuata is more readily available. Also, Haworthiopsis fasciata has fibrous leaves and H. attenuata does not and the latter is supposedly a larger plant. They both subdivide and offset readily and prefer growing in a cluster.

When I was writing this page on December 8, I took a couple more photos and noticed the potting soil was very hard. SO, I mixed enough Miracle Grow Potting Soil and pumice (50/50) and gave it a fresh mix. I left it in the same pot that it came in because it is still big enough (4″). After that, I put it on the shelf in my bedroom. It’s amazing how much I learn when I am writing plant pages…

As I mentioned earlier, I have not had any Haworthia companions for quite a long time. I had a Haworthia emelyae and H. herbacea in 2009 when I was a succulent newbie and I overwatered them and they eventually died. Well, I think they were both a more delicate species in the first place. The Haworthiopsis attenuata ‘Super White’ is apparently not that delicate so I don’t see any future problems with it as long as I follow the “rules” which seem pretty simple.


Haworthiopsis attenuata ‘Super White’ at 3 3/4″ tall x 51/2″ wide on 8-17-21, #826-27.

The Haworthiopsis attenuata ‘Super White’ has done very well outside over the summer. It has grown 1/4″ taller since it arrived in August 2020.


Unfortunately, the Haworthiopsis attenuata ‘Super White’ died over the 2021-2022 winter…
