Haworthiopsis viscosa

H. viscosa, Sandpoort

Haworthiopsis viscosa (L.) Haw.

viscosa
: sticky

H. viscosa
has trifarious leaf arrangement, scabrous rather than tubercled as in H. nigra. The colour and size account for the vast majority of variants. Smith has described 15 varieties. It is a proliferous species, which forms clumps. In nature they grows in all kind of situations - in shade in the middle of the bushes, in rock crevices or exposed on full sun. It is not very photogenic plant, because very often it is grazed from animals - game or goats and sheep.



Distribution map
H. viscosa is widely distributed in the eastern, central and southern Karoo and Little Karoo and it is also extends into the lower Gamtoos Valley.

H. viscosa
does hybridize with several species. The hybrid with H. scabra was described as H. tauteae, hybrid with H. longiana is undescribed and also hybrid with H. fasciata was found or with glauca too. I found hybrid with Astroloba corrugata - see photo below.
H. beanii, form described by Smith, is recognized as separed species by Ingo Breuer. Ingo has also described H. viscosa var. variabilis from Brandekraal and surrounding area (see separed article).


H. viscosa is an easy species, which can be easily propagated by offsets or stem cutting. It is not much popular in collection, but if it is grown properly, H. viscosa is a very handsom species.

This sure does put me in mind of a Crassula! Very pretty growth pattern!

Dobrý den. Už dvacet let pěstuji rostliny pod označením Haworthia tortuosa, vůbec nevím kam ji zařadit, někde se uvádí že jde o synonymum druhu viscosa jinde se uvádí jako H.tortuosa. Na některých fotkách zde je určitá podobnost, dokonce jsem se ve starší literatuře dočetl že původ druhu tortuosa není znám. Jinak - viscosa je překrásná!Krásné snímky, výborný blog. Petr Hartig

Zdravím, H. tortuosa je zahradní kultivar = hybrid, zřejmě H. viscosa X s něčím...
