Sebastian, a Cereus Forbesi Spiralis, Cereus Peruvianous Tortulosus, Twisted Cereus, or Contorted Cereus, is well known for his shape, but believe it or not, he starts out life with straight ribs - in fact, it's not until Sebastian reaches around 10cm tall that he begins to twist!
Native to South Africa, his blue-green colour and tower-like form are almost alien-like, and if you're lucky enough to see him flower, they'll be pink or white with long delicate petals.
Sebastian, Cereus Forbesi Spiralis Cactus - Small
Sebastian prefers bright light and once established will even tolerate direct sun.
If you’re not sure what level of light you have, check the shadows cast by your plant:
- Minimal shadow = lower light
- Half shadow = indirect light
- Full shadow = direct sun
