Frequently asked questions
Is it really a crassula?
Yes — the small flowers and the family resemblance confirm it despite its conifer-like appearance.
Best for terraria?
No — terraria are too humid for this dry-loving succulent. Use it on a sunny windowsill or in a small dish garden.
How fast does it grow?
Slow. Mature plants stay 15 to 30 cm tall and add only a few cm per year.
