Crinum calamistratum Bogner & Heine

Narrow Crinum, Water onion

Crinum calamistratum is an African onion plant with resistant crepe leaves, which is not often found on the market.

The cultivation is not very difficult, a soft to medium water hardness and an almost neutral pH are suggested. The rich in nutrients substrate must be at least 8 cm high. A strong movement of the water encourages the growth. This species doesn’t grow fast and normally takes several months to become quite robust.

Distribution area: Central Africa.

Aquarium equipment

Crinum calamistratum is suitable only for aquariums at least 50 cm high. In fact, the plant growth is slow, but the leafs can reach more than 100 cm.

Plant care

The substrate material, at least 8 cm high, must be rich in nutrients (for example a clay-based additive). A strong movement of water will favour growth.

Water care

Soft or medium hardness water are suggested.
