African onion plant, Cameroon crinum - Crinum Calamistratum is a unique looking plant that will grow long and flowing leaves once it's established in your Aquarium. Crinum Calamistratum is harder to get started but is great once established.
This plant requires an excellent, nutrient rich substrate. (Dirt is what I keep it in) Don't try to keep Crinum Calamistratum in plain old gravel.
