Who is the Narrow Crinum?

crinum calamistratum detail

This beautiful, very long plant has strong, curly, embossed and narrow leaves (only 2 to 4 centimetres or 1 to 2 pouce wide). The dominant colour is dark green.

Like most plants of the Crinum type, it does not have any particular maintenance conditions, which makes it a very easy plant to maintain.

This species of aquatic plant is very resistant to vegetarian cichlids!

Planting and maintenance

How to plant and maintain the Narrow Crinum?

In its natural environment, the Cirnum lives in rivers with strong currents. Thus, in aquariums, it will appreciate being installed near the pump outlet. Its long leaves will then spread over the entire surface of the aquarium.

Never bury the bulb of your Cirnum: it must remain above the substrate. Indeed, if it is buried, it will rot, causing the death of the plant.

For good growth, provide good lighting and nutrient-rich soil. A supply of CO2 is beneficial, but not essential.

For water parameters, don't worry, they are not very important for this very adaptable plant. Ideally start with a temperature between 22 and 26°C (72 and 79°F), rather soft water and a pH not too high, but again, these parameters are not critical.

On the maintenance side, be aware that this plant can become very tall. Moreover, some have been listed with a height of one meter! To prevent it from invading your aquarium too quickly, prune it regularly. Also, the oldest leaves will turn yellow over time. Remove them by cutting them off at the bulb when they turn yellow.

Tip: To extend the life of your plant, put it to rest once a year. Simulate the winter period by taking it out of your aquarium and storing it in a cooler one. Leave it in this aquarium for 2 months and then reinstall it in your main aquarium.

Cirnum calamistratum is cultivated by dividing the bulb. If maintenance conditions are good, it will give buds (bulblets). Detach the small bulbs at the base of the main bulb and replant them.

When it arrives at your home, your Water Lily may turn completely yellow. Do not throw it away! This is a normal reaction. The new leaves to come will be very green ;)
