I first saw Crinum Natans at the Aquatic Gardeners convention in 2008. I instantly bought one in the auction the next day.
Here’s the deal with Crinum Natans. They have thick almost rubbery leaves kinda like an Anubias, only they are long and flowing.
Crinum don’t like to be moved, like most onion like plants, but once settled in, they get really sweet.
I have always kept them in a dirted substrate and I can tell by both their thick roots, and the growth that I have seen that they are heavy root feeders. You will want to treat this plant almost like the feeding conditions of an Amazon Sword.
Can’t tell you how they do in a non- dirted tank only because I have never tried it.
The plants i am selling are currently in sand over dirt substrate out in the greenhouse. They are getting blasted with sun.
(the Crinum I am selling are like 7 inches and have half inch wide leaves)
I don’t really care if I sell any of them as I want to see what 10 of them growing in full on sunlight together will look like.
What makes me so excited about the plant is just how giant they get once rolling. I originally had my Crinum Natans in my upper 75 under decent light. I have since moved it to my 220 where its leaves at one point were over 4 feet long if stretched out.
Don’t be afraid that it will out grow your tank, (it might but) you can cut back Crinum Natan and it will shoot off more leaves out the center of the tank, making in look even sweeter…
