This crypt is a time-tested, undemanding medium-green aquarium plant that forms a relatively low medium-green lawn after some time by growing runners. Its leaves are wider, and it grows much faster than the tiny Cryptocoryne parva. Its emerged form can develop leaves on very long stalks, under water they stay a lot shorter though. For a long time it has been popular under the erroneous name of “Cryptocoryne nevillii”, but today it is counted among Cryptocoryne x willisii. C. x willisii “lucens” looks rather similar, but Cryptocoryne x willisii “nevillii” has shorter more ovate leaf blades.
This Cryptocoryne is a very popular, undemanding, low-growing aquarium plant that reproduces through runners, forming nice ground-covering carpets. It was long known under the name “Cryptocoryne nevillii”, and sometimes still is. In 1976, Niels Jacobsen found out that it really belongs to the hybrid complex of Cryptocoryne x willisii.
