   Giant Vallisneria are a great plant for tall aquariums since the leaves can grow up to 39 inches long!

   The leaves of the Giant Vallisneria are dark green with rounded tips. They generally grow in cycles, thriving for 3 or 4 months and then dying off for another few months.

   Giant Vallisneria do well in a mixture of fine sand with a medium light level. The leaves may grow up and across the surface of the aquarium so watch that they don't overshadow the lower levels of your aquarium. Iron is important for these plants, and the best way to ensure that they get the right quantities is to use an iron-rich substrate.

This plant seems to need lots of light. In my tall narrow triangular tank it grew well at the front - I didnt know it has a few months dormancy and threw it out. i have re-purchased but its at the back in a dark corner and not doing well at all. allan 2005-01-23
I have collected plants indistinguishable from giant vallisneria in streams and lakes in Minnesota. They seem to do better than the vals I’ve bought. Previous vals always died in a few months. These collected ones have prospered for a few years, spreading by shoots and blooming continuously. I have to trim them every couple of weeks to keep the water surface open. I have a tall aquarium but the leaves grow about four feet long. John Breczinski 2005-01-04
i have one of these that just takes over the aquarium. it breeds ferociously and even when i take it out of the aquariun it just pops up with new ones. i want to control it better with a social fish that could eat the plant and help keep it under control. heather levin 2004-08-10
