One of many vallisneria variety. A common problem when planting vallisneria sp is the leaves initially tend to break off. This is normal as the plant is acclimating from the great stress of being transported and re-planted. Watch out for K and Ca deficiency as the leaves are prone to develop holes and tears when lacking of minerals. Once it settles in, the gigantea variety grow very tall. Pruning is by cutting the excess top part. Propagate from runners. Do not severe from the motherplant until it reached usable size.
Contrary to popular belief, Jungle Val will not melt with regular excel dosing. It will however melt if you suddenly start using excel, and do not keep up with regular daily dosing. It's vulnerable to spikes, but flourishes with regular use.
Jungle Val is a lovely and extremely large plant. The leaves exceed 5 feet long. It spreads quickly and easily. It is relatively herbivore safe, tinfoil barbs don't eat it. On it's own it spreads in straight lines (until an obstacle is met)
This is probably one of the best beginner plants. It grows extremely quickly, and can get extremely tall. I have an entire forest of Vals in my 46 gallon tank, and many of them have their leaves bending at the surface of the water. This huge forest came from only a few small plants a few months ago. A nice thing about Vals is that in moderate or high light, some of their leaves turn a lovely shade of orange or red.
A wonderful beginner plant; it looks very exotic. I may be misidentifying, but I've found plants that look identical to Jungle Val growing in the NH lake where I swim, and I've kept some in my lily pond. Very easy plant for covering filter intakes, etc., but leaves will grow to the water surface and bend over covering the whole tank unless you give it frequent haircuts. Edit: I am quite certain the plant from my local lake is Vallisneria Americana. Don't know about the "gigantea" part, but it grows just as big for me. I won't be paying for this plant in the future! It's widely distributed over North America -- so much for the "Jungle" mystique. http://plants.usda.gov/java/profile?symbol=VAAM3
Grow, grow, grow! It never stops yo! Seriously, these leave never stop growing, but rough handling does end in them being broken. Clean cut the tops of these leaves with scissors to avoid rotting and likewise plant so that the root are just showing out of the substrate. This will allow new leaves and clones to grow from the base unobstructed by substrate. Nobody like ingrown hairs, let alone ingrown vals.
A good choice for a low tech tank. A nutrient rich substrate is more important than high lighting at least in my experience because this plant has an extensive root system. Relatively fast growing in the right conditions. Sooner or later, you will find yourself with more than enough of these plants. It can also easily grow tall, so make sure it does not shade your other plants.
Has anyone ever had an issue with this plant dying if in too warm of water. I recently had to treat my tank with Metro and I raised the temp to 88 degrees. Now my Val have all withered up, the green is gone, and they are breaking off.
