Ah paw no gee ton
Aponogetons don't get discussed in forums that much any more. It is a plant genus that has been around in the hobby since its begining, but large plants are not as popular as they once were. Everybody knows them as the bulbs that come in those packs at Walmart, or the Madagascar lace plant that is unmistakable, but one specie I think that is often over looked is one with the longest name...
This species comes from madagascar and looks somewhat like its cousin "crispus" from Sri Lanka. Longiplumulosus leaves are generaly more narrow and much more wavy, fluted leaves. Growth goes dormant periodically, but will usually begin its growth cycle again within a few weeks without beeing removed or uprooted.
Like most Aponogetons, it often flowers on a long spike that reaches the water surface.
Moderate light is really all it needs. Regular feeding either via the substrate or the water column will insure continual growth cycles. C02 will speed the growth to maturity creating more of a demand for a nutrient reserve stored in the tuber to enable the plant to continue to the next growth cycle.
I just like the look and feel of the plant. As long as it's basic needs are addressed, it is a easy plant to grow and fine for a "low tech" enviornment in large tanks, or tall tanks.
