Aquatic bulb plants have a great variety in aesthetics and prices. We currently carry the Aponegeton Natans species in our stock bulbs which are quite beautiful yet hardy. If you are interested in buying some bulb plants online check out our inventory.


There exists many types of Aponogeton ulvaceus, a number of which require a dormant stage where the roots dont create leaves. Most plants within the aquatic market become hybridized. And therefore the majority of those hybridized varieties want a dormancy period; but, it seems that the plants that have purple / lavender blooms don't require this.
Aponogeton ulvaceus could be a fairly forgiving plant. It will survive in low lighting with marginal fertilization, however requires high lighting if you want its full beauty and to bloom. With high and intense lighting will grow as much as 6 inches / 15 cm during a single day! Its fairly tolerant, and thrives in soft and hard water, especially if CO2 is supplemented. Read the CO2 Use in the Planted Aquarium article for more information.


Forced Dormancy
When the plants slows in growth and begins to wither, take out the bulb from fish tank. Remove all leaves and roots. Place bulb into a cup of cold water. Leave the cup in a cool place for a month or so. Then put the bulb back in to the tank and surround the bulb with substrate that has fertilizer.
