Gratiola Viscidula originates from Northern America and is relatively new to the aquatic hobby. The somewhat ‘thorny’ appearance of the submersed form makes it very distinct and easily recognizable.
It is quite easy to grow and prefers good light. By regular trimming, it can be kept very low, almost carpeting, but will also present itself well as a fore/mid-ground cushion-plant.
Each stem is approximately 1-2 cm wide and can become 10+ cm tall. The stem willingly branches and spreads giving a very dense appearance to the plant.
