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.
Tissue culture plants are grown in-vitro (literally: in the glass) in a nutrient-rich synthetic growing medium, either liquid or gel, without the presence of any other lifeforms. This guarantees a pest and disease-free specimen, while also providing accuracy throughout the trade.
Tissue culture plants should be removed from the cup as soon as possible. All plants grow on some sort of synthetic growing medium, ranging anywhere from liquid to jelly to firm gel. This should be removed and rinsed off. Gently massage the roots between your fingers until the gel dissolves away. Most plants can be broken up into smaller pieces and spread out in your aquarium. Smaller pieces are easier to plant.
