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 recognisable. It is quite easy to grow and prefers good light. With 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 1-2cm wide and can become just over 10cm tall. The stem willingly branches and spreads giving a very dense appearance to the plant. Tropica 1-2-Grow Tissue Culture PlantsSmall plants with great success. Tropica 1-2-Grow are very young tissue cultivated plants grown in the Tropica laboratory. The plants are guaranteed to be free from snails, algae and pesticides and therefore are totally harmless for sensitive shrimp and fish. The 1-2-Grow range offers a unique range of plants. Success with your aquarium depends largely on the proper plant choice. Tropica 1-2-Grow plants offer a myriad of plants which can be divided into smaller portions to cover a larger area. Plants are compact from the start so you will experience dense and beautiful growth, if you provide them with the correct fertiliser and CO2 from the start. The range is perfect for small and medium sized aquariums. Tropica 1-2-Grow Directions Carefully remove the plant from the cup and rinse off the growing media. Split the plant as required into 6-8 portions using your fingers or sharp scissors. Plant portions into the substrate using tweezers. Then watch them grow!
