Gratiola viscidula – A Unique Grass-Like Aquarium Plant for Structured Aquascapes
Gratiola viscidula is a rare, grass-like aquatic plant that adds a distinct, structured look to planted aquariums. With its rigid, upright growth and bright green, spiky leaves, this plant creates a miniature underwater forest effect, making it an excellent choice for foreground and midground placement. Its compact, slow-growing nature allows aquascapers to design intricate layouts with minimal maintenance.
Hardy & Easy to Maintain
Unlike many delicate foreground plants, Gratiola viscidula is hardy and adaptable. It thrives in moderate to high lighting and does not require CO₂ supplementation, although added CO₂ and nutrient-rich substrate will encourage faster, denser growth. This makes it a great option for low-tech and high-tech planted tanks alike.
