The Sphagnum cuspidatum is a very special species. Its leaves are very thin, like little needles, giving the plant a "pointy" look. This characteristic is due to an adaptation to aquatic growth. When it is immersed in water, the leaves open in all directions and give the plant an very similar appearance to that of a typical water plant. It can grow completely submerged during the whole year, forming heads “cushions” that emerge from the surface. This species is extremely resistant and invasive, but at the same time it does not form very voluminous “cushions”. For this reason it is especially suitable for growing small slow-growth plants (Drosera, Pinguicula, Utricularia, Seedlings).
