Taxiphyllum 'Spiky'Spiky is Asiatic and grows 2 10 cm tall. Best described as Christmas moss' big brother, it is bigger and forms many deep green, branched shoots. Spiky moss does best on vertical surfaces where the branched shoots will show. A beautiful carpeting effect is possible if you plant small tufts into the bottom substrate with a small interspace. It grows fast and thrives at a very low light intensity.
