1 inch x 1 inch plug of the species Utricularia bisquamata ("Big Purple Flowers" clone). This species originates in Africa. "Big Purple Flowers" clone has very colorful flowers (see the image) which are a bit bigger than the typical U. bisquamata. At only 1 cm, bigger is a relative term!
Grows in wet areas, with occasionally standing water. Easy to grow, U. bisquamata can become a weed in collections. This clone - not so much. Grows in any of the standard CP mixes, we have had good results with 50:50 peat:sand. Keep it warm and give it pure water and plenty of indirect light.
