1 inch x 1 inch plug of the species Utricularia warburgii. This species originates in Zhejiang province in eastern China. Very colorful flowers (see the image) which are very small. Grows in wet areas, with occasionally standing water. Grows in any of the standard CP mixes, we have had good results with 50:50 peat:sand. Easy to grow, but can be challenging to get it to flower. Our occasional successes have been with plants grown in a greenhouse, with seasonal temperature fluctuation from low 50 deg F. in the winter months, to upper 80s to low 90s in the summer. The plants which produced flowers were in non-draining containers and were submerged in water at the time, in early summer. Keep it warm and give it pure water and plenty of indirect light.
