Utricularia alpina x endresii

This Utricularia alpina x endresii was received from Mike Wilder on 13 January 2012. I planted it in an undrained 1.75 liter plastic bottle filled with live sphagnum and placed it in a west facing window in my house. The plant grew slowly and began flowering in November 2012. The photos below were taken on 30 November 2012 and 29 December 2012.
