Utricularia

All of my Utricularia are grown as windowsill plants at an east facing window. The humidity is quite low but most of the plants grow well.

Utricularia alpina

This plant is grown in pure live sphagnum. My impression is that the tricks to get it to flower are lower temperatures in winter and letting it grow undisturbed in the same pot for some years.

Utricularia humboldtii

Ut. humboldtii grows in pure living Sphagnum. In peat based subtrat mixes the same clone stays much slower and smaller.

Utricularia reniformis

This plant flowered in spring after colder winter temperatures and again after the very hot summer in fall. As compost I'm using my standard Nepenthes mix. Pure Sphagnum didn't suit this clone which grew massive amounts of stonlens but no leafes in this subtrat.
