Utricularia intermedia

Flatleaf bladderwort

A small, rootless, submerged bladderwort of cool-temperate fens, bog pools and peat cuttings right across the Northern Hemisphere. It has two kinds of shoot: green shoots with flat, trap-free leaves and pale shoots pushed into the soft bottom that carry the bladders. It dies back to winter buds (turions) each autumn, so it needs a cold winter rest and clean, nutrient-poor, neutral to slightly alkaline water.

Where it grows wild

Shallow, clear, still water in fens, bog pools, peat cuttings and ditches, usually oligotrophic to moderately nutrient-rich and neutral to slightly basic. The plant lies anchored among sedges and mosses on a soft organic bottom, with trapping shoots buried in the mud and green shoots in the water column.

Mainly a lowland to montane plant of temperate and boreal regions; no elevation band was available from the sources consulted.
