Lobelia urens


A rhizomatous perennial herb of rough pastures and grassy heaths. It is confined to infertile acidic soils that are often seasonally waterlogged. Reproduction is by seed, which may be long-lived, and germination seems to be stimulated by disturbance. Most populations fluctuate erratically in size. Lowland.
