In the garden
Molinia caerulea is a grass native to Europe and Asia that suits wetter sites where many other grasses struggle. It establishes on sandy, loamy or peaty soils and accepts a pH range from acidic to neutral, so it is a good choice where peat or naturally acid soils occur. In the UK it carries a fully hardy rating of H7. Position Molinia caerulea in full sun or partial shade and ensure the soil does not dry out; it performs best where moisture is retained or in regularly wet ground. The stated soil types — sandy, loamy and peaty — cover a wide range of wetter garden situations, while the acid–neutral pH tolerance means it will fit into both heathier, peaty borders and neutral wet meadows. Use it where seasonal flowering and a moisture-tolerant grass are needed: structural lines in naturalistic plantings, the damp edges of borders and established wet-meadow schemes are all appropriate. Expect its flowering season to run from July to September, so plant it where late-summer inflorescences will contribute to meadow and border sequences rather than early-season displays.
