Marshmallow root (Althaea officinalis) is a perennial herb that’s native to Europe, Western Asia, and Northern Africa. This erect, very rarely-seen, British native wildflower will thrive in damp conditions and gives a lovely late summer display of multiple soft pink flowers, (which occasionally are pure white with pink anthers!) on tall softly hairy stems with attractive grey-green leaves. It is an herbaceous perennial and so will return for several years after dying back over winter.

Sow immediately at any time onto preferably a soil-based compost, covering with fine grit to approximately their own depth. Germination MAY be quicker if kept at 15 to 20 degrees C. but many seeds WILL NOT come up the year they are sown, needing winter chilling after sowing, and ONLY come up with natural spring germination.
