Melampyrum pratense subsp. commutatum

Annual Biennial

A native, annual wildflower, found throughout the British Isles but favouring the south. Slender upright stems to about 50cm carry narrow, pointed leaves that are food for heath fritillary butterfly and lead-coloured pug moth caterpillars. Narrow, tubular, pale yellow flowers are carried in widely spaced pairs on the upper half of the stem from late spring to early autumn, peaking in summer and providing nectar for bees

How to Grow

Cultivation

This, less common, subspecies occurs on chalk or limestone soils in scrub, hedgerows or deciduous woodland, favouring well-drained soil in a sunny or part-shaded position. It is a hemi-parasite, meaning it can photosynthesise but also derives some of its nourishment by parasitism, probably on the roots of woody plants. Consequently, it is likely to be difficult to establish away from its natural environment

Propagation

Naturally propagates by seed, often spread by wood ants
