Lamourouxia virgata

Commonly referred to as Purple Toothwort, this parasitic plant is devoid of leaves and poses no harm to its hosts, which include species like Willow, Poplar, Hazel, and Alder, along with various ferns, herbs, and other trees. It remains largely unnoticed for most of the year, emerging from April to June when it produces glossy, predominantly dark violet-purple flowers, occasionally displaying lighter hues, resembling crocuses. The plant has a unique method of dispersing its seeds explosively, enabling it to spread over distances of up to 8 meters. For additional details, visit the RHS podcast at

Melampyrum nemorosum

Melampyrum pratense is an annual wildflower indigenous to the British Isles, particularly abundant in the western and northern regions. It features slender, erect stems that can reach heights of approximately 50 cm, adorned with narrow, pointed leaves that serve as a food source for the caterpillars of the heath fritillary butterfly. From late spring to early autumn, primarily during summer, the upper part of the stem showcases narrow, tubular yellow flowers arranged in widely spaced pairs. These blooms attract bees and also provide nourishment for the caterpillars of the lead-coloured pug moth.

Melampyrum pratense

Melampyrum pratense subsp. commutatum is an annual wildflower indigenous to the British Isles, with a preference for southern regions. Its slender, upright stems can reach heights of approximately 50 cm and bear narrow, pointed leaves that serve as a food source for the caterpillars of the heath fritillary butterfly and the lead-coloured pug moth. From late spring to early autumn, the upper portion of the stems features pale yellow, tubular flowers arranged in loose pairs, with peak blooming occurring during the summer months, attracting bees with their nectar.
