Rhinanthus minor. Annual. Attractive, partially parasitic annual. It is a semi-parasitic plant which means that by using haustoria (root-like organs) it can absorb water and minerals from neighbouring plants.
This will often reduce the vigour of adjacent coarse grass , helping wild flowers to flourish . Each patch triggers succession allowing other species to establish in the resultant vacant areas. Flowers April to July. 300 seeds per gram.
