Red bartsia (Odontites vernus) is a semi-parasitic annual wildflower that attaches to the roots of nearby grasses to supplement its nutrition. It thrives in open, nutrient-poor grasslands and roadside verges with minimal care. Best suited to wildflower meadow projects; avoid over-fertilising as rich soils reduce its vigour.
