Stachys recta grandiflora

Stiff hedge nettle (looks only). This is a short Stachys, only 20-40 cm tall, with a stiff and neat habit. Like all the other Stachys species this plant produces abundant nectar and pollen therefore the white-cream flowers with purple markings are constantly foraged by pollinators of all kinds. Good for the edge of the flower border, in the wildflower meadow or at the margins of the woodland garden.
