Betony (Betonica officinalis, formerly Stachys officinalis) produces dense basal clumps of scalloped, deep green leaves. On ‘Alba’, clusters of bright white flowers appear at the top of upright, 18- to 24-inch-tall stems in early to midsummer. If you aren’t planning to collect seed, I suggest shearing the whole plant to about 1 inch above the ground once the flowers are finished; the plants will then produce a tidy mound of fresh leaves that look good through the rest of the growing season. Full sun to light shade. Perennial; Zones 4 to 8.
2021-collected seeds sold out. I hope to collect again in late summer 2022. At least 15 seeds.
Please read the germination information as well before ordering.
