This versatile, pollinator-packed woodland perennial is a powerhouse for shady spots, producing striking, tiered pagodas of pale purple to white blossoms through the heat of the summer. It earns its descriptive name from the soft, downy hairs that coat its square stems and lush green leaves, giving the foliage a unique frosted appearance. When brushed against or crushed, the leaves release a rich, aromatic scent reminiscent of oregano and mint.
