Family

Botanical Name

AGASTACHE rugosa f. albiflora

Plant Common Name

Giant White Hyssop

General Description

An aromatic, erect, herbaceous perennial native to Korea, China and Japan, this member of the mint family bears spikes of white flowers in summer and autumn. The flowers attract butterflies, moths, and hummingbirds. The anise scented leaves are often more silvery than those of purple-flowered forms of A. rugosa. The cultivars 'Alabaster', 'Honey Bee White', and 'Liqourice White' are sometimes included under this plant.

This low-maintenance and drought tolerant plant likes well drained soil and full sun. It is an excellent choice for sunny mixed borders and wildlife gardens and does well in containers. It may self-sow abundantly.
