About

Agastache rugosa f. albiflora is a clump-forming perennial that typically reaches heights of 1 to 1.5 meters. Its upright stems support pointed, hairy leaves that can grow up to 10 centimeters in length. During the summer season, the plant produces dense, terminal spikes of hairy white flowers, each measuring around 10 centimeters long.

About the genus

Agastache consists of herbaceous perennials featuring straightforward, fragrant foliage and small tubular flowers with two lips, arranged in whorls that create compact spikes during the summer and autumn months. While some species may be somewhat tender, they can also be cultivated as annual bedding plants.
