This aromatic plant is gracing the Scented Garden with its blue flower spikes.
The genus Agastache is a member of the mint family, and bears square stems, opposite leaves and tubular, two-lipped flowers characteristic of the family. Containing approximately 30 species of aromatic perennials, the genus occurs in dry habitats of China, Japan, the United States and Mexico. All species form erect, bushy plants and have flower spikes bearing whorls of flowers. ‘Liquorice Blue’ produces erect spikes of purple-blue flowers, which are nectar-rich and highly attractive to pollinators. The individual flowers are held in whorls of contrasting pinkish bracts, and the flowerheads mature to create an attractive seed head. The leaves bear a close resemblance to those of nettles. When brushed, Agastache plants release a scent, and this has lead to the common name giant hyssop. They require full sun, good drainage and shelter in cultivation.
