About
Agastache breviflora is an herbaceous perennial in the Lamiaceae, valued for its aromatic foliage and long flowering season. It forms clumps with multi-stemmed, well-branched growth and greyish-green to bronze-tinged leaves. Flowering runs from July to October.

In the garden
Agastache breviflora originates from the south-western North American region, including Arizona, New Mexico, Texas and north‑eastern Mexico. As a member of the mint family it produces aromatic foliage that helps identify the plant even before flowers appear. The recorded flowering season in the UK runs from July to October, giving weeks of interest through late summer and into autumn. Give Agastache breviflora a sunny, south‑facing site where it will be sheltered from prevailing winds. It prefers a neutral‑pH loam that drains freely; avoid heavy, waterlogged ground. The hardiness rating H4 corresponds to average hardiness in UK terms, so a protected position in mixed borders, cottage gardens, wildlife schemes, city courtyards or flower beds will best preserve the crowns through colder winters. Position it where the aromatic leaves can be appreciated at close range and where the summer–autumn blooms are easily seen by pollinators. The plant’s clump-forming habit makes it straightforward to group with other sun‑loving perennials in beds and borders. Expect the scent of the foliage to be a reliable seasonal cue and the July–October flowers to extend colour later into the year.
