Agastache Gronov.

Agastache is a genus of ca. 22 species. All but one are native in North America (a single species in eastern Asia). Several species of the genus are cultivated as ornamentals. Whiteley (2000) cites eight species for European gardens but only a few are more or less widespread. In the past years Agastache has become popular in Belgian horticulture as well but mainly as pot plants.

The identity of plants in cultivation is rarely straightforward. Most garden plants probably are cultivars or hybrids of obscure parentage. Those found in Belgium so far seem to be mostly referable to Agastache rugosa or hybrids/cultivars of it.

Molecular data demonstrated that Agastache forms a distinct clade (e.g. Kaufmann & Wink 1994).
