The genus Agastache seems to have originated as a North American/trans-Beringian offshoot of its radiation about 25 million years ago, in the Late Oligocene. These three lineages form a tight-knit radiation as of 2016, it is not resolved with certainty which of the other two lineages is the sister taxon of Agastache, but most data place the aromatic group slightly closer. By contrast, the other lineage unites the largely scentless and low-growing genera Glechoma and Meehania which occur widely across the Holarctic. The closest living relatives of Agastache are believed to be two very different lineages: One is a group of mostly Asian and usually strongly aromatic and rather robust plants, which contains the typical dragonheads ( Dracocephalum), true hyssops ( Hyssopus), West Asian dragonheads ( Lallemantia), and Japanese catnip ( Schizonepeta). Agastache nepetoides anatomy note the curving stamen stalks typical of Agastache sect. The Nepetinae are robustly supported by cladistic analyses of morphological and DNA sequence data, and were recognized as early as the mid-late 19th century. Within its subfamily, it belongs to the mint tribe ( Mentheae), and therein to the catmint subtribe ( Nepetinae). It is a member of subfamily Nepetoideae, which contains a large proportion of the world's aromatic culinary herbs. The genus was established in 1762 by Jan Frederik Gronovius in the second edition of his controversial Flora Virginica, based on the specimens and notes of John Clayton. The flowers are usually white, pink, mauve, or purple, with the bracts that back the flowers being of the same or a slightly contrasting color.Īgastache derives from the Ancient Greek words ἄγαν ( ágan) "very much" and στάχυς ( stákhus) "ear of grain", describing the flower spikes. Upright spikes of tubular, two-lipped flowers develop at the stem tips in summer. Most species are very upright, 0.5–3 m tall, with stiff, angular stems clothed in toothed-edged, lance shaped leaves ranging from 1–15 cm long and 0.5–11 cm broad depending on the species. The common names of the species are a variety of fairly ambiguous and confusing " hyssops" and " mints" as a whole the genus is known as giant hyssops or hummingbird mints. It contains 22 species, mainly native to North America, one species native to eastern Asia. non Adans.: preoccupiedĪgastache ( / ˌ æ ɡ ə ˈ s t ɑː k iː/) is a genus of aromatic flowering herbaceous perennial plants in the family Lamiaceae. Cold hardy to -10☏ when protected from windchill.Lophanthus Benth. We recommend placing them about 18" apart. It can grow as tall as 18" and about 16" wide. It is both heat and drought tolerant once established. Mango requires well-draining soil and loves full sun. This plant is easy to grow, and you can remove spent blooms before they seed to prevent self-sowing, or leave them intact to attract birds to your garden or landscape. Its green foliage is nicely aromatic all summer long, yet it is surprisingly resistant to both deer and rabbits. It is aptly known as Hummingbird Mint, as it is very attractive to hummingbirds, as well as butterflies. Also known as Anise Hyssop, this special perennial is an excellent choice to bring vibrance to borders, beds, patio planters, rock gardens, floral and dried arrangements, and slopes. Blooms show throughout summer and into fall, but the calyxes last well after the blooms have spent, making for an ongoing attraction and protracted character. The bright orange-peach blooms of Mango Tango against the dusky-magenta calyxes add an incredible dynamic to gardens and landscapes alike.
