FutureStarrA Agastache Scrophulariifolia
Individuals of this species are perennial herbs that can grow up to six feet tall. They are late-flowering species in the mint family. Agastache scrophulariifolia tends to have several spiked inflorescence. Flowers of Agastache scrophulariifolia do not all bloom simultaneously and range from lavender to pink in color. The dark brown fruit they produce is a nutlet. Agastache scrophulariifolia was once distributed throughout CT, DC, DE, GA, IA, IL, IN, KS, KY, MA, MD, MI, MN, MO, NC, NE, NH, NJ, NY, OH, PA, SC, SD, TN, VA, VT, WI, WV, and ON, Canada. However, its range is now severely reduced in many areas and in some cases extirpated completely. These declines are largely due to habitat loss, predation by deer, and competition for resources with non-native plants.
Agastache scrophulariifolia is ranked S1 by the Georgia Department of Natural Resources, indicating that the species is critically imperiled in Georgia. Eight populations in five counties are known although only 3 have been seen since 2000; half occur on the Chattahoochee National Forest, the others on private land.The flowers are 5-parted, the corolla is whitish to purplish and exceeds the calyx in length. Flowers are not hairy. The corolla has an upper lip, formed by two fused petals and divided into 2 lobes which turn upward and a lower lip formed from 3 fused petals divided into 3 lobes that turn downward. The calyx, with 5 long pointed lobes, is green to whitish-purple compared to Agastache foeniculum where it is purple. There are 4 long stamens in pairs with white filaments and a style, all protruding from the corolla. A pair of stamens curve upward and a pair curve downward.
Names: The genus Agastache is derived from two Greek words - agan, meaning 'very much' and stachys, meaning 'an ear of wheat' which together refer to the flower spikes of this genus having many flowers, like grains of wheat. The species name scrophulariifolia, is a reference to the leaves of the Scrophularias, (figworts) whose leaves resemble the leaves of this plant, that is, somewhat deltate shape with coarse teeth. That led to the alternate common name of 'Figwort Giant Hyssop.' Comparisons: A similar looking plant but shorter, and whose flowers have a purplish calyx is Blue Giant Hyssop, A. foeniculum. It also tolerates slightly more dry soils and spreads by reseeding. Another is Yellow Giant Hyssop, Agastache nepetoides, which is also tall, branched, but with yellow flowers and a catnip odor. Much like no. 1 [Agastache nepetoides (L.) Kuntze]; lvs glabrous to villous beneath; spikes cylindric or tapering, to 15 cm, 1.5-2 cm thick (including the cors); bracts round- ovate, caudate-acuminate, often projecting; cal 7-9 mm at anthesis, the lobes 2-2.5 mm, lance-triangular, with straight or concave sides, sharply acute or acuminate; cor purplish.
