Isodon longitubus / Akichouji アキチョウジ

Isodon longitubus, a perennial found in the shade of a tree in mountainous regions, grows to 70-100cm in height, with stems a cross-section of a square with downward hairs of ridges. Blades measure 7-15cm long, 2.5-5cm wide, long oblong, with sparse hairs on surfaces, with bases becoming cuneate-like wings to follow petioles. Stem tips and axils generate slender spikes and arrange flowers one-sidely on them; upper lips cleft themselves in three with the lobes obtusely triangular and lower lips shallowly cut in two, obtuse. Corollas are blue-purple, 1.2-2cm long, and the basal portions expand. Bloom time: September-October.
