Hackelia deflexa is a vascular flowering plant in the borage family known by the common names, northern stickseed[2], nodding stickseed[3], and American stickseed[4].
It is native in many northern locations from much of Canada and the Northern USA as well as in Europe (Spain, France, Italy, Austria, Romania, Ukraine, Russia, Sweden, Switzerland, etc.) and in Korea and Japan (where it is critically endangered).[5][6] It can be found growing in moist woods and thickets in habitat that is shaded, partially shaded, or sunny.[4]
Description
Average height: 2 - 3 ft (0.6 - 0.9 m)
Leaf color: green
Hackelia deflexa grows ovate basil leaves, which have stalks and rounded tips, while upper leaves grow progressively smaller, and stop developing stalks as they reach increased heights. Leaves can be 5 to 12cm long and up to just over 3 cm wide. They have a rough texture on their upper surface, and are hairy. Stem leaves grow alternately on erect single (generally) stems that are "much branched with short fine hairs throughout"[4], and are "narrowly lance-elliptic, tapered equally at both ends with a pointed or blunt tip"[4].
Bloom Color: light blue to white
Propogation: by seed
Hackelia, once it has flowered and been pollinated, produces a small nutlet with tiny prickly barbs on it. These barbs allow the nutlet to stick to animal fur and human clothing as it is brushed up against, thus allowing seed to be transported and dispersed as far as the unsuspecting traveller takes it.
