This research program was initiated in 1999 as part of an SDSU Agricultural Experiment Station funded program in the laboratory of Dr. R. Neil Reese. This project is designed to provide research and educational opportunities to students interested in conservation and utilization of native plant species, as well as encourage the use of native plants by small family farmers as alternative crops in South Dakota.

Vitaceae : Vitis riparia
R. Neil Reese
Vitis riparia is a perennial viny shrub with stem growing to 25 m in length. The young branches are green to a dull reddish brown and the older stems are woody with exfoliating bark. The simple, alternate leaves have smooth petioles up to 8 cm long. The blades are 7-20 cm long and nearly as wide, shallowly to deeply palmately lobed. Leaves on fertile branches usually have 3 major lobes with a broad gaps between the 2 basal lobes. The leaves on vegetative branches are more evenly divided. The margins are hairy and sharply toothed. The inflorescence consist of pyramidal panicles 4-12 cm long, opposite the leaves of this year's new branches. The plants are monoecious, separate male and female flowers are typically on the same plant, mixed in a cluster or separate, tiny with 5 green to yellowish petals that drop without expanding. The male flowers have 5 long, erect to ascending stamens. The female flowers have a short style and 5 short sterile contorted stamens. The fruit are purple black berries, 7-11 mm in diameter. Riverbank grapes bloom in May and June with fruit ripening in July through September. They are found along streams, fence rows, in woodlands and ravines throughout South Dakota.
