Viburnum cassinoides L.
Common Name: WILD-RAISIN
Coefficient of Conservatism: 6
Coefficient of Wetness: 3
Wetness Index: FACU
Physiognomy: Nt Shrub

A tall shrub of diverse usually wet ground: peatlands (fens, bogs, cedar swamps, boggy forests), forested tamarack, red maple, deciduous swamps; moist areas or even drier sites in oak, pine, or jack pine forests, usually in more acidic and often sandier soils than V. lentago.

In much of Michigan, this is one of our commonest viburnums of moist places, and of our three common wetland viburnums, this is the latest to bloom, usually overlapping the last of V. trilobum, which in turn may overlap the last blooming of V. lentago.

The immature fruit is red or whitish, though it may turn a handsome glaucous blue when dried. Leaf tips vary from acute to rounded to short-acuminate. The petioles and branches of the inflorescence are usually densely scurfy with rusty-orange scales. Such scales are sparse or absent in V. lentago and V. prunifolium.

Some authors include this taxon in the southern and eastern V. nudum L., as var. cassinoides (L.) Torr. & A. Gray.
