Who We Are

The Botanical Club of Wisconsin, the state's only organization dedicated to the study of our native flora, was founded in 1968 by John Thomson as an affiliate of the Wisconsin Academy of Sciences, Arts and Letters. The BCW serves the interests of amateur and professional botanists toward the common goal of learning more about our state's plant biodiversity.


Fall 2022 Events

Willow Workshop!

*Please note a state parks/forests pass is needed to park here*

Notes: Dan Carter, Landowner Services Coordinator for The Prairie Enthusiasts, will lead a workshop and hike about vegetative identification of willows (Salix). We will start by briefly examining and discussing vegetative material from several common native willows. Then we will head out to the sedge meadows, low prairies, and fens of the Scuppernong Habitat Area. There we will encounter some of the same willows and a few less common species. We are likely to encounter peach-leaved willow (Salix amygdaloides), Bebb’s willow (S. bebbiana), hoary willow (S. candida), pussy willow (S. discolor), Missouri River willow (S. eriocephala), blueleaf willow (S. myricoides), meadow willow (S. petiolaris), autumn willow (S. serissima), and maybe a few more. Some willows will be vexing, perhaps due to hybridization or depauperate growth over marl. There will also be plenty of non-willow flora along the way—Kalm’s St. John’s-wort, Ohio goldenrod, nut-rush, and much more. The water table should be low, so we ought to be able to keep our feet mostly dry (but you may want to wear rubber boots). Participation is at your own risk & after signing a participation agreement form. We will be traversing off-trail and in areas with well-developed tussocks, uneven terrain, the occasional poisonous plant, and amongst stinging & biting insects.
