I’m bending the rules again by featuring a European native rather than a plant endemic to Iowa. Bittersweet nightshade (Solanum dulcamara) can be found in most of the United States and Canada, especially “in the eastern and north-central United States, […] the upper Great Lakes states […] and the Pacific Northwest.” This “semi-woody vine” is sometimes known as climbing nightshade, wood nightshade, or European bittersweet. Like dayflower, it has become widespread in Iowa and many other states. Some people call such plants “nativized.”
Bittersweet nightshade is not on Iowa’s noxious weed list, unlike fellow European invader poison hemlock or Carolina horse nettle, a native North American plant. I’ve mostly seen this vine growing on fences at the edges of yards, rather than in unspoiled habitat. I took all of the enclosed pictures right here in Windsor Heights. Canadian photographer Brian Johnston has taken phenomenal close-up shots of Bittersweet nightshade flowers. Click through; you won’t be disappointed.
