Polecatweed is a unique native wetland plant that produces distinctive hooded flowers in early spring before large cabbage-like leaves emerge. It requires consistently moist to wet soil conditions and thrives in shaded areas near water features or low-lying spots. The plant gets its name from the strong odor it releases when bruised or damaged.

Growing Polecatweed

Grow Polecatweed in part shade and high water. Mature plants reach 12 to 24 inches tall and spread 12 to 24 inches wide. Expect low maintenance to keep it looking intentional in a front yard.

In an HOA neighborhood

Polecatweed takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.

Works well in: backyard only.

  • Strong unpleasant odor when disturbed
  • Very informal wetland appearance
  • Requires swampy conditions unsuitable for typical landscaping

Wildlife value

This plant attracts flies and beetles with its early spring blooms, providing nectar when few other flowers are available. The unusual flowering strategy makes it an important early-season pollinator resource.

Common questions

When does skunk cabbage bloom?
Skunk cabbage typically flowers from March through May, often pushing its mottled spathe up through late snow and frozen ground before the leaves unfurl.
What pollinates skunk cabbage?
Flies and beetles are the main pollinators. They are drawn to the flower's carrion-like odor and to warmth generated by the spadix during cold early spring days.
What kind of site does skunk cabbage need?
It grows best in part shade with consistently wet to saturated soil, such as forested seeps, streambanks, and boggy low spots.
Does skunk cabbage keep its leaves year round?
No. It is deciduous, with large cabbage-like leaves emerging after bloom and dying back by mid to late summer.
