Kankakee Mallow
A tall pink-flowered mallow known from one small Kankakee River island survives through disturbance, seed longevity, and unusually focused conservation.
Artwork inspired by Pauline Palmer
Kankakee mallow grows tall stems with maplelike leaves and rose-pink, five-petaled flowers from a persistent underground crown. Its seeds can remain dormant for years, and the plant may respond vigorously when fire, clearing, or soil disturbance reopens shade. Apparent disappearance in a single season therefore does not prove extinction.
The wild population’s tiny island range makes it exceptionally vulnerable to canopy change, invasive plants, flood events, trampling, and unauthorized collection. Langham Island is a protected nature preserve, not a flower-viewing garden. Learn the plant at authorized programs or cultivated conservation collections, and never use a precise bloom report to justify off-trail access.
- Wild range
- One Kankakee River island
- Bloom
- Mostly July–August
- Leaf
- Maple-shaped
Quick guide
- Learn the silhouette
- Use tall branching stems, palmately lobed leaves, and hibiscus-like pink flowers together.
- Expect irregularity
- Fire, shade, flood, and dormant seed mean abundance can change dramatically between seasons.

- Expect irregularity
- Fire, shade, flood, and dormant seed mean abundance can change dramatically between seasons.
- View through stewardship
- Choose an authorized program or cultivated conservation planting rather than entering protected habitat.
- Keep locations coarse
- Do not post exact plants or collect flowers, leaves, fruit, or seed.
Good to know
The only natural population occupies a protected island and is not a casual public flower patch. Do not boat over, leave trails, collect seed, or circulate exact plant coordinates. Bloom abundance varies with management and disturbance; a responsible encounter may be a guided program or cultivated conservation specimen.
