Maple Mallow, sometimes known as Mountain Hollyhock, (Iliamna rivularis) is a beautiful Utah plant that looks similar to more traditional garden Hollyhocks. This tall perennial features large, open, rose-pink flowers from summer to early fall. Maple Mallow establishes easily and freely reseeds itself, so make sure to choose an appropriate planting site where this can be allowed. This plant makes a stunning addition to the back of garden beds, borders, or cottage gardens, natural meadow plantings, or the edge of shaded and woodland gardens.
