This is one of three common non-native mallows. Like Cheeseweed (Malva parviflora, see below), it is a small to medium sized shrub. Also, they both have 5-petaled flowers, pink to blue-violet, with darker pink veins and coarse, roundish to kidney-shaped leaves. This has petals about 2× as long as the calyx which itself is 4–6 mm long, larger when in fruit, and sometimes enclosing the fruit. Fruits are flattish with 7–10 segments. Bractlets are 4–5 mm, ovate to oblong.
