Geranium maculatum has several common names: Wild geranium, spotted geranium, crane's-bill. It is a common woodland native herbaceous perennial plant that blooms in spring.

Flowers

The flowers are lavender-pink and about 1 to 1.5 inches wide. The 5 petals have radiating streaks which guide insects to the nectar. There are 5 hairy nectar glands between the bases of the petals.

There are 10 stamens in 2 whorls of 5. The anthers are yellow and turn brown with age. The 1 pistil is formed from 5 fused carpels. A carpel each has an ovary, a style and a stigma. So there are 5 of each.

The 5 sepals have non glandular hairs, and have spine-like tips.
