  2. Deeply Lobed Leaves: Leaves are palmately divided into five or seven lobes.
  3. Small Pink to Purple Flowers: The flowers are small, with five petals and are typically pink to purple in color.

Cultural Uses:

Small-flowered cranesbill is often cultivated as an ornamental plant in gardens and landscapes. It is appreciated for its low-maintenance nature, attractive foliage, and delicate flowers.

Ecological Significance:

In its native and introduced ranges, Geranium pusillum can be found in a variety of habitats, including woodlands, meadows, and disturbed areas. It can play a role in providing habitat and nectar for pollinators.

Management:

While Geranium pusillum is generally not considered invasive, it may self-seed and spread in favorable conditions. If control is needed, manual removal of unwanted plants or cutting back spent flowers before seed production can help manage its spread. In cultivated settings, it is advisable to deadhead (remove spent flowers) to prevent self-seeding.
