Sticky Geranium (Geranium viscosissimum) is an attractive native geranium featuring foliage of 5-7 sharply toothed leaflets and charming 5-petaled pink or purple flowers. The plant gets its name from the sticky, glandular hairs that cover the leaves and stem. It is also protocarnivorous, able to dissolve the proteins from insects trapped on its sticky surface and absorb the nitrogen from this protein. Sticky Geranium is an excellent choice for garden beds and borders, cottage gardens, woodland and shade gardens, underplanting small trees or larger shrubs, or natural prairie or meadow plantings. The flowers are edible and can be added to salads or used as a garnish. It is tolerant of urban pollution.
