Plant Description:
Name:small flower geranium
Scientific Name:Geranium pusillum
Family:Geraniaceae
Type:Broadleaf
Lifecycle:Winter Annual
Habit:Smallflower geranium are usually found growing in pastures, turf, or disturbed sites. Seeds germinate in fall and spring and grow through the winter to bloom in early summer. Flowering occurs from April until July. Above-ground foliage dies back during late summer. Plants may act as biennials and are often found growing from a taproot.
Leaves:Leaves are rounded and hairy on both surfaces. Leaf clefts or lobes are rounded and shallow giving the leaf an overall round shape. Leaves are born on long petioles. Leaves form a basal rosette when plants are young.
Leaf Arrangement:Alternate
Characteristics: Smallflower geranium is similar to dovefoot geranium except that the carpel body of dovefoot geranium is smooth and that of smallflower geranium has very short hairs. Carolina geranium and dissected geranium differ in that their leaves are deeply dissected, sepals have long awn-like tips, and carpels are covered in hair (gland-tipped in dissected geranium).
Flower Seed Head:
Flowers are produced in clusters of one or two where stems terminate. Flowers are pale pink and sepals have a sharp point but lack the longer awn-like tip of Carolina geranium and dissected geranium. The carpel body is covered in fine short hairs.
Seed Fruit:
Fruit have long beaks and the carpel body is smooth. Seed are smooth.
Where Found:
A weed of lawns and pastures, smallflower geranium can be found in mountains and piedmont areas.
