Flowers - To 1.5cm broad. Petals 5, white, distinct, glabrous, to 7mm long, +4mm broad, short-clawed. Stamens many, borne at edge of hypanthium, spreading. Filaments to 2.5mm long, glabrous, whitish. Anthers yellow, .5mm in diameter. Carpels many. Styles persistent in fruit, elongating to 7mm and with 2mm deciduous portion in fruit. Sepals lance-ovate, acute to acuminate, to 5mm long, 2.5mm broad at base, pubescent externally(with whitish tomentose margins), glabrous internally, spreading to reflexed.

Geum canadense flower

Geum canadense fruits Fruits.

Flowering - May - October.

Habitat - Moist wooded areas, wooded slopes, thickets.

Origin - Native to U.S.

Other info. - This is a very common woodland plant in Missouri. Although it can be considered weedy, I think the flowers are quite nice.
Steyermark lists two varieties for this species. Variety canadense has 30-60 achenes per head, achenes 2.5-3mm long. Upper surface of the cauline leaves mostly glabrous to very sparsely hairy.
Variety camporum has 60-150 achenes per flower head, achenes are 3-5mm long at maturity. Upper surface of cauline leaves with many appressed hairs. This latter variety is more common.

Photographs taken at the Kansas City Zoo, 6-17-99 and 7-10-00, and in the Ozark Scenic Riverways, Shannon County, MO., 6-15-03.
