Virginia marsh St. John's-wort

Hypericum virginicum is a small herbaceous plant growing up to 70 cm (28 in) in height. Its leaves are sessile and opposite, sometimes clasping. The flowers grow up to 15 mm (0.6 in) in diameter, with 5 pink or white petals. It flowers in the summer to early fall and grows in bogs, wet meadows, fens, swamps, and along lakeshores. It can be distinguished from the closely related Hypericum fraseri by its longer, acute sepals, and longer styles. The seeds of H. virginicum closely resemble those of the extinct paleospecies Hypericum tertiaerum.
