Vegetative characteristics

Vancouveria chrysantha is a perennial herbaceous plant . A relatively short, mostly underground rhizome is formed.

The leaves are arranged in a rosette and are divided into a petiole and a leaf blade. The leaf blade consists of round, flat-lobed leaflets.

Generative characteristics

The flowering time in North America extends in spring from May to June. On a long, upright inflorescence stem with hairy, shiny branches, the pendulous flowers are arranged in a racemose inflorescence .

The hermaphroditic flowers are radial symmetry . The six inner sepals appear like petals . The light yellow sepals up to 1 centimeter long and bent back or up and stand out from the center of the flower. The actual, smaller petals, which are light yellow, curved and hat-like, are attached to the sepals. There are six stamens . The relatively large ovary is shiny.

The fruits ripen in North America from spring to summer in June to July.

The number of chromosomes is 2 n = 12.

Occurrence

Vancouveria chrysantha occurs in the western United States from northwestern California and to southwestern Oregon . It thrives in open evergreen mixed forests and in thickets on soils that form over serpentine rock at altitudes of 100 to 1500 meters.
