Silver-haired ivesia
Family: Rosaceae · Type: perennial · Native
Conservation status: CNPS 1B.2
Silver-haired ivesia is a rare (CNPS 1B.2) California native perennial found in the San Bernardino Mountains in pebble plains at elevations of 1,450 to 2,300 meters. Flowering from April to July, this plant produces white flowers approximately 10 millimeters wide in small, loose clusters. Growing with decumbent stems 10 to 20 centimeters long, it forms dense, silvery-hairy rosettes with a simple caudex. Its finely divided leaves feature 25 to 35 leaflets on each side, with tiny lobes 2 to 3 millimeters long that are elliptic to obovate in shape. The plant's distinctive silvery-hairy appearance and tightly clustered white flowers make it a delicate and eye-catching addition to its high-elevation habitat.
