My "Hillier's Foliolosa" with a yardstick (91 cm.) for scale. The cane towering above the yardstick is about 4.5 feet tall and the lax, arching canes even longer. Just like the tubular stipules, this is characteristic of Rosa palustris, not Nuttall's foliolosa which is hardly more than 1.5 feet tall. Photographed August 1, 2020 at "Rose Woods".
The red flowered rose that has passed for Rosa foliolosa for at least 130 years is a tall growing (over 6 feet) palustris type. The true foliolosa is less than 2 feet tall with flat stipules and white flowers. See the "Members Comments" for additional remarks. Photographed by Dorothy Tallman at Santa Barbara Botanic Garden June 30, 2014.
A colony of the white flowered Rosa foliolosa Nuttall growing in an arroyo adjacent to the administrative offices at Santa Barbara Botanic Garden. Note the handrail on the left for scale, plants are about 1 foot tall. This colony is several decades old. Photographed by Dorothy Tallman on August 26, 2014.
