BOTANICAL AND ECOLOGICAL CHARACTERISTICS

SPECIES: Rosa gymnocarpa | Baldhip Rose
GENERAL BOTANICAL CHARACTERISTICS : Baldhip rose is a native, long-lived, deciduous shrub generally 3 feet (1 m) or less in height; however, heights of 3 to 9 feet (1-3 m) have been reported [11]. The stems are slender with straight prickles. The compound leaves have five to seven leaflets that are 0.5 to 1 inch (1-2.5 cm) long and 0.25 to 0.5 inch (0.6-1.2 cm) wide [4,7,9]. Baldhip rose is rhizomatous and has a shallow root structure [25,26,29,37]. RAUNKIAER LIFE FORM : Phanerophyte Chamaephyte Geophyte REGENERATION PROCESSES : Sexual reproduction: Baldhip rose attains sexual maturity at 3 to 5 years [18]. The seeds are eaten and dispersed by birds and mammals [13,14]. Information on seed viability and germination is lacking. Vegetative reproduction: Baldhip rose sprouts from the root crown and rhizomes [17,25,26,29,36]. SITE CHARACTERISTICS : Baldhip rose occurs predominantly in the low-shrub layer of moist, shaded forests of British Columbia and the Pacific Northwest. It is generally found at elevations of 5,000 feet (1,500 m) or less. It is well adapted to mesic-coniferous understories and grows best on eastern and southern exposures [20,27,31]. It is found in both mountainous and riparian areas [5]. Baldhip rose is adapted to a variety of moisture conditions but fares better on slightly dry sites [22]. It is adapted to a short growing season. Baldhip rose is found on coarse-textured, well-drained soils such as sandy loams, loamy sands, and cobbly loams [1,3,15,22]. SUCCESSIONAL STATUS : Facultative Seral Species Baldhip rose is shade tolerant; it persists from the initial plant community to climax. It flourishes initially with thinning and opening of the canopy, but then slows in growth [12,19]. Baldhip rose grows in full sunlight but has a higher overall survival rate in the shade [31]. SEASONAL DEVELOPMENT : Baldhip rose flowers in the late spring and early summer [4]. Hips appear at the end of July and remain on the plant throughout the winter [11,24].
