About Silverleaf Cotoneaster
An evergreen, upright to spreading shrub with slender arching branches and small elliptic leaves, green above and persistently white-woolly beneath. Compact clusters carry small flowers with spreading white petals and dark pink-purple anthers. Red small apple-like fruits retain an open calyx and usually contain two hard pyrenes. Established wild occurrence warrants observations of occupied cover, reproductive plants and new recruits. These measurements can test persistence and spread. The reviewed accounts do not quantify an island-wide effect on Kauaʻi native vegetation.
