About Philippine Violet

An erect, branching perennial shrub with hairy stems and pointed elliptic to narrowly ovate leaves, dark green above and paler below. Violet, pink or white funnel flowers are accompanied by slender spiny bracts and two large outer calyx lobes with spiny margins. Smooth, glossy brown mature capsules remain enclosed by the enlarged calyx; flattened brown seeds have appressed wavy hairs. 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.
