|discussion=<p>In California, <i>Viola sempervirens</i> occurs in shaded redwood forests and other coastal forest habitats. In Oregon and Washington, it occurs in Douglas fir and other coniferous forests, where it can form mats (clones) one meter or more in diameter; its prostrate, spreading growth habit is similar to <i>V. walteri</i>. The leafy stems of <i>V. sempervirens</i> are similar to the leafy stolons of <i>V. odorata</i>.</p>
