| Okanoganense is a prostate, mat or cushion-forming semi-evergreen perennial with succulent stems and gray-green leaves. Produces single, short-stemmed, saucer-shaped white flowers, tinged pink or yellow with yellow stamens. In general, this group of plants is made up of annuals, biennials, and perennials. Leaves are often succulent and deciduous, but may be semi-evergreen. Flowers are showy and saucer-shaped, borne in cymes or panicles. These relatively short-lived plants require well-drained soil that has either poor or moderate fertility, and full sun. |
