Oregon stonecrop is an evergreen groundcover with attractive, year-round appeal. It's especially striking in summer when clusters of bright yellow flowers burst into bloom atop short, upright stems, beckoning neighborhood bees and butterflies. Depending on growing conditions like sunlight, heat and soil, its compact, succulent leaves can vary in color from green to red.

Gardening with Oregon Stonecrop: This is an excellent choice for partial to full sun rock and pollinator gardens with moist to dry, well-drained soil. It is relatively easy to grow, spreading laterally to colonize areas over time. If you hope to achieve this consistent groundcover effect, a good strategy is to buy enough so you can space them every foot or so.
