There are four members of the stonecrop family in Rainier, three with brillant yellow flowers. All have short, thick and succulent stems. S. oreguanum rises only 4 – 8″ (10- 20 cm) above the ground. The leaves are spoon-shaped or nearly round, thick, fleshy and glossy appearing ready to pop. The highly attractive luminescent flowers have five narrow lance-shaped petals, usually less than a 1/2″ long. Uncommon in Rainier, found on rocky open sites below 5,500′ elevation.
