Sedum lanceolatum
Sedum oregonense
Rock outcrops, rocky slopes, lava fields. Flowering May–Sep. 500–2500 m. Casc, Col, Sisk. CA. Native.
Sedum oregonense has loose, spreading rosettes with visible internodes. Its flowers are white or cream-colored but may appear yellow due to the yellow anthers visible within. The stout stem leaves are round to oblong, differing in shape from the oblanceolate rosette leaves. No similar Sedum grow in the Cascades, but confusion may arise in southwestern Oregon. Sedum oblanceolatum has narrower leaves, denser rosettes, and a mealy waxiness that rubs off onto ones hands. Sedum laxum has dense rosettes and normally has pink flowers.
