The photo above shows the developing floral stem or scape of Leiberg's stonecrop. Although some of the leaves appear opposite, most are alternate, so this is not Sedum debile. Photographed at the crest of the Columbia Hills in the eastern Columbia River Gorge..........May 1, 2005.

Characteristics:

Leiberg's stonecrop is a biennial or perennial wildflower with leafy, simple to sometimes branching stems from 5-12 cm high. The lower leaves are narrowly spatulate (See photos.), measuring 6-12 mm long. They are widest at the tips and taper gradually to the petioles. The upper leaves are alternate, shorter in length, and are broadly lanceolate or oblong in shape and measure up to 6 mm long.

The inflorescence is a spreading to recurved-branched cyme of numerous flowers. The 5 sepals are narrowly triangular to ovate-lanceolate in shape and up to 2 mm long. The yellow to greenish-yellow petals are narrowly lanceolate in shape and 5-8 mm long. The stamens are slightly shorter than the petals with the oblong-oval anthers up to 1.2 mm long.


Habitat:

Leiberg's stonecrop may be found on mossy, rocky banks and gravelly slopes, especially in canyons.


Range:

Leiberg's stonecrop may be found from Yakima County in Washington south to north-central Oregon and east to southeastern Washington and western Idaho, including the Snake River canyon.
