Pretty Carroll Lavender Cotton
Santolina chamaecyparissus 'Pretty Carroll' is a compact, evergreen shrub known for its aromatic, finely textured silver-gray foliage that resembles the scales of a cypress tree. In mid to late summer, this cultivar produces small, bright yellow flowers that are borne in clusters, offering a cheerful contrast to its silvery leaves. The plant's dense, mounded habit makes it a great addition to borders or rock gardens.

Design tip
Plant ‘Pretty Carroll’ into gaps between larger rocks or along the edge of gravel paths, where its compact silver mounds can soften the surrounding stone. The bright yellow summer flowers add small bursts of color without overwhelming the restrained, drought-tolerant planting.

This plant can be seen at the Bellevue Botanical Garden.
