SPIRAEA. Widespread, Northern Hemisphere. Deciduous shrubs of the rose family, often quite graceful and delicate in texture. They have slender stems, oval toothed leaves and dense, often head-like clusters of tiny flowers. Sun or light shade, reasonably well drained soil, moderate watering. Hardy to below 0^oF.

densiflora 'Trinity Rose'. Selected by Suzanne Schettler in the Trinity Mountains of California, this is a compact 2½' shrub with attractive bluish green leaves, crowned by 2" clusters of rose pink blossoms in early summer.

douglasii. This is another California and northwestern native, though considerably more robust than the last. It makes broad thickets, standing as much as 6' tall. The leaves are pale green to bluish green, with furry greyish undersides. It blooms in summer. The tall, branched flower clusters are tinted various shades of pink. The current, unnamed selection has particularly large flower clusters, rose pink in color.
