Flowers urn-shaped, white or pinkish, borne in spring in broad, short, rather pendulous panicles.

Native of S. California. A handsome species, but tender.
A. pringlei Parry var. drupacea Parry A. drupacea (Parry) McBride – It should have been added that the species itself was described from Arizona and does not occur in California. The var. drupacea, said to differ mainly in its nutlets tending to cohere into a single stone, is a native of southern California and of the Mexican state of Baja California.
The distinguishing characters of A. glauca and its allies are that they are tall shrubs with leaves that are grey-green on both surfaces and have inflorescences in which the pedicels are longer than the bracts. Apart from A. pringlei, two other species in this group are in cultivation – A. mariposa Dudley and A. viscida Parry.
