Calycanthus occidentalis (Californian Allspice) is a large, upright-rounded, bushy, deciduous shrub boasting fragrant, deep red flowers, 2 in. across (5 cm), adorned with many strap-shaped petals from late spring to early summer with sporadic blooms until early fall. Resembling waterlily blossoms, each flower lasts only 1 day, but they are produced in great quantities. The fragrance is often described as the aroma of a wine cellar or vinegar. The blossoms give way to capsule-like fruits which persist into winter. The lush and aromatic foliage of large, leathery, dark green, ovate leaves, 8 in. long (20 cm), turns an attractive golden-yellow in fall.
