In summer, the small, richly colored blooms of blackberry lilies (Belamcanda chinensis) appear on wiry stems in shades of deep yellow-orange and red. Later, each 2-inch bloom produces a beige, pear-shaped capsule that, when split open, reveals glossy, black seeds resembling blackberries. Contrary to its common name, the blackberry lily is in the iris family and has swordlike foliage similar to tall bearded irises.
