Bishop of York peony dahlia (Dahlia 'Bishop of York') produces spikes of 3½-inch daisylike golden flowers blushed with orange above dark purple-tinted foliage throughout the growing season. These nonhardy perennials are most often available through local garden centers after danger of the last frost has passed. Plant in full sun in moist soils. This dahlia is not significantly troubled by pests or diseases in the Chicago region.

Dahlias were cultivated by the Aztecs well before the conquistadors arrived in central Mexico. Native to the high plains of Mexico through Central America, these plants are hummingbird magnets wherever they are grown. The Spanish introduced dahlias to Europe in 1784, and the curator of the introduction station in Spain named the genus in honor of Andreas Dahl, a student of Carl Linnaeus. This cultivar name is slightly inaccurate, as the diocese of York has an archbishop, not a bishop.
