Persian Buttercup is a perennial from the eastern Mediterranean and Southwest Asia, grown in U.S. gardens and for bouquets. Most garden plants are cultivars or hybrids, often with rose-like layers of petals. Eating the plant can irritate the mouth and stomach, and its sap can irritate skin.

Common single Poppy Anemones have a few broad petals around a conspicuous dark center. Common double Persian Buttercups have many tightly layered petals and a rounder, rose-like bloom.
