Snapdragons (Antirrhinum) are popular annual or short-lived perennial flowering plants known for their unique flower shape, resembling a dragon's snout that can be "snapped" open and closed. 1 They come in a wide array of vibrant colors, including pink, red, yellow, orange, white, and bi-colors. 2 The flowers grow in tall, elegant spikes that bloom from spring through fall, often with multiple flushes. 3 Their lance-shaped leaves are typically dark green. 4 Snapdragons range in height from dwarf varieties (under a foot) to tall cultivars (up to 3 feet or more), making them versatile for borders, beds, containers, and cut flower arrangements. 2 They prefer full sun and well-drained soil. 5
