Summer snapdragon is a tender perennial that produces tall spikes of small snapdragon-like flowers in shades of purple, pink, white, and bicolors throughout the warm season. It thrives in full sun and performs well in containers or garden beds with regular watering.

Why grow it

Summer snapdragon offers continuous flowering through warm months in a form more compact and heat-tolerant than true snapdragons (Antirrhinum majus), making it useful for gardeners in regions where traditional snapdragons struggle in midsummer. It performs reliably in containers and is less prone to rust and powdery mildew than its snapdragon relatives, though it requires consistent moisture and heat to thrive.

Watch out for

Plants may become leggy or decline in vigor as temperatures cool in fall, even in mild climates where they technically overwinter. Inconsistent watering can lead to stress and reduced flowering, so consistent moisture management is more demanding than in drought-tolerant alternatives.
