Angelonia gardnerii: The Graceful Summer Snapdragon

The Heat-Loving Snapdragon Alternative

The Heat-Loving Snapdragon Alternative

Angelonia gardnerii, known as Angelonia or Summer Snapdragon, is a Brazilian native that provides snapdragon-like flowers through the hottest summer months when true snapdragons have faded. Its heat tolerance and continuous bloom make it a southern garden essential.

Botanical Classification

Family:	Scrophulariaceae (skrof-yoo-larr-ee-AY-see-ee)
Genus:	Angelonia (angel-on-ee-a)
Species:	gardnerii (gard-NAIR-ee-eye)

Spikes of Summer Color

This upright, bushy annual/perennial grows 12-18 inches tall and wide with narrow, lanceolate, slightly toothed leaves. The flowers are borne in dense, terminal spikes: snapdragon-like, 3/4 inch across, in shades of violet, purple, pink, and white, often with contrasting throats. Blooms continuously from late spring through fall without deadheading.

Angelonia thrives in full sun with well-draining soil. It's exceptionally heat, humidity, and drought tolerant—superior to snapdragons in southern summers. Water regularly for best bloom but it withstands dry spells. Hardy in zones 9-11 as a perennial; universally grown as a summer annual.

Reliable Summer Performance

Use in beds, borders, containers, and cutting gardens where continuous summer color is needed. The spikes add vertical accent. Combine with lantana, pentas, zinnias, and ornamental grasses for a heat-proof palette. No deadheading required—self-cleaning. A low-maintenance, high-reward plant for challenging summer conditions.
