History
Angelonia angustifolia, commonly called summer snapdragon or angelonia, is a tropical herbaceous perennial native to Mexico, the Caribbean, and northern South America. American botanist George Bentham described it in 1839. The plant produces erect spikes of small orchid-like two-lipped flowers in violet, purple, pink, rose, or white atop narrow aromatic foliage.
Despite being a minor tropical bedding subject for decades, breakthrough breeding by Ball Seed introduced the Serena F1 series in 2001, followed by Proven Winners' Angelface, Ball's Archangel, and Selecta's Serenita. These hybrids made summer snapdragon one of the top-ranked heat and humidity tolerant annuals for US gardens, especially in the Southeast and Gulf Coast where few other vertical flowers thrive in midsummer.
Flowers often emit a faint grape candy fragrance. Native to Mexico, Central America, and the Caribbean, introduced to American gardens in the 1990s. Ball Horticultural's AngelMist and Proven Winners' Angelface series dominated the 2000s, giving Southern American gardeners a snapdragon-like flower that thrives in brutal summer heat and humidity.
Symbolism & meaning
What It Symbolizes
Summer Snapdragon brings angelic grace to gardens where heat would make a true snapdragon collapse. Its slender spires of orchid-like blooms hold steady through humid Southern afternoons, an emblem of summer poise. Where cooler-season favorites fade, Angelonia carries the floral chorus through July and August with composed, unwilting elegance — the very image of southern summer grace.
- Summer angel — graceful in the worst heat
- Southern grace — thrives where snapdragons fail
Where the Name Comes From
The name Summer Snapdragon describes flowers that open like a dragon mouth. 'Angelonia' from Venezuelan common name 'angelon' used by local people for the plant; 'angustifolia' means narrow-leaved.
