Key Identifying Features
Angelonia (Angelonia angustifolia), nicknamed summer snapdragon, is a heat-loving tender perennial grown as an annual. It is recognized by its upright flower spikes lined with small, orchid-like, two-lipped blooms.
- Upright, bushy habit, usually 12-24 in (30-60 cm) tall
- Flowers arranged in loose vertical spikes at the stem tips
- Each flower is small (~0.5 in), two-lipped, slightly cupped like a tiny orchid or snapdragon
- Colors: purple, blue-violet, pink, white, and bicolors
- Foliage often has a faint grape-like fragrance when crushed
Leaves & Stems
Leaves are narrow, lance-shaped to linear, 1-3 in long, with finely toothed (serrated) margins and a pointed tip. They are deep green and arranged oppositely along the lower stem, sometimes becoming alternate near the top. Stems are upright and slightly sticky-hairy, branching to form a tidy, well-clothed plant that holds up in heat and humidity.
Flowers & Fruit
Each flower has a distinctive two-lipped (bilabiate) shape with a small pouch or spur at the back and often a contrasting spotted throat — the orchid-like look that gives angelonia its charm. Flowers open from the bottom of the spike upward over a long season. The plant blooms continuously through summer heat without deadheading. Seed capsules are small and rarely significant in garden ID.
How to Tell It Apart from Look-Alikes
- True snapdragon (Antirrhinum): flowers are larger, tubular, and "snap" open when squeezed; angelonia flowers are smaller, flatter-faced, and do not snap. Snapdragons also prefer cool weather while angelonia thrives in heat.
- Salvia spikes: also upright, but salvia flowers are tubular with a hooded upper lip and the plant often has square stems and aromatic foliage.
- The small orchid-faced two-lipped flowers on slender summer spikes + narrow toothed leaves + grape scent confirm angelonia.
Where You'll Find It
Angelonia is a popular summer bedding and container plant for hot, sunny spots where it blooms reliably when many annuals fade. It tolerates heat, humidity, and some drought, and is widely used in borders, mass plantings, and cut-flower arrangements. It is propagated mostly from cuttings of named series.
Quick ID Checklist
- Upright bushy annual with vertical flower spikes
- Small two-lipped, orchid-like flowers with a spotted throat
- Narrow lance-shaped leaves with toothed edges
- Faint grape scent when foliage is crushed
- Thrives and blooms through summer heat
- No deadheading needed for continued bloom
Frequently asked questions
Why is angelonia called summer snapdragon?
Its upright spikes of two-lipped flowers resemble snapdragons, but unlike true snapdragons it thrives in summer heat and humidity, earning the nickname summer snapdragon.
How is angelonia different from a real snapdragon?
Angelonia flowers are smaller, flatter-faced, orchid-like, and do not 'snap' open when squeezed. It also loves heat, whereas true snapdragons (Antirrhinum) prefer cool weather and have larger tubular flowers that snap.
Does angelonia have a scent?
Many angelonias release a faint grape-like fragrance when the leaves are crushed, which can be a helpful secondary clue alongside the flower shape.
Do I need to deadhead angelonia?
No. It blooms continuously through the season without deadheading, flowering from the bottom of each spike upward, which is part of why it's valued as a low-maintenance summer plant.
