Symbolism & Meaning
In flower symbolism, azaleas represent deep affection, feminine beauty, and devotion. They are often given to express care and consideration, making them popular gifts for loved ones and family. In China, azaleas are associated with home and nostalgia, while in Victorian flower language, they carried a message of restrained passion or self-restraint.

Types of Azaleas
Azaleas are generally divided into two main types:
- Evergreen Azaleas (Japanese) – Smaller, compact shrubs with small, glossy leaves. Ideal for pots and small gardens.
- Deciduous Azaleas (Western or American types) – Taller, more fragrant, and with dramatic blooms in vivid colours.
Popular varieties include:
- ‘Kirin’ – Compact with soft pink blooms.
- ‘Northern Hi-Lights’ – Fragrant and cold-hardy with creamy-white flowers and yellow centres.
- ‘Gibraltar’ – A fiery orange-red deciduous azalea.
Frequently Asked Questions About Azaleas
Most azaleas bloom in spring, usually between April and May. Some indoor varieties (especially Indian azaleas) can flower in autumn or winter, depending on care and variety.
Prune azaleas right after flowering, ideally in late spring. This gives them time to set buds for next year. Cut back only lightly to shape the plant – avoid heavy pruning, especially in older plants.
Yes, all parts of the azalea plant are toxic to cats. Ingesting even small amounts can lead to drooling, vomiting, weakness, or more serious symptoms. Keep azaleas out of reach of pets.
After flowering, place your azalea in a cool, bright spot and keep the soil slightly moist, not soggy. Use acidic fertiliser for rhododendrons or azaleas from spring to summer. Avoid warm, dry air. For indoor azaleas, a cool rest period helps trigger the next bloom cycle.
Yes – but only from late spring to early autumn, once there’s no risk of frost. Choose a shaded or semi-shaded spot, and bring it back inside when temperatures drop below 10 °C.
Azaleas are part of the rhododendron family, but usually have smaller leaves, finer branches, and more delicate flowers. Most azaleas bloom on smaller, bushy shrubs, and some drop their leaves in winter, unlike evergreen rhododendrons.
That depends on the type:
Outdoor (Japanese) azaleas are usually evergreen.
Indoor (Indian) azaleas can be semi-evergreen or deciduous depending on the environment.
