A strong colour on a small plant
Red azaleas run from scarlet through crimson to a coral red, and many have a slightly glossy sheen on the petals. In the language of flowers azalea has traditionally suggested fragile passion, and red adds to that mood. Used as a pot plant, it makes a focal point in a room or on a shaded veranda.
What spoils the display
Red petals fade quickly in direct sun, and a crisp edge to a flower can mean the plant is too dry or too hot. Most florist azaleas hold their blooms best between about 12 and 18 degrees Celsius, which is hard to give in an Australian summer or in a heated home.
- Move the plant to the coolest bright spot you have.
- Water before the mix is completely dry, never after the leaves have wilted.
- Remove spent flowers so energy goes to new buds.
- Spray the leaves gently with water on hot, dry days, and keep the flowers dry.
Looking ahead
When flowering is over, trim lightly and move the pot outside to a sheltered spot with morning sun. Plants usually set buds for next season in late summer and autumn, so keep watering through the warm months. Red azaleas grow best in mild regions such as Melbourne, Sydney, Hobart and the hills near Adelaide; in tropical Cairns and Darwin they struggle.
Grayanotoxin warning
The ASPCA rates azalea as toxic for dogs, cats and horses because of grayanotoxins, with drooling, vomiting and weakness the main signs. Keep pots out of reach and call a vet at once if you suspect a pet has eaten leaves.
