❓ How do you recognise this plant?

Sold by the million every autumn in France for All Saints' Day, the indoor azalea is in fact a shrub native to China and Taiwan, forced into flower out of season in greenhouses. Both are evergreen shrubs with colourful flowers in late winter/spring — camellia has much larger, glossy leaves and rose-shaped flowers, azalea has small, hairy leaves and clustered funnel-shaped flowers

🍃 Leaves

Evergreen, small, ovate, dark green, hairy on young shoots

🌸 Flowers

Numerous, funnel-shaped, single or double, white, pink, red or bicoloured, grouped in 2 to 6 at the end of the shoot

🍎 Fruits

Small dry brown capsule, barely visible

🪵 Bark

Thin, grey-brown, young shoots hairy

🗺️ Distribution

Native to south-eastern China and Taiwan; grown worldwide

🐝 Value for pollinators

Of little use indoors (out-of-season flowering); in the open ground, attracts bumblebees and butterflies in spring

✂️ Horticultural uses

One of the best-selling flowering pot plants in France, traditionally given on All Saints' Day to decorate graves; very many cultivars of flower colour and form

⚠️ Possible toxicity

All parts (leaves, flowers, nectar) are toxic if eaten, like most Rhododendron (grayanotoxins)
