What is an azalea?

The azalea is a member of the rhododendron family of plants. It can be grown both indoors and outdoors. You can identify an azalea by its elegant, vibrantly-coloured flowers. The azalea japonica brightens up any garden. This garden azalea is a hardy shrub that blooms in spring.

The indoor azalea matches any interior, whether you’ve got a large or small space, a sleek or modern style. We offer a sheer unlimited range of pot sizes and shapes. Just don’t put this plant outdoors, because frost is not its best friend. With one exception: meet Azajoy®. This latest Hortinno variety first flowers intensely indoors, after which it can live for years outside in the garden.

    Characteristics of the azalea

    • Indoor azaleas add a splash of colour to any interior. They are available in a variety of pot sizes and shapes. Garden azaleas or the azalea japonica varieties are shrubs that make for a beautiful addition to any garden.
    • Indoor azaleas are non-hardy and therefore cannot withstand frost. The new Azajoy®, however, is an indoor azalea that is frost-resistant and can be moved outdoors after it has flowered indoors.
    • The indoor azalea is an air-purifying plant. The Hortinno Christine does a particularly good job of purifying the air, making it a healthy addition to your office or interior.
    • Both indoor and garden azaleas are available in a range of colours. Shades vary from creamy white to pink and from intense purple to deep red. Even combinations of colours are possible.
    • The azalea is easy to care for. With the right care, it will easily keep looking its best.
    • Indoor azaleas naturally bloom in spring, but in shops they are available from autumn through to May. The azalea japonica always blooms in spring; its prime months are April and May.
    • Azalea leaves are green with a characteristic oval shape. Beautifully dark green, glossy leaves are what sets the Hortinno azalea apart.

    What makes a Hortinno azalea so exceptional?

    • - Extra-long flowering time: 10 to 12 weeks, or flowers for 50 days!
    • - Clean and pure plants that shed few withered bracts
    • - With their dark green leaves, they are super air-purifying; the Christine and Classic azaleas score particularly highly
