Azaleas are very diverse, and with a wide range of colours, there is something for everyone. Here we present the most beautiful types of azaleas for the garden and home.
Want to keep an azalea in the house or garden, but cannot decide? The diversity of azalea species and varieties is enormous. To make the decision a little easier, we provide a small overview, dividing into hardy garden and frost-sensitive indoor azaleas.
Types of azaleas: the most beautiful garden azaleas
Garden azaleas come in different sizes and colours. Species such as Rhododendron molle and Rhododendron luteum lose their foliage in winter, while Rhododendron molle subsp. japonicum is evergreen, but also planted in the garden. In addition, there are again numerous varieties in different colours.
- Rhododendron molle: this is the classic garden azalea. It originates from China and Japan and is also the parent species of many azalea hybrids. The deciduous shrub, like all garden azaleas, is hardy.
- Rhododendron luteum: this yellow azalea is also called Pontic azalea or Azalea pontica. It is a typical garden azalea, which also impresses with a distinct, sweet floral fragrance. The actual species blooms yellow, however there are several hybrids with other azaleas that may have other colours.
- Rhododendron molle subsp. japonicum: the Japanese azalea, or dwarf azalea, remains rather small and compact. Unlike most other garden azaleas, it retains most of its foliage in winter and also displays pretty autumn colour.
- Rhododendron obtusum ‘Kermesina’: also offered as Japanese azalea ‘Kermesina’, it captivates with its bright blooms that appear only briefly between late May and early June. The flower colour of this variety can be bright red or rich pink.
- Knap Hill azalea: large-flowered Knap Hill hybrids are also fragrant and can bloom in colours ranging from white to pink and red to orange and yellow. It has not been conclusively clarified who exactly the parent species of these hybrids are. Here, too, there are many different varieties.
- Rhododendron obtusum ‘Bloom Champion’: the special thing about azaleas is the extraordinarily long flowering period. The first flowers appear in April, the last flowers disappear when frost sets in. It is wintergreen and comes in different colours of flowers.
Tip: It is also possible to cultivate the Japanese azalea as a bonsai. However, it must then stand outside as it does not particularly appreciate the warm climate indoors.
The best indoor azaleas
Indoor azaleas usually include the varieties of Indian azalea (Rhododendron simsii). Almost all indoor azaleas go back to this species. There are varieties in white, pink and red, double or single and even bicolour flowers. For simplicity, we have sorted the different varieties by colour.
- Pink azaleas: indoor azaleas with pink flowers include the varieties ‘Aquarell’, whose flower colour is so light pink that it almost appears white, ‘Christine Matton’, which has salmon-coloured flowers, or ‘Dame Melanie’, whose flowers appear light pink and are speckled.
- White azaleas: the ‘Angelina’ variety captivates with double, white flowers, while ‘Sachsenstern’ also blooms white, but produces only single flowers without filling.
- Red azaleas: ‘Alexander’ is a red-flowered indoor azalea, which blooms from January to May. The flowers are not double, but single.
- Pink azaleas: the varieties ‘Inga’ and ‘De Waele’s Favorite’ have simple flowers that shine in pink and have a white edge. The variety ‘Friedhelm Scherrer Roze’ also produces pink flowers, but the colour intensity can vary greatly from specimen to specimen.
- Orange azaleas: ‘Rosalea’ is an indoor azalea with orange flowers, which shows its flowers in the cold season.
Tip: Satsuki azaleas are especially suitable as azalea bonsai. They are a group of varieties from the Rhododendron indicum species and are mainly cultivated in Japan.
