Allamanda cathartica

& other Allamanda species, hybrids and cultivars
Apocynaceae

Allamandas are old favourites for subtropical gardens and worth a fresh look given the renewed need for tough plants that can withstand drought.

The most familiar are the yellow climbing (or scambling) types. Semi-shrubs and shrubs are also available, while new cultivars have expanded the colour range. One of the traditional yellow forms would certainly be appropriate for someone trying to recreate a traditional Queensland garden. Any colour would be an asset to a tropical garden.

Other species include:
A. schotii (=A. nerifolia)
A. violaceae (= A. blanchetii, A. purpurea)

Some of the cultivars currently available on the market may be hybrids.

Be aware that some Allamanda has weed potential in vulnerable areas (see links below). If you're unsure, check with relevant local authorities.


Where to buy Allamanda

Most general garden centres in sub/tropical parts of Qld will probably have some Allamanda for sale, although you may have to hunt around for some varieties.

If you operate a nursery offering many types of Allamanda for sale in Qld, or stock rare or unusual types, please get in touch. Information for potential advertisers
