OK, there are issues with them, depending where you are located in the world.
For instance, I never really had good results with them in the UK.
Considered too blousy or gawdy by the purests but don’t let that put you off.
If you live in an area where Bougainvillea grow easily they are ideal for Bonsai beginners and the experienced Bonsai grower alike.
- Bougainvillea should flower profusely
- Bougainvillea are relatively easy to prune and shape
- Bougainvillea do not suffer too much with pest and disease problems
- Bougainvillea bracts come in a number of colours
- Bougainvillea can be grafted
Here are some pictures taken from a Bougainvillea Bonsai show in Shenzhen China.
They grow very well here in the South of China.
Some of these specimens are 5/6 feet high. It might be argued that this is not Bonsai but maybe Topiary.
The counter argument could be – It is a miniaturised (tallest Bougainvillea now believed to be in China and currently reaching 100 feet tall and still growing) tree in a container and as such qualifies as Bonsai.
