Bougainvilleas for frost free places.
Bougainvilleas have a long flowering season, splashing their colour throughout the warmer months. They are relatively pest free and are fast growing, and also relatively pest free. Being fast growing, the cane-like growth needs occasional pruning to keep the growth in check. The colourful "flowers" are actually BRACTS, which are a modified leaf. The real flowers are in the middle of the bracts. Plant them in a sunny spot for best results. Here are some photos of Bougainvilleas flowering in Sydney right now.

In this blog you captured Nature in a very beautiful way. Bougainvilleas is a very fast growing flower. And one have no need to do extra hassle to look after.

My question is that are bougainvillea like roots bound ? and my secong question is that are bougainvallea produce more flowers in roots bound conditions?
Answer to both questions is no. Roots will prefer open soil and plenty of space. The smaller varieties with double flowers are good for pots, but the bigger ones better in the garden.
Thank you very much for your reply and useful information!
