Our bougainvillea, sitting in a pot on our front terrace area, doesn't seem to be very successful for much of the year. In May, when bougainvilleas typically flower profusely, it was rather sparse.
But for some reason, ours is doing rather well in September this year:
It's predominantly pink; not my favourite colour in general, but I do like the deep pink of some flowers (or, technically, bracts in this case. The flowers are the tiny, insignificant white ones in the middle of some of the bracts). The very pale, almost white bracts interspersed with the pink makes it very attractive.
