Begonia Blooming

I went into work one day to find this plant on my desk.
A kind gift from a colleague for whom I had done a favour.
6 months on, it has bloomed all summer long and now in mid November it still has dozens of flowers, which to be honest are brightening up our conservatory nicely despite very little help from me
A few flowers wilt daily but seem to be replaced by at least 6 more!
Needless to say we are very impressed with a Sainsbury's plant!
