I have one 'bird of paradise' (Strelitzia sp.). It was doing well during the summer but is struggling indoors. I see browning of leaves and has a general appearence of withering. ( I will post a photo soon).
They can be bought from many garden centres but are generally expensive ( at least here in Toronto, CA). I believe they start at around $70 and go all the way up to $250 each.
I am not sure of the colour of mine but I am hoping it is red-yellow-orange, which are really quite stunning to look at
