I think I've probably seen more artificial Strelitzia reginae flowers than real ones, in my life. At least if we're talking about real flowers that are still attached to the plant. (They're not extremely common cut flowers in Iowa, but one sees them occasionally -- the flower shop in the garden center where I used to work had them fairly often.) In the garden center where I worked, on the few occasions when we got Strelitzia reginaes in, the suppliers had usually (always?) stuck a fake flower into the pot. They were surprisingly good fakes, too: I was fooled on two different occasions that I remember.
I wasn't tempted to buy this particular plant (it had scale, alas, plus I have so many BOPs -- mostly the white-flowering S. nicolai -- already that it actually seems excessive to me1), but the flower was still noteworthy. How long before I get a flower of my own, on the BOPs here in the house? Years, probably. Maybe never. It's not really something that happens indoors and in containers, not often. Do I care? Not especially. They're still cool houseplants.
1 Technically, I only have five: three S. nicolai, one S. reginae, and one that I haven't decided what it is yet but really really hope is S. reginae because nobody needs four S. nicolais.
