That one does I hear. I think all citrus get citrus blooms on them. Now, the size of the blooms --- I don't know if they're the same or not. I have not seen Flying Dragon in person. I never would actually want one. Same reason I never wanted any Bougainvillea which grew so prolifically where our house is down south --- the thorns! --- I'm not fond of thorns. The Bougainvillea grow so fast & you have to keep up on pruning them (stuck by thorns) & then do something with the prunings (stuck by thorns) & any you drop during your doings & they'll go right through flip flops, tennis shoes, doggies paws. No thanks.
But yes, the Flying Dragon has some really, really wicked thorns --- rather THE feature of it.
