We have one LARGE bulb of B. josephinae planted out at RBG which flowers every year (I think this happens in Aug./Sept., if i remember correctly), but it took about 12 or 15 years to reach blooming size. I would estimate the diameter of the inflorescence to be about 2 1/2 feet, with the flowers rather widely spaced but very attractive. We are growing seedlings of it, but since we have only the one flowering-size bulb (there are 2 smaller ones which have yet to flower), then the seedlings must either be a)the result of self-pollination, or b)the result of pollination by Amaryllis belladonna, since there is a white-flowered clump of this not far away which flowers at the same time.
