I have had Crinum, x powelli presumably, clumps in largish pots for many years. 10" round or 12" square, normal depth, and they bloom every year with minimal feeding. The central bulb(s) which are more exposed always seem to bloom first, the side offsets which are large enough, bloom a couple of weeks later. Mine are stored in a frost free greenhouse over winter, but will survive in gardens with minimal protection from a wall etc. Mine are inevitably less vigorous than those in a local garden and less impressive when out of flower, which is most of the year of course. I have 2 - 4 flower stems in each pot normally. The first stem is just going over now.
