I have been growing Agapanthus campanulatus ssp campanulatus from Silverhill seed outside since 2006, during which it has experienced a minimum temperature of -2o F. It is in a fairly protected position to the south of the house; I do not mulch it heavily. It blooms (in July) and increases well, in fact I just dug up 5 divisions. It has also set viable seed. Yes, it has marvelous curiosity value, but above all it is an excellent garden plant.
I grow this plant in pots indoors from Oct.-April then put the pots outdoors during the summer (zone 5). They bloom indoors sometime between March and April, but never bloom outdoors. My plants are severely rootbound and probably getting too large for their pots. I plan to divide them when they are finished blooming, but I am unsure of the ratio of plant to pot size. I would like to hear other's experience with growing this plant in pots.
