snoodle - all my agapanthus are in pots that i bring into an unheated GH for the winter. As woody says, i think it is keeping them dry that is more important than the cold. We have clay soil. My Dad has sandy soil and they grow in his garden, without protection, like (very pretty) weeds.
Woody - enjoy Hampton Court next week - we are going on the Weds - fingers crossed for no rain !!
