Large Agapanthus (Southsea PO4)

Large Agapanthus (lily of the Nile). Stunning large blue flowers in summer. Healthy and hardy perennial which needs very little care and copes with dry, heat or cold. It gets bigger every year, probably about 15 to 20 plants now. It would need digging up which I can't do. Probably not in the heat wave! I would like to keep a couple of the plants. Free.
