Peter Pan Lily-of-the-Nile. This is a dwarf form with medium blue flowers and only 12" tall. As with all other Agapanthus, plant in full sun and lime annually to get consistent flowers. I often hear the claim that my Agapanthus flowered well the first year or so after. So my first question is always, "When did you last lime your plants?" One needs only to fertilize sparingly.
