Agapanthus, commonly known as lily of the Nile or Nile Lily, is a native of South Africa that produces large globe shaped flower-heads known as umbels on long slim architectural stalks. The blooms range in hue from white to lavender-blue to deep purple-blue and appear from late Spring through early Fall depending upon the cultivar. Agapanthus is a low maintenance plant and does not require maintenance pruning. Spent flower stalks should be removed and diseased or damaged foliage can be cut off. They are self sufficient and will thrive without pruning.
Remove any dead or diseased leaf straps by cutting them with secateurs at the base of the plant.
Remove spent flower stalks at their base by cutting them cleanly with secateurs after they have faded or just as they fade to encourage new blooming stalks.
Cut Agapanthus flower stalks for interior floral displays in vases filled with cool water. If keep out of direct sunlight indoors the blooms will last several days up to a week.
