Growing Agapanthus africanus – Blue African Lily

In areas that receive very light frost, plant bulbs deeper in the soil and cover well with mulch in the fall. agapanthusIn areas prone to more severe frost, grow in pots and winter indoors in a frost-protected area such as a shed.

Blue agapanthus reaches a height of 3 to 4 feet tall and grows in clumps. It makes for an especially breath-taking addition to a garden as a background plant. If growing in a small area, choose semi-dwarf variations such as blue 'Peter Pan' agapanthus.
