Tip #8: Agapanthus (Lily of the Nile)
Agapanthus produces magnificent globe-shaped clusters of deep blue or white flowers resting atop strong, elegant stalks. Whether cultivated indoors in bright sunrooms or outdoors on sunny patios, agapanthus is famous for needing tight root binding before setting flowers. When you plant young agapanthus divisions in large individual pots, you might wait three to five years without seeing a single bloom because the plant devotes all its energy to root expansion.
To achieve reliable summer flower displays, nestle two or three agapanthus plants tightly together inside a 10-inch or 12-inch container. The thick, fleshy roots will quickly bind together, generating beneficial root pressure that drives growth energy upward into tall flower stems. Leave your agapanthus in the same container until the muscular roots physically distort the pot walls. Recognizing when not to repot this sun-loving plant saves physical effort while guaranteeing a striking floral display every summer.
