INCA Treasure

Trouble-free Inca lilies offer an abundance of colourful blooms from late spring to mid-autumn

Members of the Amaryllidaceae family, alstroemerias or Inca lilies are tuberous-rooted perennials originating from South America. They do very well in most parts of South Africa, particularly in areas with good summer rains and cool temperatures. Long-lived, they make a fabulous addition to borders, adding colour throughout summer. They are available in a wide range of colours, including red, orange, pink, rose, salmon, purple, yellow and white, with many sporting contrasting whiskers and rouged cheeks.

They also make excellent cut flowers lasting up to three weeks in the vase and, as a result, breeders have been releasing new varieties on a regular basis.

POSITION

While Inca lilies love a sunny position, in hotter regions they’ll appreciate a bit of midday or afternoon shade. As they prefer well-draining soil, dig in plenty of compost when preparing the bed. High soil temperatures can inhibit flower production so add a thick layer of mulch around those newly planted. Taller varieties can form large clumps so give them enough space to spread out.
