Calla Lilies (although not considered true lilies) are a very popular flower especially as cut flower for wedding displays and bouquets. Also known as Zantedeschia or Arum Lilies. This stunning flower is available in a multitude of colours and is ideal for use in beds and borders. You can also grow calla lilies in containers either outdoors or in a sunny window position indoors. Calla lilies will bear narrow, lance or funnel shaped flowers and are particularly effective when grown in groups within a border, or planted in pots and spread out on the patio.
Planting calla lilies in the garden
Plant in the spring months for flowers in June/July. Calla lilies want bright but indirect sunlight, so find a suitable position in your garden with free draining soil. Depending on how you want your display to look, you can space your rhizomes 30cm (12″) apart or plant in groupings of 3 rhizomes slightly closer together.
Harts’ Hint
” Add a good multipurpose compost to garden soil to improve the texture. “
