The calla lilies are a beautiful genus of flowers that have been enjoyed by humans for centuries. The calla lily grows from a type of bulb called a rhizome and produces very large green leaves, typically covered with lighter-coloured spots. The flower blooms from the top of a rather thick stem and sort of resembles trumpet shaped rolled paper, having a texture ranging from rather fleshy to wet autumn leaves. A grouping of calla lilies is a wonderful addition to any garden, since they are relatively easy to grow and are an absolute favourite as a cut flower inside the house.
