Zantedeschia–a colorful name for a complicated flower. These lovely, long-legged blooms are commonly referred to as "Calla Lilies," and even though they are not true members of the Liliaceae family, we let them get away with it because they're so darn pretty.
LIGHT
Light, of course, is essential for all plant cultivation, but most importantly, it's the type of light that really matters. And what Zantedeschia want is diffused light. Diffused light simply means that the light is scattered, as opposed to direct. There are several ways to achieve this, which we will discuss later. Zantedeschia also want UV light. You know that lower range of the light spectrum that gives you a killer tan or a wicked sunburn? Well, it also has an effect on the growth of Zantedeschia. The kind of light as well as its intensity has a huge influence on the color saturation and clarity of the blooms as well as the length of the plant.
