Calla lilies are at their most glorious in full sun, which means six hours of sunlight a day. According to the University of Minnesota Extension, while calla lilies can grow in part shade – and if you live in a hot climate, shade is absolutely necessary – their blooms won’t be as impressive.
Calla lilies prefer full sun or part shade, though their blooms will be less impressive in shaded conditions. In areas where summers are long and hot, calla lilies often do better in partially shaded environments where they can get a break from afternoon sun. In cooler environments, they tolerate full sunlight well.
Do calla lilies get sunburns?
Calla lilies can suffer from sunburn if they are exposed to too much harsh afternoon sun. This can happen in hot dry climates where the sun is hot and the soils are drier. In this case it is best to plant calla lilies in a position that gets protection from afternoon sun.
What zone do calla lilies grow in?
These flowering plants are hardy in U. S. Department of Agriculture zones 8 to 10. Calla lilies can be grown as perennials in frost-free climates or overwintered indoors in colder regions. Calla lilies grow best in full sun, but they need shade during the summer in hot climates. True lilies have six petals.
Calla Lily as a Houseplant First of all, calla lilies actually prefer to grow as a marginal aquatic plant and oftentimes is found growing on the edges of streams or ponds. This is a wonderful benefit for people that tend to water a lot! Keep your indoor calla lilies continually moist and never allow them to dry out.
When I was researching we ran into the inquiry “Can I leave calla lilies in the ground this winter?”.
Most calla lilies are winter hardy in zones 8-10, so in these warm climates the rhizomes can be left right in the ground. If you live in a colder area and you want to save your rhizomes for next spring, you may dig them up before the first frost and store them over winter before replanting them next spring.
