If you’re new to gardening, or would like to learn how to plant Zantedeschia, you’ve come to the right place! This handy guide includes everything you need to know about these striking summer blooms.
Zantedeschia, often known as Calla lilies, are popular exotic looking plants that are native to South Africa. Calla lilies are a florists dream, and will produce the most beautiful, colourful blooms throughout the season.
There are many distinctions between the different varieties of Zantedeschia. The most noteworthy is that they are either considered as ‘hardy’ or ‘tender’. In theory, with our climate in the UK, all varieties would survive a mild-normal winter as even the ‘tender’ varieties are hardy to -12 degrees celsius.
If you are worried about frost or live in a very exposed location, you can always add some winter protection like mulch or lift the tubers and store them through winter in a dry, cool and dark environment. They can then be replanted in spring.
The more tender Zantedeschia can be grown as a conservatory or house plant, as well as a patio plant. These tubers should be protected from frost with a deep winter mulch.

How to Plant Zantedeschia
Learning how to plant Zantedeschia is as easy as pie! They like moist, well-drained soil and prefer to be planted closer to the surface. Where possible, plant them in a sunnier location. As a native to Africa, they will appreciate it!
Plant the tubers shallow, so the top of the tubers are slightly exposed. Water freely and apply a balanced fertiliser every two weeks until the flowers have faded. Keep slightly moist in winter.
One of the many bonuses of Zantadeschia is their wow factor as cut flowers! Each tuber will produce several stems, perfect for cutting. Brighten up any room with a delightful bouquet or surprise your friends and family with a bunch of these stunning flowers.
Getting the most from your tubers
Calla Lilys can be lifted after flowering and stored throughout winter, allowing you to plant them again in spring. Simply dig them up once they have died back. The best time for this is usually in autumn, around the time the first frosts are beginning to set in.
Dust off the soil and place them somewhere cool and dry on some old newspaper for several days to allow them to dry off. They can then be stored in a dark, dry area and a cool spot in some peat moss over the winter.
Once spring arrives again and the temperatures turn mild, you can replant your Calla Lilys for a gorgeous show throughout the season!
