More Information About Zantedeschia
We are pleased to make available some of the lesser-known calla lily cultivars and newer hybrids, which make superb garden plants. Zantedeschia is an aroid whose attractive flowers are incredibly popular and symbolize divinity and purity, which is why calla lilies are so frequently used in weddings and funerals. White calla lilies are the most popular for cut flowers, but in the garden, bright colors are also popular including pink, yellow, orange, and purple calla lilies. Some people use the common name arum lily for Zantedeschia but we always call them calla lilies and reserve Arum lily for the genus Arum.
Zantedeschia aethiopica is the most commonly grown species, but most floricultural calla lilies are hybrids whose other parent Calla species bring in traits such as spotted leaves and an array of colorful flowers such as purple, red, pink, orange and yellow. We think you will really enjoy the calla lily selections we have chosen.
How to grow calla lily plants
- Winter Hardiness - Where calla lilies aren't winter hardy they are easy to dig in fall and store dry (in barely moist peat) through winter.
- Dormancy - Gardeners should be patient with their calla lilies. While the white-flowered Zantedeschia aethiopica is a winter grower and will start to grow as soon as the weather warms up which revs up the growth, all the other species of calla lilies are winter dormant and usually don't wake up from their winter dormancy until May or June.
- Water and Soil - In the wild, Z. aethiopica calla lilies grow in marshy conditions and thus can tolerate moist garden sites as long as winter drainage is good. Although Z. aethiopica thrives best in moist, rich sites, it is amazingly durable under less than ideal conditions. In general though, wetter is better and wetter = more flowers. All the other calla lily species and their hybrids, Z. albomaculata, Z. elliotiana, Z. rehmannii etc., are not bog plants and instead prefer a drier, more typical garden soil...well-drained but with consistent moisture. In the winter, bulbs of these calla species are more susceptible to winter rot if the soil is too wet.
- Bulb Depth - Also, Calla Lily bulbs prefer to be planted somewhat shallow...about 1 inch or so. They have contractile roots that will draw the calla bulb down to its preferred depth.
- Sun - Calla Lilies prefer full sun unless you are in the deep south and then partial sun will do.
