Latin Name: Zantedeschia
Common Name: Calla Lily
The Calla Picasso has a large purple and cream flower with small spotted green foliage. Calla lilies are a wonderful addition to any garden and are popular for bridal bouquets and cut flower arrangements. They prefer moist soil, grow best in full sun in humus-rich soil. Outside of zones 8-10, dig up the rhizomes in late fall, remove the dirt without washing, dry for a few days, and place in a cool dry place until ready for planting the next spring.

Simple yet elegant, Callas provide a graceful addition to the garden that can be matched by few other flowers. Long-lasting blooms are produced in the spring and summer, and a single Calla bulb can produce upwards of 10 flowers every season.
Cutting Callas for use in indoor bouquets will not harm the plants. After blooming is finished for the season, reduce watering and allow the plants to dry out naturally. Callas are hardy only in Zones 10-11 and must be dug up and stored for the winter in perforated plastic bags with peat moss or vermiculite.
Callas can also be grown indoors in decorative well-drained pots. Plant the rhizomes in good quality potting soil the same as if they were being planted outdoors. Water well and place in a cool, shaded spot until foliage appears; then move to a location where the plants will receive about 4 hours of sun per day. Water regularly and let the foliage die back naturally after flowers have faced. Do not cut the foliage back as it is needed to strengthen the tubers for the following season.
