Our Calla Lilies
Our Captain Calla Series started to become one of our company signatures in 1992. Growing and breeding Calla Lilies proved to be a unique challenge, but one that we were up for. Nearly 30 years later, the industry recognizes us as “the Calla people”.
As breeders of Callas, we believe that ‘New’ alone is not good enough. We work on improving our Calla assortment every day and we have been successful! The Captain Calla brand is known worldwide.
Captain Calla’s are decorative tubers that can be grown indoors or outdoors. It is easy to care for and looks great grown in groups, in flower beds, planted in pots, or as a table centerpiece. The Calla’s exotic Spathe lasts an entire month and is an in- and outdoor eyecatcher!
Where Calla Lily Bulbs Grow
The Calla Lily is native to South Africa where it grows on sites where it has to tolerate both wet and dry periods. This explains why calla lilies are such strong plants.
Calla lilies are winter hardy in zones 8-10. In colder areas, they can either be grown as annuals or can be dug up in the fall and stored indoors for replanting the next spring. In warm climates, calla lilies grow well in full sun or partial shade. In cooler areas, they grow best in full sun.
What are hardiness zones? Ranging from 1 to 13, a hardiness zone is just the range of possible temperatures in a geographical area – specifically relating to plant growth. The lower the number, the colder the possible temperatures, and the higher, the hotter.
How to Plant Calla Lily Bulbs
Where to Plant: Our Calla Lilies are suitable for planting in zones 7 – 10 and they need full sun but will tolerate partial shade (up to 25%)
How to Plant: Summer bulbs, corms or tubers are planted at a depth twice as deep as the bulb is tall. Begonias and dahlias, however, are exceptions since they should be planted just below the surface. Arrange small varieties 4 inches apart; this is a good distance for them. The distance apart for dahlias is 5 inches, for begonias 25 cm, for lilies 30 cm and for dahlias even 40 cm.
When to Plant: Planting can start in April but should wait until the risk of frost is past. If cold winter temperatures continue long into spring, planting should wait a while. You can plant summer bulbs until the end of May.
