Calla Lily Seeds ,White Giant, Perennial

The White Giant Calla Lily is a South African native that yields impressive, 10-inch white blooms with a creamy yellow finger-like center. It is a hardy perennial suitable for gardens and containers in zones 7-11, blooming from late spring to mid-summer.

Calla Lilies (Zantedeschia spp.) have wide emerald green leaves and tall spathes filled with white flowers. They bloom in the early and midsummer, then produce seeds in the late summer and early fall. Calla Lilies thrive in USDA plant hardiness zones 8 through 10soak in cold water and allow to sit for 24 hours

Germination: Scatter on the surface and lightly cover with vermiculite. Plant in temperatures of 70-75F (20-25C). Do not block out light.

Fill 3-inch seedling pots with a standard potting mixture and set the pots in a drip tray. Sow the calla lily seeds on the soil surface and press them into the soil so the top of the seed is just barely exposed.

Pour one inch of water into the drip tray and allow the soil to soak up the water through the bottom drainage holes in the pots. Pour out the excess water when the soil surface feels moist, which can take up to an hour.
4
Cover the pot with a clear plastic bag to retain the moisture in the soil and air as the seed germinates. Set the pot in a 70 to 75 degree Fahrenheit location where it receives bright, indirect light. Calla lily seeds require light to germinate.
5
Monitor the soil moisture and water lightly if the soil begins to dry before germination. Remove the bag once the seeds sprout, which can take between one and three months.
6
Move the pot to a location that receives six to eight hours of direct sunlight after the seeds sprout. Water the calla lily seedlings when the soil surface dries.

Transplant the plant into a 6-inch pot after the seedling produces its second set of true leaves. Plant it at the same depth it was growing at previously. Choose an acidic potting mix, such as one formulated for azaleas.
