Will Cala Lilies grow in the Texas Panhandle?

Answer 1

You can grow calla lilies outdoors in zones 7-10. A friend of mine grows them in large pots up here in New Hampshire. You *might* be fine growing them out in your garden where you live if you are in the southern third of the panhandle. If you're further north, grow them in large decorative pots and take them into your basement for a rest for the winter.

There are ways to get plants like this to grow. I used a pot to contain the rhizomes and retain water in the ground. Sink the rhizomes only 2-3" deep in the soil otherwise they will not flower. They can be spaced 6-12" apart depending on size of the final plant. Grow the plants with morning sun and afternoon shade or a full day of filtered sun. I grow mine under a locust tree, which is why I have the rhizomes in the pot or the tree will get all the water. They need to be kept moist.
The pots are large. I used an old muck bucket with a hole and an old wash tub I pierced for drainage. They prevent tree roots and keep the lilies well watered. Callas need to be kept moist so once the surface is dry to the touch water again. To prevent the tree from forcing an entry I lift the pots and turn them every year.
I believe the panhandle gets to cold for the lilies to survive over the winter. You will need to store the rhizomes in shelter to prevent their loss if the temps go below 20 degrees. You need to let the soil dry , remove the rhizomes, shake off excess soil, cut off the dead brown tops and lay in a single line in a box in a cool, dark, dry place all winter, as a partially heated basement. However they will only do this a few years so it may be easier to replace them every year.
These lilies came from South Africa so like the warmth but not the afternoon sun. They will grow well with Hosta or Elephants Ears (Caladiums) if you do a larger watered area.

I think so-- but you'll need a micro-climate. Check on the general growing instructions for calla lilies-- then provide those conditions.
For example-- here in Oklahoma City, they do grow-- my SIL has them on the east side of their brick home. I don't know the condition of their soil-- but I would provide what the lilies need--
I do not know if they have to be brought in for the winter-- again, general instruction information.
good luck
