When do I plant Calla bulbs in Dallas, Tx? Also, plants left in ground in winter have not come up.

Planting of Calla Lily can be either spring or fall in zones 8-11.
I would give the bulbs a bit more time to wake up.
Calla Lily sometimes do not preform as well as one would like in warm zones and will benefit from lifting and storing to make sure they have a dormancy period.
Look for bulbs that are specific to warm climate growing.
