We have four pet rabbits in our yard that run loose and eat whatever they find growing. I am about to plant three large bulbs of elephant ears in the shady part of our yard. Will the plants survive the rabbits with protective fencing until they are large? Will the rabbits survive if they get to them and consume the bulbs or leaves? I don't want to kill the rabbits and I can plant them in pots if need be.
Yes, the protective fencing should help. Toxicity will depend on the species of Colocasia or Alocasia you have. The name 'elephant ears' can refer to several similar-looking species. I'll assume that you have Colocasia esculenta. This plant is not poisonous when it has been properly cooked. I doubt that the plant would kill your rabbits if they ate it raw, but they may suffer irritation in the mouth, throat, and stomach from it. I'd keep the rabbits away from it.
How long after planting should I see a sprout?
Your Elephant Ear bulb will take about 3 weeks growing roots before you will see any growth above the soil.

What is this yellow rolled looking leaf that has yellow powder? Usually a rolled green leaf comes out and unfolds a new leaf.
Is it possible that the yellow rolled leaf with yellow powder is actually the developing flower of the elephant ear? Here is a photo of what an elephant ear flower looks like:

It's the only explanation I have for the "yellow powder" because the flowers will have yellow pollen. If that's not what it is, please send me a photo for identification.
Can you leave plant in ground year round?
It depends on what your winters are like. Freezing temperatures will kill the tubers underground (which will kill the entire plant). This article provides some tips on overwintering them:

Instead of the usual large leaves, it now has more smaller leaves and they are all drying out or turning yellow. I sprayed the plant with some Miracle Gro disease and mite control, as I noticed some white powdery stuff on the trunk area. I need to save this plant.
Check the watering of your plant.
Elephant Ear needs high humidity and you can run a humidifier in the room.
A bright sunlight is needed, but avoid direct sun.
Neem Oil is a good treatment for pests.
This may be Mealybug on your plant.

I over-wintered my upright elephant ear plant by cutting off the leaves, then digging it up and storing it in a pot in the dark, cool (but not freezing) basement. When I replanted it outside, it immediately started growing, but has produced only blooms/seed pods, and no leaves. What have I done wrong? Will it produce leaves later? I live in north Alabama, I think in zone 7. Thanks! Pam
Side note: you should know that seed pods are rather rare in this plant, so you may want to save them and create new Elephant Ear plants. This article will explain how:
https://www.gardeningknowhow.com/houseplants/alocasia-plant/elephant-ear-seed-pods.htm
This "could" be a result of not cleaning off the "bulbs" (tubers, or corms) when you dug the plant up for overwintering, or it could simply be your plant's reaction to your current spring weather conditions (your plant may be trying to "catch up" by sprouting seed pods if you had a slow start to spring this year). It would be very odd if the plant produced no leaves at all, so it's likely that given enough time and the right growing conditions, it will sprout leaves. It's still early in the season -- keep an eye on it for a couple more weeks to see if it sprouts leaves.

I dug up see bulb plants because they had to be moved or tossed out. Elephant ears, cannas, and Peruvian daffodils. Can I just transplant them or put them in pots?
In the case of the Daffodils I would dry and store the bulbs until fall, then plant out.
Where the Elephant Ears and Cannas still actively growing?
I would pot these up and either continue care or allow the foliage to dry down naturally to feed the bulbs.
Then store as per the articles below.
