Is my Hilo Beauty elephant ear plant dead? I bought it in packaging. When I opened it, I noticed the brown bulb with brown roots (not pink or fleshy) and a cut, black central stem. I decided to plant it. Now I'm thinking. And worried. The package even said "Guaranteed to Grow." Sure hope they are right...
The description sounds like a normal Elephant Ear bulb.
As long as the bulb was firm with not soft spots or rotting, it is likely a healthy dormant bulb, just waiting to be planted and will began to grow with proper planting, moisture and light conditions.

How far do I plant this bulb in ground?
I believe that you have a Colocasia bulb. There are several plants that are given the name of Elephant Ears. They are all in the arum family. In the Colocasia group there are clumping and running forms--the runners are called stolons.
Your bulb looks to be one of the running Colocasia bulbs.
These bulbs should be planted 8-10" deep.

I planted a Mammoth Elephant ear bulb 3 weeks ago in a pot inside. It didn't come up. It didn't have a what they call pointed end...both ends were flat. Will it still grow if it was planted upside down? How long does it take one to come up? Someone told me it takes 3 weeks, but mine still hasn't come up yet.
The top of the tuber should have a series of rings visible. Small bumps are also generally visible.
The bottom of the tuber is generally more rough looking, with pocks and craters.
These large tubers generally take their time in appearing, it may be 3 to 4 weeks before it wakes up.
Make sure you are watering correctly and that the bulb is in warm and bright location.

I bought elephant eat bulbs about 2 years ago and never even opened the box to plant them. Are they still good to plant?
Here is an article that discusses the shelf life of flower bulbs. The quality of the flower decreases with each season the bulb does not go into the ground, however, I would not let that deter you. I would recommend planting the bulbs no matter what - you have nothing to lose and might get rewarded!

I planted the bulbs a week ago. They haven't started sprouting yet and we had an unexpected frost overnight. How do I tell if the tubers are damaged?
It can take Elephant Ear bulbs 3 weeks to sprout. They are a large bulb and take time to wake up.
If the ground is cold and you see no signs of sprouting, the bulb may have suffered and it could be damaged beyond repair.
Bulbs can be started indoor 3 to 4 weeks before the last frost to give them a head start.
If you don't see any signs of life from your bulb, I would dig it up and check the condition.
If it is soft and mushy, it should be thrown away.

What size pot should I choose for Elephant Ear/Colocasia? I live in MA.
Elephant ear needs room to grow and can become a very large plant, so you can cut to the chase and put it in a large pot (20-36 inches wide).
