I got my Lucky Bamboo at the .99¢ store. It's 3 small canes with not many leaves. I put it in a fancy drinking glass with rocks, from the .99¢ store, and water. One of our cats ate the tips off the leaves.
Then, I put it outside in the shade, just for the morning. Three days later, I remembered it. The sun had taken the Crayola green color away and the leaves were yellow. I figured they would die off and be replaced by new ones.
To my surprise, after being inside for a few days, the color has begun coming back to the sun damaged leaves AND new leaves are coming in.
The furniture has been rearranged and the cat has not been able to get back at the plant
. The cat is fine.
