I have a whole bunch of tropicals: canna, caladium, colocasia, and begonia that I started in pots inside to get a jump on the season.
Dover likes to play with his tennis ball inside, tossing it in the air, and occasionally it will land in one of the pots, and of corse I check for damage and give him back his ball. (Those of you with smart mischievous dogs know where this story is going.)
This morning he jumped up on a cedar chest, ball in mouth, waited for me to make eye contact, then walked over to the end and dropped his tennis ball into a pot of Canna lilies. Then he turned around and looked back at me tail wagging... like "go get it mommy... get the ball..get the ball! Good girl! ". He figured out if he drops his ball into my plants, I'll throw it for him.
