So apparently you can cross a tomato plant with a tobacco plant.
My mother is working on something similar. It's a cross between coffee and a potato.
She uses coffee grounds from Starbucks as compost and puts it on the garden religiously. The garden -- both front and back -- smells great. You may not know this, but your local Starbucks will actually give you a huge bag of their used grounds if you ask nicely.
I haven't come up with a name for this hybrid yet.
