Everett has a basket of dried pinto beans in our living room that he'll play with every now and then. Sometimes I'll step on a bean that was embedded in our carpet and toss it back in the basket. I must have been lazy one day because I tossed one in the plant by the fireplace... and it sprouted.
I took these pictures yesterday morning and now it's about 8 inches long. I guess that's what happens when your house is warm and sunny!
