You're a gardener? That is so interesting. I have never had a green thumb. One time I killed a cactus, well it was the neighbors cactus, I kinda ran it over with the lawn mower, the neighbors don't like me much, they tell my roommate that I am a bad influence, I mean how was I to know that SCUBA tank had enough air in it to go through their front door? I'm getting off subject. I see that you are a Botanist.
