Heirloom tomatoes are awesome and you should grow some. Seriously, if you've never tried this type of tomato, you are going to be sooo excited come July and August. These tend to be more expensive, but they're only in season for a very short period of time and it's well worth it. Plus, they're cool looking.
So, yeah, it's not time for Heirloom tomatoes to start showing up in the markets just yet. But - if you have a garden or a patio/balcony where you can put a pot and grow some tomatoes, this post is for you. Sadly, I have the opposite of a green thumb, whatever that is (a black thumb?) so I won't be killing any tomato plants this year. But you should! Seriously, do it.
You can get certified organic seeds from Sur La Table. Yeah, I know, it's a chain store, blah, blah, blah, but these seeds are not only organic, but they come from a family farm in California. It says so right here. These guys should be giving me commission on this! I just got excited when I saw this and wished that I could actually grow things. I'm sure someone out there might want to. :D
