First, let me suggest you ask this over on the Tomato Growing forum, where there are lots of folks who might be able to help.

However, at this time of year finding seedlings will be difficult, unless you grow your own. There just aren't enough places where tomatoes can be grown this time of year for commercial greenhouses to offer them.

Thus, you might be better off looking for seed, which you can then use to start your own.

Check with Laurel at this address.

I ordered mine last year from Territorial Seed Company. They were all very healthy and did well.

Here is a link that might be useful: Link to tomatoes

Rob,

Are you looking for plants for set out in the mid to late Feb time frame, which works best in your zone 10 FL for your Spring crop?

If so, then the many places that most here would recommend would not be useful for you except for the link Fusion gave you to Laurel who is in Southern CA.

Bonnie Plant Farms also distributes in your area and usua lly has a good selection. Check now with your big box stores to see what and when they will carrying heirloom plants b/c if you can determine what will be available and that satisfies you, then you can save lots on shipping from CA.

And do consider coming over to the Tomato Forum, link at the top of this first page, to read much more about t omatoes in general and heirlooms in particular. There are many FL growers who post there.
