The "Red Robin" variety already mentioned is a good one for containers. A few others (all are determinate varieties) that many growers have success growing in containers include: 1. Lime Green Salad - (Open Pollinated) attractive lime green 3-5 ounce fruit that ripens to amber and is very early....about 60 days from transplants in zone 7. The plants are dimunitive and produce a good harvest. Fruit's taste is spicy, tangy. 2. Siberia - (Open Pollinated) Combines small size (self-supporting plants don't exceed 18" as a rule) and ability to set fruit at low temperature (reportedly as low as 38 degrees Farenheit. Fruit is early (about 60 days) uniform in size and shape, bright red and weighs about 4-5 ounces. Fairly widely grown and often included as a benchmark variety in growing trials for early tomato varieites. 3. Micro-Tom - (Hybrid) Claims to be to the world's smallest tomato plant. Plant only grows between 6-8 in height. Fruit is red and the size of a pea. Flavor is OK but nothing to write home about in my opinion. But if you're limited to a windowsill for space, it's a keeper. And then there's Sweet Million (hybrid), Tumbler (hybrid) and others. Am only listing ones that I've grown. Catharine/Atlanta, zone 7b
