I have a short row of assorted mixed heirloom tomatoes,. I bought the mixed packet as I don't grow many tomato plants, and don't know what I like yet. So, I don't know what variety I'm growing. I have them about 3' apart. My question is - if I grow a tomato that looks exactly like an Arkansas traveler picture, and I really love the taste, would it be safe to assume the seeds will grow an Arkansas traveler?
