Unless they were cross pollinated by something else.

There are a number of cultivars with Brandywine as part of their name so it would depend in part on exactly which one you planted. But the odds are approx. 9:1 that they will be true to what you planted there last year.

How many plants in what you call your Brandywine bed and how far from any other tomatoes you were growing?

All to say that I agree with Dave, and wanted to add that each year I used to dig up maybe 10 volunteers and plant them in a differrent place and then tried to ID them, even when I knew from my plot plan what I might have expected.

I seldom could ID the volunteers.

When fruits drop to the gound in the Fall,some of those seeds are availableto birds,who love them, and they can deposit them in places far away from where they got them from.

So no way to know what you might get until you grow them out.

Some varieties with Brandywine as part of the name have PL foliage, some don't, and you can't even go on that for a possible ID if someof the seeds in the Fall were X pollinated, as Dave said.

But do share with us which specific Brandywine you grew in that bed last year.

Carolyn

Oh, what happened to my botany knowledge? Of course! the seedlings have 2 parents, so with the other tomato varieties only 4-8 ft. away from the Brandywine (don't know specifics of cultivar; bought the seedlings at a local plant & flower store), the chances are good that the babies are all a mix. Right now the 3 inch high seedlings don't have typical potato-leaf foliage. I'll save a couple and plant them at the end of the newly located tomato bed, and we'll see.

Thanks for your advice.

Carol, if some of your volunteers are Bandywines, then they are OP and stable and don't have two parents.

But if some of your volunteers turn out not to look and walk and talk as a true Brandywine would, then it resulted from X pollination and would indeed have two parents.

Without knowing if your original plant called Brandywine was true Brandywine with PL foliage or Red Brandywine,which has RL foliage, I guess you are in for a mystery. ( smile)

Let us know how it all turns out.
