This is a Big Zac tomato. I got the seeds from another NGA member

Home grown tomatoes are weird. One of my plants makes conjoined twins.

I have occasionally gotten a weird fruit like that with one tomato fused on top of the other.

fused blooms cause fused fruit. I get a few every year, it seems. For me, it seems to happen with heirlooms most often.
