I think it is interesting. Whenever I plant stuff with my homemade compost, I get lots of volunteer tomato plants popping up. No other weeds, just tomato plants. So this season I've been planting seeds/seedlings in my homemade potting soil with mushroom compost. And guess what, lots of volunteer tomato plants popping up. No other weeds, but quite a few tomatoes. Some that I didn't spot in time, since my seed starting area is getting crowded and bushy, turned into quite healthy looking little plants. I was almost tempted to save them, but since I've got seven varieties of tomatoes going, and I have no idea what variety(ies) the volunteers might be, I just composted them.
Tomato seeds must be exceptionally hardy! They are never visible to the naked eye in the compost that I plant with that ends up sprouting them. By the time that compost is planted, the seeds have probably been in there six months or more, been through the whole winter, been through the whole composting process, complete with lots of earthworms, pillbugs, etc digesting things. And yet put the compost in the ground and bingo! tomato plants! Amazing!
