We have just a few farmer's markets around here, and I don't think too many gardeners sell plants at them. I've participated in a few plant exchanges. You can take home as many plants as you bring, but often don't get much beyond the common stuff you already have!

Ah, Stuart - for some of us a dividable plant or extra seedling is like love - we don't charge for it, we just give it away!

There's an annual plant sale in the park of the village where our school is located, but I haven't been to it. I probably should check it out.
I buy my plants from 2 favourite nurseries mostly. And as Annie says, I give things away...never sell them....and occasionally am lucky to get a few free plants in return.

I'm with you Annie. I love to give away my plants as well. The plant exchange sounds like an interesting idea but my misgiving would be the same as yours - you just keep perpetuating the same common plants.

I'd still love to hear from those people who do sell their plants as a hobby-business.

I've never sold my plants but I have participated in plant exchanges with the Master Gardeners and donated plants to them for sales and auctions.
