Most local farmer's markets will have plants. Triad Farmer's Market is great. If you are looking for an actual greenhouse, the best I know in this area is Myer's Greenhouse on Highway 158 between Clemmons and Winston Salem.

Most nurseries in this area have some natives, but to get natives at a great price come to our NC Native Plant Society picnic near Greensboro. We have a 10:00 instructional meeting, noonish potluck (bring sides or desserts) followed by an auction of plants. You never know what will be offered, but there are always great plants, and the funds collected go towards scholarships. See details below. You are near the site.

PS: Most of my Greensboro friends and I go to Niche Gardens near Chapel Hill. They are about 95% native and have great selections. You should visit this spring.

Just wanted to second ncrescue regarding Niche Gardens. It is Exactly what you appear to be looking for. As I recall, many of their plants are in a woodland setting. While Niche isn't in the Triad, it is at least on the West (and south) side of Chapel Hill.

How much do the plants tend to go for at the auction? That sounds like fun! :)

It all depends on who brings what, but in the last few years, we have had quite a few of the more common plants, so they are set aside in a $3 or $5 section, honor system and no auction. Sometimes there are $1 plants as well.

The larger plants and those harder to find in the trade can be pricey if people bid against each other. This usually happens when someone brings an unusual Trillium or something that you normally cannot find in the trade around NC.

But, I would say $5 - $10 for many of them. Yes, it is fun, and proceeds go to scholarships for people who study botony, ecology, etc.

Thx! :)
