You can get some interesting plants from them, but the focus is not what it used to be, IMO. Rather than selling inexpensive plants for the sake of getting them out there and planted, with the resultant environmental benefits, the focus now seems to be as a fundraiser for their activities. Nothing wrong with that, but shop wisely. I've seen some plants go for prices that were no bargain to be sure, and others that were extremely small, especially for the price. I remember the days when you could get dozens of tree seedlings at next to nothing, just to encourage the planting of trees. In fact, it used to be a problem sometimes wondering where to plant the minimum numbers of two dozen or so of each species, when all you wanted were a few of each.

Patrick, it's true that the sale is a fundraiser - after all conservation districts (in Mass, I don't know about elsewhere) receive no financial support from the government. And their focus IS starter plants, as not everyone can afford to install a camera ready garden!

But most perennials this year are $4 or 3/$10, many natives - I'd have a hard time finding those prices at my local garden center. Here's a few highlights of the natives available this year, from the website:

Aquilegia canadensis, Chelone obliqua, Echinacea paradoxa,
Tiarella wherryi, Penstemon barbatus

and for trees/shrubs
Betula alleghensis, Cephalanthus occidentalis, Cornus alternifolia, Craetagus phaenopyrum, Fothergilla gardenii, Halesia carolina, Ilex verticillata, Itea virginica, Rhododendrons rosebay and catawbiense, Sorbus americana.

All the sizes are listed so there shouldn't be any surprises for people ordering - you know exactly what you are getting!
