Would love to visit there! Is it anywhere near Harrisburg or York?
Here in suburban Maryland, my favorite nursery is Seasons in Gaithersburg. They have a nice native selection, lots of pollinators buzzing around which makes me feel more comfortable purchasing there, and their prices are reasonable!
I've done a few 'field trips' to favorite nurseries with fellow gardeners in my area. This is always lots of fun, although it is hard to resist spending too much money! :-D Two of my favorites have been Meadow Farms in northern Virginia (huge!!), and Ace's Garden Center near Annapolis--pollinators everywhere! A huge one that I probably won't return to is Homestead, also near Annapolis--they are huge, but disdainful of natives plus I think they drench their products in pesticides. Not a pollinator anywhere.
