This is one of my favorite stores ever! They carry a wide variety of high quality plants at very reasonable prices. True, it's a little more than places like Home Depot or Walmart, but it really is a good idea to pay extra to get better plants.
The employees are very friendly and eager to help. When I was there last, one associate was kind and helped me look for a specific plant I was trying to find.
They also have a wide assortment of soil amendments, mulches, and all other gardening needs.
