So, if you are looking for an instant horticultural education, google is your friend. Or, download one of the care sheets from his website. Or try YouTube. Shamus runs a pretty-close-to-one-man-operation. Long drawn out conversations and endless questions about basic gardening techniques are inappropriate for this kind of business. If he comes across as blunt and not interested in spending 45 minutes with your "teach me how to garden, because I haven't done any research on my own" questions, there is a reason for that. Additionally, this isn't Home Depot. You do have to call ahead. Mostly because a huge percentage of the business is seasonal, and on weekends. If you want someone to be your new best friend and hold your hand for an hour while you make up your mind between two identical plants, go elsewhere. If you want the best selection in AZ, this is the place to go.
