Half Barrel Planters
I'm doing a landscaping project for a friend of mine. I'm helping him figure out what to plant in a flowerbed and he also asked me to help him figure out what to plant in these two half barrels on either side of his driveway. For some reason he would like perennials in both of them. Do you have to chose plants that are one zone or two zones colder than you are for containers? Since we are zone 2b that means that I should be selecting plants that are zone 1 or even zone 0. Which plants fit into that category? I was thinking of planting an evergreen in each of them plus something else that would hang over the side. That is what I've come up with so far. What type of evergreen I don't know, same with the plant that would hang over the side.
So, any suggestions as to what plants I should plant in them? Or should I just tell him he is stuck with annuals?
