I moved from BC to northern Alberta (definitely zone 2 climate) and into a brand new home. I am in the process of finishing the landscaping. The home came with a professionally designed landscaping plan. On the SE corning of the house (full sun all day), the landscape architect called for the use of a Picea pungens "Koster" to occupy a 10ft diameter area surrounded by a variety of shrubs. That corner is one of the lowest spots on the lots so much of the rain water from my house and my neighbour's house will drain into the area. Picea pungens "Glauca" is abundant in the area but I am afraid that it will outgrow the corner in no time. I have tried pretty much every local nurseries and cannot find a Koster anywhere. Pretty much the only way I can get a Koster here in Alberta is to pay an enormous shipping fee and get one shipped from Ontario or BC. I have been doing some research on finding an alternative to the Koster. I have a couple of ideas in mind but is wondering if others have any suggestions?
