Garden works in north vancouver is our local go-to garden spot that has a good selection of plants and flowers. During the fall they have great plants for sale that you can plant and then see flower the next year. The workers all have a great knowledge of their stock and other plants. I have only had one negative experience there- the store manager is very serious. No smiles or small talk. But she is very knowledgeable so as long as you're not scared to approach her she can be quite helpful.
