Q.Containerizing Shrubery
Hi there — can firethorn bushes be containerized (larger pots)? Or are they strictly “in-ground?” Can you recommend other perennial shrubs that can be containerized? I have a friend who does well with boxwood and a spruce shrub. I live in Colorado and we have for many years put lots of annual flowers in pots on our courtyard, but the past three years they have all been destroyed by early hail. We are tired of the expense and work of replanting the flowers twice in the Summer, and are seeking alternatives.
Thank you!
Patricia

Firethorn is actually an excellent shrub in a container. With a little pruning you can even create some interesting shapes. Add a trellis or turret to the container to create an eye catching display.
Here are some links with more information and some other options for your zone 5 garden.
