Patio Perrenial Container Ideas

Asked May 24, 2020, 7:34 PM EDT

Hello-

I have two larger containers on my covered patio that I planted hydrangeas last year. I knew there was a chance they would not come back and so far there is no new green growth on them. Does that mean they are probably goners?

What would be good plants to replace them with? I prefer perrienials and possibly something that blooms with some color.

Arapahoe County Colorado

CSU offers this Fact Sheet on container gardens with some good guidance on plant selection:

Most perennials rarely make it through the winter months without appropriate protection. Prune off several stems and if there is no green, the hydrangeas did not survive.


Perennials planted in outdoor containers can be risky. Roots that are above ground are not insulated enough to survive. There are several different things you can try that may increase the chances of helping perennials survive winters in containers:


Select perennials that are several zones colder; in the case of Arapahoe County, this would be selecting perennials that are hardy to Zone 2-3.


Move containers in an indoor shed or garage. Make sure to keep them watered during the winter months. Even dormant plants need water for their systems.


Containers can be moved to a protected space in the yard, especially away from winds. Group containers together for added protection. It is a good idea to wrap the containers in insulated blankets and even put mulch around the plants. Again, check soil moisture frequently.

Some homeowners plant the perennials in the ground for the winter and mulch well, but this would need to be done in September. Adhere to the CSU recommendation for winter watering of the landscape (including these perennials) during times of no snow.

Using perennials in containers requires extra care and protection throughout the winter or the plants need replaced each year. This is why—for Colorado—less expensive annuals are a much better choice for container plantings.

I meant to convey that most perennials PLANTED IN CONTAINERS rarely make it through the winter months without appropriate protection.
