I'm a fairly novice gardner and would like your suggestions for plants that can be used for planters/urns. I read some of the posts by Chico and Artsy which said Lobelia's, and supertunias are good to use.
What plants can you use to gain height in a planter? I don't want to use evergreens. Can you use prennials in planters? If yes, how do you winterize them?
Thanks for your help.
