Q.Verbena
Have a stump I want to place a potted verbena on so it can eventually cover around it. The stump is flush with the ground. Ideas?

Verbena can be grown as a perennial in zones 5-10.
You could plant directly in the ground and over time it could fill in the area and disguise the stump.
Planting in a container would not likely be successful in the long run.
Here is a link with growing information.
