Small bed with water line under it
There is a space between the house and patio, about 2-1/2 feet wide and 10 feet long. The water line to the house is in there, about 2 feet deep.
When we moved here, the last owners had planted boxwood there and I took them out and put in canna. Those didn't stay there long before I took them out and tried some shorter herbs and flowers.
The problem with the area is that it receives runoff water from a roof valley so whatever is there needs to be able to stand in water for short times and then have regular weekly watering.
For the last several years, I've just had rocks and gravel there, but would like to make it a focal point for my courtyard, so I'd like to plant something. But it can't be anything aggressive that will spread into my adjacent dry stream.
Any ideas? I'll post a picture if that will help.
