Need help selecting a groundcover plant
Just built a flowerbed over the weekend. There used to be this large pit in the ground at the northeast corner of my backyard, and I filled the pit with mostly your dear old Colorado's clay soil, mixed with gardening soil - the pit was way too big to be filled with only gardening soil, I'd be broke buying gardening soil. I planted two Lowe's-bought Forever & Ever hydrangeas in the flowerbed.
I need some groundcover plants to cover the rest of the surface of this flowerbed:
- The soil is clay-like. Groundcover must be tolerant to that.
- The flowerbed is in the northeast corner so it only gets partial sun.
- It is right next to the fence so I don't want something that can easily spread into my neighbor's yard (no no to periwinkle or anything that creeps) or my own backyard lawn.
- The groundcover cannot be so competitive that it takes over my hydrangeas.
- Obviously I will have to water the hydrangeas as much as they need. I hear sedums and iceplants spread out of control if they get enough water, so those may not be viable options either.
- The shorter the better, something shorter than 6".
- I am lazy so I prefer groundcover plants that don't need winter protection.
- I am willing to reseed every year but prefer not to (again, lazy).
- I don't care if the groundcover is flowering, or what shape/color its leaves are, or if it is evergreen, etc. Just want the groundcover to protect the soil from erosion and weeds; no ornamental purpose intended. Of course I wouldn't mind if I did get something pretty!
I know mulch meets all my needs but it'd be too boring... Your suggestions and recommendations are highly appreciated!
