I've trialed a lot of groundcovers and made a lot of mistakes over the past 6 years in my efforts to find that magical plant that will cover ground and suppress weeds, but not be too aggressive/invasive or too much work to maintain.
Here are two promising evergreen / semi-evergreen candidates that have performed well so far. The fact that they are both native to this part of Tennessee is a big bonus.
|Packera obovata, golden groundsel, fully evergreen through this past (relatively mild) winter. |
(I tried growing another Packera - P. aurea - last year, but it did not seem as tolerant of heat and drought, even in partial shade, as P. obovata.)
