Which ground cover is NOT recommended for the South?

The choice of daylily as a ground cover is not recommended for the South because, while they are often valued for their beautiful blooms and drought tolerance, they do not perform well as a ground cover in many southern regions. This is due to their growth habit; daylilies tend to grow in clumps and do not spread out to effectively cover ground. They are better suited as individual perennial plants rather than as a carpet of ground cover.

In contrast, the other options like English ivy, Ardesia, and Indigo can provide better ground coverage due to their spreading nature or ability to thrive in the southern climate conditions, although English ivy, specifically, can become invasive if not managed properly. These alternatives can fill in spaces more effectively and offer the soil protection and aesthetic appeal that ground cover plants aim to provide in southern landscapes.
