Choosing the right sun ground cover plant that will thrive in the medium offered is essential for any home landscape gardener. So you have to do some preliminary research, but you will certainly be compensated in the end. For example, it is best to know the type of soil in the garden and the approximate number of hours of sun the land receives in spring and summer.


Crown Grass (Lysimachia nummularia)

Aside from pH, a factor to consider before planting is the soil’s ability to hold water. Usually, a full sun ground cover perennial is drought tolerant and needs well-draining soil.

The good news is that the majority of full sun ground cover plants require very little maintenance. Keep in mind, however, that some species can be invasive. Therefore, it will be necessary to cut them every year to prevent them from completely taking over the garden.
