Question
Do you have experience with hypericum moserianum tri-color?  If so, does it need deadheading or pruning to produce its yellow flowers all season? If so, will it go dormant in the winter in Zone 7, or just start looking ratty? Also...in terms of maintenance, which do you think would require more "spring cleaning" as a small-scale groundcover: the hypericum or liriope?

THANKS!
