QUESTION: What groundcovers can be used that will allow daffodils to come up in the spring?
Several plants used as groundcover permit spring-flower bulbs to grow through. Nashville-area garden specialists offer a few recommendations:
Ajuga, or bugleweed (Ajuga reptans). To some people this is a nice groundcover, to others it’s a weedy nuisance. It can be aggressive, but in the right spot it might be just what you need.
Periwinkle (Vinca minor), grows in shade, is green all year, and has pretty blue or white flowers in spring. Please note: Vinca minor is listed among the invasive exotic plants in Tennessee. Please use responsibly.
Daffodils will also push up through English ivy (Hedera helix), but because it, too, is an invasive exotic that can climb trees and displace more desired species, I would never suggest planting it in the landscape.
