The Fairegarden loves the concept *Sea Of* (insert your choice here). Right now the seas are composed of shades of blue, like the Veronica umbrosa ‘Georgia Blue’, a groundcover planted in the angel corner, at the end of the middle terrace pathway.
The blue grape hyacinths that were inherited with the property are everywhere, seeds scatted by the wind and bulbs transplanted by human and four legged diggers. Perhaps these are Muscari armeniacum, maybe M. neglectum, it doesn’t really matter, they are a large body of water planting that gets better with each passing year.
Another pioneer is the sky blue Vinca minor. It provides a service by keeping the bare ground covered and weed seeding to a minimum. Other plants and shrubs have no problem growing up through the evergreen dark, shiny elliptical leaves.
