Golden creeping speedwell (Veronica repens 'Sunshine') sure knows how to brighten the day. This sweet little groundcover forms a half-inch (not even) mat that serves as the perfect backdrop for a red lettuce, Helmond pillar barberry (Berberis thunbergii f. atropurpurea 'Helmond Pillar') or black mondo grass (Ophiopogon planiscarpus 'Nigrescens'). Or heck, why not all three. This super, simple plant needs plenty of sun to be at its brightest; mine starts heading toward chartreuse in the least bit of shade. It spreads slowly to form a carpet of shimmering gold that's sure to catch the eye. Oh yeah, tiny purple flowers too (sometimes) in spring.
