Matrix planting: groundcover

Lots of rain and relatively warm temperatures are giving us a lush spring. Here is a groundcover matrix of Equisetum arvense, Ajuga, and Lysimachia nummularia making a pretty grouping. The Equisetum will vanish within a few weeks, the Ajuga foliage will likely be hidden under the Lysimachia. I wonder what this will look like in July?

This is a thick but delicate carpet, easily crushed by footsteps. Larger perennials have no trouble emerging and growing to comparatively towering heights, so there may be a general decline once the shade of the larger plants becomes a competitive factor.
