Dwarf fragrant sumac is a low-growing native shrub with yellow flowers in the early spring and has scented bark and foliage that are responsible for its name.
Low-growing phloxes have a cool color palette made up of lavenders, purples, pinks and whites.
Ajuga is hardy zones 3-9 and prefers light shade and evenly moist well-drained soil.
Liriope muscari has grassy foliage and spikes of blue or white flowers in the heat of late summer. It is especially accommodating as an edging or groundcover and there are some varieties with handsome variegated leaves (eg ‘Silvery Sunproof” ).
Many white flowers bloom in May, but the tiarella is one of the only ones to bloom so prettily in the shade.
The leaves of Georgia Blue Veronica are small and dark green and turn a burgundy-bronze shade in winter.
