Tiarella’s are beautiful, low-maintenance shade natives that thrive in a woodland garden – tough, evergreen and tolerant of the deepest shade.
Semi-glossy, heart-shaped, 3-5 lobed leaves may have reddish variegation along the veins. Foliage is evergreen in mild winters, often turning reddish bronze in autumn and winter (consider it “semi-evergreen” with our winters.) Tiarella have racemes of tiny, white flowers. Long stamens with a foamy appearance give rise to the common name of foamflower. Flower buds are pinkish.
‘Elizabeth Oliver’ is a beautiful selection with a tidy clumping habit, deeply-lobed, light green leaves with heavy maroon markings and delicate, fragrant flowers tinged with pink. ‘Elizabeth Oliver’ is clump-forming, but may spread slowly by runners.
Tiarella prefers humusy, organically rich, moisture-retentive soils. Soil should not be allowed to dry out. However, wet soils, particularly in winter, can be fatal.
