Culture
Easily grown in average, medium moisture, well-drained soil in part shade to full shade. Prefers humusy, organically rich, moisture-retentive soils. Soil should not be allowed to dry out. Avoid wet soils which can be fatal particularly in winter. Removal of flower spikes after bloom will improve the appearance of the foliage mound. Foliage is semi-evergreen in the St. Louis area where the amount of retained foliage color in winter, if any, is in large part dependent upon the severity of the temperatures.
Noteworthy Characteristics
Tiarella is a genus of about 7 species of herbaceous perennials from East Asia and North America. They make good ground covers in woodland gardens and shady borders.
Plants are in the same family as and somewhat suggestive of Heuchera, Tellima and Mitella. Tiarella is sometimes commonly called false miterwort because of its similarity to Mitella (miterwort).
Genus name comes from the Greek tiara meaning a small crown in reference to the form of the fruit.
'Inkblot' is clump-forming perennial which spreads rapidly by runners (stolons) to form dense, 1-2 foot-wide clumps of foliage. Semi-glossy, heart-shaped, 3-5 lobed leaves (4" across) rise directly from the stolons and are somewhat suggestive of Heuchera. Each dark green leaf has a distinctive dark purple to black, inkblot-like, center blotch. Tiny, pale pink flowers in airy racemes bloom in spring for about 6 weeks on numerous, erect, wiry, mostly leafless flower stems which rise well above the foliage clump to a height of 10-12".
Problems
No serious insect or disease problems. Watch for powdery mildew. Susceptible to root weevils and slugs.
Uses
Excellent selection for shaded areas of rock gardens, woodland gardens, border fronts, naturalized plantings or moist areas along streams or ponds. Mass for an attractive ground cover. Containers.
