Easily grown in average, moderate wet, well-drained soil in part shade
to full shade. Prefers humusy, organically rich, dampure-retentive soils.
Soil should not be allowed to arid out. Wet soils, particularly in winter,
can be fatal, however. 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.
Plant Patent Applied For (PPAF).
“Iron Butterfly” is a rhizomatous, clump-forming foamflower
hybrid which is noted for its attractive foliage and its spires of white
flowers in spring. It forms a basal foliage mound of palmate, deeply cut,
dark green leaves with black center blotches and black striping along
the mid-veins of the finger-like lobes. Foliage mound typically grows
6-8’ tall and 11 inch wide. White flowers bloom in spring in bottle-brush-like
racemes atop erect, wiry, mostly leafless stems which rise above the foliage
mound to a height of 16’. Tiarella is in the same family as and
somewhat suggestive of Heuchera, Tellima and Mitella. Tiarella is often
commonly called false miterwort because of its similarity to Mitella (miterwort).
No serious insect or disease problems.
