Ran Lydell of Cooks Nursery and Eagle Bay Gardens in New York registered this fast growing cultivar of unidentified parentage in 2001. It is a medium size plant that grows about 14 inches tall and spreads about 35 inches in diameter. The leaves are heart shaped, slightly corrugated and of average substance. Pale purple flowers are borne in clusters on fasciated (thickened) scapes from late July into August.

The MyHostas Database website says that 'Oh My Heart', "...is probably the heaviest blooming hosta we've seen anywhere..."
