<i>Hemerocallis </i>plant named ‘Sound of My Heart’

Abstract

A new and distinct Hemerocallis plant named ‘Sound of My Heart’ characterized by winter-hardy compact habit with clean medium-green foliage that goes dormant in the winter. The flowers are rounded, fragrant, single, pastel-pink, with a wide wine-purple band and matching picotee edge and yellow to light green throat. Outer and inner tepal sets are slightly reflexed with the inner tepal set having consistent, considerable, wine purple crisped margins. The new plant flowers on stems up to 70 cm tall with four-way branching beginning about mid-July and repeating into October.

Fruit and seeds have not been observed; Disease and pest resistance and tolerance: ‘Sound of My Heart’ has not shown resistance to diseases and pests beyond that common for daylilies, and given the northern testing regions the new plant has not been exposed to daylily rust, Puccinia hemerocallidis. The plant grows best and shows best coloration with plenty of moisture, adequate drainage and light shade during the hottest period of the day, but is able to tolerate some drought when mature and direct sun without leaf burn when provided sufficient water.

(5) Hardiness at least from USDA zone 3 through 9, and other disease resistance and tolerance is typical of that of other daylilies. The new plant is useful for landscaping en masse, as a single specimen or small groups.
