Abstract
A new and distinct Hemerocallis cultivar of the evergreen type named ‘Endless Heart’ is provided. The new cultivar is very floriferous and forms attractive highly ruffled bright crimson red funnel-shaped blossoms over an extended period of time that commonly begins during mid-June and commonly ends during mid-September in U.S.D.A. Hardiness Zone No. 6. The blossoms possess substantial substance and well withstand rain damage in view of the strength of the tepals.
