The new and distinct hybrid of Heuchera plant named ‘;Timeless Night’; with small to medium-sized, shallowly-lobed, glossy, greyed-purple leaves with rounded apices and lobes. Numerous, moderately-branched, upright, dark-purple flower stems are repeatedly produced from early summer to early fall for about fourteen weeks displaying small, rosy-pink flowers starting just above the foliage. The habit of the new plant is compact, herbaceous perennial with mounds of leaves. It is vigorous and produces showy flowers over a long season, effective as a specimen plant, en masse in the landscape, or as a container plant.
