Easily grown in average, medium, well-drained soil in full sun to part shade. Prefers part shade in hot summer climates. Does not do well when night temperatures do not consistently cool down below 70 degrees F. Needs regular moisture. Plants may be cut back to basal foliage after bloom. Divide clumps in fall every 3-4 years. Spreads freely by rhizomes under optimum growing conditions. This cultivar is sterile and accordingly will not self-seed.
'Kent Belle' is an upright, clump-forming perennial which typically grows 18-28" tall. Large, drooping, tubular, glossy violet, bell-like flowers (to 2" long) with inside spotting appear in terminal racemes atop erect to slightly arching stems. Stems rise up from basal rosettes of rounded, toothed, medium green leaves (to 5" long). Long late spring to early summer bloom. Light rebloom may occur in autumn.
No serious insect or disease problems. Can be mildly spreading.
Borders, rock gardens, cottage gardens, lightly shaded woodland settings or naturalized areas. Group or mass for best effect.
