" 'Red Prince' is a dense, upright, oval-rounded, deciduous shrub that typically matures to 6-9' tall and as wide. It features funnel-shaped red flowers (to 1.5" long) that bloom in mid to late spring, with a scattered and much less significant repeat bloom sometimes occurring in late summer to early autumn. Flowers retain bright red color as they age, rather than fading to dull red with purple tones." (Missouri Botanical Garden Plant Finder)
