Introducing the darkest colour of the COLOR SPIRES® Series, with flowers so rich and vibrant, they glow! Indigo blue flowers are held in dark calyxes and are produced on top of a vigorous, bushy mound of foliage. Indiglo Girl is intermediate between S. nemorosa and S. pratensis and has the best of both worlds: large, brightly coloured flowers with the excellent foliar canopy. This fabulous variety matches the bloom times as the rest of the series, so you can display all the colours at once. This will rebloom later in the season if deadheaded.
