Massive, peony-like double blooms open slowly and grow more beautiful by the day, bringing a rich, shifting palette to the spring garden. Tulip Callahan unfurls to reveal slightly fringed petals in dramatic tones of coppery orange and warm caramel, against lush green foliage. Blooming from mid to late spring, it pairs beautifully with other spring blooming bulbs and also shines as a long-lasting cut flower.
