This series offers a wide range of colors for spring or fall production. The XP varieties offer greater uniformity in plant habit and a tighter bloom window.
Delta is a grower favorite for good reason: The series combines large flowers, extra-early flowering, extreme uniformity across all colors in timing and habit, and outstanding heat tolerance. Delta blooms early in low-light environments, and shows up to three times the number of blooms as other varieties. Delta overwinters well and stays attractive during severe weather due to short, sturdy stems. Delta Premium varieties represent the most uniform, most manageable and most stretch-resistant colors in the series. Both early flowering and free-flowering characteristics remain the same in the Delta Premiums. Delta Premiums also offer a tight bloom window.
