For the best in spring-planted bulbs, visit the Michigan Bulb website. We offer a wide range of varieties that reliably grow and bloom in spring, summer or even fall. Plant bulbs in spring to enjoy rich color, unique textures and loads of visual interest to the landscape in the warm weeks of summer and into the cooler days of autumn. Spring-planted perennials will begin growing and thriving as soon as they are put in the ground, blooming at differing times throughout the coming season. We like planting several cultivars together in a blend of colors, heights and forms to create a garden display like no other.
