These deep burgundy ranunculus bulbs make an unforgettable statement in vases, wedding bouquets, and boutonnieres. They grow to about 1 foot tall with delicate layers of paper-thin petals reminiscent of soft chiffon. They make an incredible focal point in flower beds—just make sure they're placed in sunny spots because they require full sun. When it's bloom time, you'll be so delighted with the romantic, almost gothic, results produced by our Black Ranunculus Bulbs.

Note: In Zones 8–10, ranunculus are grown as perennials—plant in fall for spring blooms. In Zones 4–7, they are treated as cool-season annuals. Start corms indoors in late winter and transplant after nights stay above 30°F, or dry-store them and plant in spring after hard frosts.

    Ranunculus Bulbs - Black

    I planted all 30 of my ranuncula bulbs according to the instructions. Unfortunately, not a single one came up. I don't know if it's because of all the rain, or what. But, I'm so sad and disappointed because I really wanted them to thrive.

    Customer service and shipping are fine, but I ordered several ranunculus from Eden and they are not 5 to 7cm, maybe 2 to 3cm at best, they are VERY small. Disappointed
