    Why the Medusa Ornamental Onion?

    This isn't the Greek monster Medusa, but the ornamental onion that has twisty leaves like the feared Medusa's hair. Don't let this allium scare you, it's only around to provide purple bloom clusters to your landscape. Great for bees and butterflies, Medusa will only bring in the visitors you want, and is resistant to pests such as deer. A distinctive plant in your landscape, Medusa will excite and not frighten!

    Onions belong to a genus (Allium) that includes familiar edibles like garlic, chives, shallots, and so much more. There are around 850 species of Alliums globally, nearly all of them native to the Northern Hemisphere. Many have in typical musky-smelling foliage and uniquely arranged flower heads that form globes or starburst patterns. Millenium was bred in 2000 (hence the name) by Mark “The Onion Man” McDonough of Pepperell, Massachusetts. McDonough is an architect by trade and an amateur gardener on the side with a passion for ornamental onions. Millenium is one of his finest introductions.

    How to use in the landscape?

    No need to be frightened, Medusa Ornamental Onion is here to please, not harm! Medusa is a fast-growing perennial that sends up round balls of purple blooms that are long-lasting and perfect for a tabletop bouquet! Alliums are great drought-tolerant plants that have shown to be long-living.

    How To Plant

    Plant Medusa Ornamental Onion in a site in the all-day sun; afternoon shade may be a good idea in very hot climates. Medusa grows best in light (sandy), free-draining soils. It has average to low water needs, withstanding periods of drought once established. Most border situations suit it well, and it is at home in the rock garden, too. To use the flowers in arrangements, cut them as soon as they open, and they’ll last a long time in the water. Diseases and insect pests are rarely a problem with this carefree Spirit; deer and rabbits avoid the aromatic foliage as well.

    How To Water

    Water twice weekly for the first 3-5 weeks; then water weekly for the remainder of the year until winter. When you water, water slowly and thoroughly. Watering needs may be altered due to extreme weather conditions.

    How To Fertilize

    Incorporate Elements Starter Plant food granular form into the soil when planting. If planting in spring or summer, start fertilizing late fall using Elements Starter Plant food granular form on an annual basis each late fall. Continue this for the first three years to get your plant well established.

    How To Prune

    Each fall, just before winter sets in clean up the previous years foliage and compost it. Be sure your perennials are mulched well for winter protection. Two inches of an organic mulch will do the job. Consider leaving the plant debris in place through the winter and doing your clean up on the weather warms in the spring. While it doesn't make things neat and tidy, the debris provides overwintering protection for insects, their eggs and pupae including our native Viceroy butterfly.
