How to Grow

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.
