Please Note: Some of the topsets are starting to sprout. These will take root quickly as they are coming out of dormancy. You will receive 20 organically grown Catawissa Egyptian Walking Onion topsets from my garden in Maine These bulblets will be of assorted sizes. The sizes are medium to large. Instead of flowers, this plant produces topsets, a cluster of bulblets, at the top of the stalk where the flowers and seeds would normally be. The stalks eventually flop over from the weight of the bulblets (if not harvested) and replant themselves, thus beginning their ?walk? across the ground. Also called tree onions or topset onions, this vigorous and trouble-free plant is hardy in zones 3-10. Plant them no more than an inch deep and 5-6 inches apart. For a small investment over time you will have onions for years and years to come. We've been harvesting our onions for 47 years. Thank you.....
