When planting your spring blooming bulbs this fall, consider adding some Fall Glade Onions to the mix. Fall Glade Onions, also commonly called Prairie Onions, add drama to your fall garden, just as other summer blooms are starting to fade. Fall Glade Onions grow easily in shallow, rocky soil in full sun to partial shade conditions. They tolerate the brutal conditions of extreme heat and dryness. Their pinkish-purple blooms appear in July, continue into September and then form attractive fall fruit. Plants typically reach 1 to 2 feet in height and spread up to 1 foot in width. All parts of the plant give off a slight onion scent when crushed. Fall Glade Onions are deer resistant.
