Four OâClocks are only hardy in USDA zones 7-10. In zones 7 and 8, mulch heavily in the fall for added winter protection. In colder zones, treat the plants as annuals or dig up the tubers and store for next year. Dig after the first light fall frost and store in barely damp vermiculite, peat moss or sand in a cool, dry place (40-50Â°F). Four OâClocks may also self seed, even in colder climates.
