Perennials have a longer lifespan than annuals and may bloom for several weeks or months each year. Lavender, jasmine, wisteria, peonies, and ornamental grasses are popular perennial choices for gardens, providing consistent beauty year after year. Practically, the best times to plant perennials are spring or fall. These seasons allow plants to get settled and grow new roots before summer’s hot, dry weather arrives. Planting in summer is okay, but you’ll need to water frequently.
