Plants with a moderate growth rate are best planted in the spring after the risk of frost has passed. Perennial varieties will begin to bloom the second or third year after planting, while annual varieties will start to bloom early in the summer. Perennial varieties are more difficult to grow than annuals, but they can be grown year-round in most climates.
Perennials can also be propagated from seed or cuttings. The best time to plant perennials is in late summer or early fall when temperatures are warm enough for seed germination and the plants are ready to be transplanted into the garden.
