Here’s a quickie reminder of the differences between flower seeds, which are categorized as annuals, biennials, or perennials, depending on how they complete their life cycle.
An annual completes its entire life cycle in one growing season. Plant a marigold in the spring, it blooms in the summer and dies in the fall.
A biennial spends its first growing season becoming established and storing energy. It blooms during the second growing season. Hollyhock is a biennial.
Perennials continue to grow year after without being replanted. The usually go dormant over winter, and grow back from their roots each spring. Daylily is a perennial.
Some plants are actually annuals but people think they are perennial because they self-seed. The plants drop seeds as they die, and new plants grow from these seeds in spring. Cosmos is an example of a self-seeding annual.
