Do you get confused by the terms annual and perennial? An annual is a plant that lives for one season and is sensitive to frost in our area. It is usually safe to plant annuals around Mother’s Day or after, as mid-May is the average “frost-free” time. A perennial is a plant that comes back year after year. They are usually outdoors or ‘hardened off’ when you buy them and can typically be planted or moved in April. If you purchased a perennial from the greenhouse, you will want to harden it off before planting it.
