I live in Michigan and experience all 4 seasons. I have a seasonal outdoor garden in my backyard and a year round indoor garden. I grow annual flowers, vegetables, herbs, and butterfly host plants outdoors in the spring, summer, and fall. I grow annual flowers including impatiens, vinca, and begonias indoors under grow lights all year long. My favorite gardening season is late spring because the weather is perfect and that is when nurseries have a wide selection of plants available.
