When the last threat of frost has passed and the soil warms, "Petunia Season" officially begins. Typically running from late spring (mid-May in northern zones) straight through to the first hard frost of autumn (October or November), this is a marathon of floral performance. Whether cascading from a hanging basket, filling a border, or spilling over a stone wall, petunias define the look of a cheerful, thriving summer garden. Rating: ⭐⭐⭐⭐ (4
