Pests in Gardens and Landscapes

Petunia—Petunia x hybrida
Family Solanaceae (Nightshade family)

Plant Identification

Petunias are low-growing perennial plants generally treated as annuals. Leaves are thick and somewhat sticky. Flowers may be ruffled or funnel-shaped and are of various colors including white, yellow, red, blue, and purple. They bloom from spring into winter. Petunias are often grown in beds, containers, window boxes, or as ground covers.

Optimum conditions for growth

Petunias require regular water and fertilizer, and they must be planted in soil that drains well. Plants do well in areas with full sun. After the bloom period, remove old flowers to promote new plant growth.
