Features: This native wildflower will bloom July to September with fantastic blooms of white and purple crowns. It can be woody in warmer winters or will turn herbaceous if temperatures get low enough. Maypops appear in July, and ripen in early fall. Maypops are popular among wildlife and humans and can be eaten directly off the vine.¹²

Siting: Passion vine prefers well drained soiled with medium moisture. The roots like a loose mulch much of the time. Full sun is optimal for these plants, but part shade is tolerated.¹²

Care: Plant crown at soil level^18 and water the roots and surrounding area slowly and deeply. Keep soil moist until plant is established, then apply enough water to thoroughly moisten the root zone when the soil is dry or during drought. Modify water recommendations to reflect site drainage and rainfall. Apply 3” of mulch over the planted area. Do not allow mulch to touch the plant stems.¹⁸

Pests: Plants are relatively pest resistant if cultural preferences are met.
