Plant Common Name
Very cold tolerant, fragrant, and beautiful, passion flower ‘Incense’ is a popular perennial vine. It is a hybrid between the United States native Passiflora incarnata and Passiflora cincinnata from South America. It is evergreen in frost-free areas and deciduous in colder locations.
The dark green, lobed leaves are arranged alternately on thin stems. The vines climb by tendrils produced in the leaf axils (joint between the leaves and stems). Beautiful, spicy-sweet scented, lavender-purple flowers appear summer through fall. The complex flowers are composed of creamy-green hued fleshy reproductive structures surrounded by a fringe of dark purple lavender filaments and many lavender petals. Edible, egg-shaped passion fruits follow the flowers from late summer into fall and are yellow to olive-toned when ripe.
Passion flower ‘Incense’ is a large, vigorous, aggressive vine and soon covers structures or other plants. It prefers to grow in full sun but will tolerate light shade for a short portion of the day. Well-drained soil is required. Passion flower vines are drought tolerant but look best with irrigation in dry times. This hybrid is has some tolerance for heat and cold. It will take a few degrees around freezing and is root hardy if well mulched. Grow it in containers where not hardy.
Passion flower vines can be weedy, spreading by suckers and rooted stems. In some areas it is considered an invasive plant. It is the host and larval food for several butterfly species which can cause the leaves to look tattered and chewed. Grow “Incense’ as a ground cover, or on trellises and other supports, for the lovely flowers and abundance of butterflies it attracts.
