The Bluecrown Passionflower is a vining herbaceous perennial that is native to parts of South America, and it is the national flower of Paraguay. It may grow from 10 feet to over 40 feet tall. It has showy blue and white flowers and orange fruits. It is a member of the Passifloraceae family. The genus name of Passiflora relates to the crucifixion of Jesus Christ. In the 15th to 16th century, Roman Catholic priests named the plant for the Passion of Christ or suffering and death of Jesus Christ. The species name, caerulea, refers to the blue colored filaments of the flower.
The unusual saucer-shaped flowers on long stems typically appear from early summer to early fall. The fruits appear late summer through the fall and are green ripening to yellow and deep orange. The fruit is partly hollow with a small amount of deep red colored pulp surrounded by a large amount of seeds. It is evergreen in warm winter climates and deciduous in temperate climates.
The showy ornamental Bluecrown Passionflower is a good choice for arbors, containers, cottage gardens, trellises, walls, and fences. The tendrils cling to brickwork, arbors or fences, but it will not cause any damage to their surfaces. They like high humidity, but they may develop fungal diseases if the air is not well circulated. The roots may also develop fungal diseases if an excessive amount of top growth is removed all at once. Butterfly caterpillars may eat the foliage of mature plants. Bees and butterflies are attracted to this beautiful flower.
The plant may be propagated by cuttings or seeds. The plant may be pruned after it has bloomed to reduce the size of the plant. You may cut back the year's growth by one-half. Deadheading of flowers should be done regularly.
