Passion Flowers are native to Brazil and Argentina and are an absolute must-have for any romance, heirloom, or butterfly garden.All passion vine flowers are unique and unlike any other flowering plant. In the early 1600s, Catholic priests in Peru documented what they believed to be a religious symbolism in the unique flowers of this beautiful vine. The priests related the parts of the flower to features of the Crucifixion, and thus the name passiflora or passion flower was coined. Ruby Glow is a tropical species of Passiflora that is a fast, vigorous grower. It quickly establishes into a dense, lush vine that typically begins flowering when young and requires only basic care to thrive. Flowers are an exceptionally large and beautiful version of the unique to the species bloom in a deep purple-toned maroon-red with sharply contrasted, long violet-blue and white filaments. It can produce fruit but requires pollination by another type of passion vine. Care: For optimal growth, plant your passion flower in a partial-shade location with fertile, well-draining soil and a trellis or other support. Water deeply, allowing the soil to dry out slightly between waterings to avoid spindly growth. Fertilize with a quality, bloom-boosting fertilizer in the spring, and prune as needed after flowering to control size. Indoor Growing: While most Passion Vines can be grown indoors, Ruby Glow is not generally a suitable choice for average indoor growing spaces. Substantial modifications to increase light, temperature and humidity are necessary. Climate: This vine is suited for tropical climates, and is recommended for Zones 9B, 10, and 11.
