Passiflora vitifolia 'Scarlet Flame' (Red Granadilla) is a vigorous evergreen climber with reddish orange flowers, 4-5 in. wide (10-12 cm), adorned with a ring of bright red coronal filaments. ... Blooms from early summer to fall. Thrives in full sun in fertile, moist, well-drained soils.
Passionflower prefers moist – but not wet – soil with good drainage. Offer approximately one inch of water per week, or as often as necessary to keep soil from drying out.
As mentioned previously, mature plants do not always respond well to transplanting, and you may notice some wilting or die off of vegetation at first. Applying some aged manure, compost, or fertilizer may help to perk the plant up until the roots are reestablished.
Even though the vines do not require pruning to produce flowers and fruit, they can quickly become overgrown in the home garden under ideal conditions.
The Passionflower vine prefers a frost-free climate. Some cultivars can take temperatures into the upper 20° degrees Fahrenheit without serious damage.
This tropical species of the passion flower family is the most poisonous plant in the world, according to the University of Berkeley. Its tuberous roots include a deadly mix of cyanide and a slower-acting poison unique to this plant. Passiflora coccinea (common names scarlet passion flower, red passion flower) is a fast-growing vine. The vine is native to northern South America. It produces edible fruit. Most plants cultivated as Passiflora coccinea turn out to be Passiflora miniata Vanderpl.
