Passiflora quercetorum is a small, erect to weakly climbing or occasionally procumbent herbaceous perennial plant producing a clump of annual stems around 30 - 90cm tall[
The plant is harvested from the wild for local use as a food and a medicine.
Southern N. America (northern Mexico (Sonora and Chihuahua)
Dry oak forest, lower pine forest and the transitional contact zone[
]. Humus-rich soils among rocks on canyon slopes; at elevations from 1,050 - 1,500 metres[
Passiflora quercetorum is native to the semi-arid, subtropical climate of northwestern Mexico, where it is found at elevations up to 1,800 metres.
Passiflora species generally grow best in a sheltered, sunny position or in dappled shade. Most species are found in the wild in moist but well-drained soils, generally of a lighter texture, and will often flower and fruit more heavily if the soil fertility is low. They often develop deep roots and can be moderately tolerant of dry spells. Most Passiflora species prefer a neutral to slightly alkaline soil, growing best where the pH is around 6. 5 - 7.5[
Fruit - raw[
]. The pulp surrounding the seeds is eaten. A sweet flavour, the fruit is prized as a treat by children[
]/The light yellowish green, widely ovoid fruit is around 35 - 40mm long (including a 4 - 5mm long stipe), and around 25 - 30mm in diameter[
]. The pale yellowish, gelatinous arils are much longer than the seed[
A tea made from the plant is used in the treatment of cough[
The leaves and roots of some, if not all, members of this genus contain a substance called 'passiflorina' which has similaritiesr to morphine and is an effective tranquilizer[
]. We have no specific information for this species but many species are used in herbal infusions to calm the nerves and help bring about a restful sleep[
The leaves of many species are also considered to be anthelmintic, antihysteric and diaphoretic. They are used in Brazil to combat intermittent fevers, cutaneous inflammations, and erysipelas[
Pre-soak the seed for 12 hours in warm water and then sow late winter or early spring in a warm greenhouse. If sown in January and grown on fast it can flower and fruit in its first year[
]. The seed germinates in 1 - 12 months at 20°c. Prick out the seedlings into individual pots when they are large enough to handle. It you are intending to grow the plants outdoors, it is probably best to keep them in the greenhouse for their first winter and plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Mulch the roots well in late autumn to protect them from the cold.
