Passiflora jorullensis – Mexican Passionflower with Compass-Shaped Leaves


Passiflora jorullensis Kunth  is a rare climbing species from Mexico, remarkable for its unusually sculpted foliage. The large, bilobed leaves appear as if drawn with a compass: broad semicircles intersect at the petiole, while the two rounded lobes and the shallow cleft between them form perfect arcs. This geometric precision gives the plant a distinctive architectural quality that makes it stand out among passionflowers.
 
● Characteristic Features of Passiflora jorullensis


Leaf Structure: Very large bilobed leaves with rounded lobes and shallow central incision.
Leaf Form: Geometric, arc-like curves that create a compass-drawn look.
Growth Habit: A vigorous climber requiring support such as trellises or poles.
Flowers: Small, modest passionflowers that complement the bold foliage.
 
● Origin and Habitat


First described by Karl Sigismund Kunth in 1817, Passiflora jorullensis is native to the volcanic landscapes of the Jorullo Mountains in central Mexico. It thrives in warm, humid habitats, often climbing through shrubs and trees at mid-elevations. Its adaptation to a montane environment makes it tolerant of temperature variations as long as frost is avoided.
 
● Care Recommendations for Passiflora jorullensis


Light: Prefers bright, indirect light; can handle soft morning or evening sun.
Watering: Keep soil evenly moist; avoid waterlogging by using a well-draining mix.
Humidity: Average indoor humidity is usually sufficient, though higher humidity supports vigorous growth.
Substrate: Rich, airy substrate combining organic matter with mineral drainage components.
Feeding: Apply balanced fertilizer during the growing season to sustain large leaf development.
Support: Provide a trellis or climbing frame for natural twining growth.
 
● Possible Cultivation Issues


Leaf Yellowing: May occur if roots stay waterlogged; ensure free-draining soil.
Slow Growth: Often linked to insufficient light or nutrients.
Pests: Susceptible to spider mites or aphids in drier indoor conditions.
 
● Additional Notes


This species is sought after more for its dramatic leaves than its flowers. The foliage provides a bold, architectural statement, making it a collector’s piece in greenhouses or indoor plant displays. Its unique geometry distinguishes it from most other passionflowers in cultivation.
 
● Etymology of Passiflora jorullensis


The genus name Passiflora was established by Carl Linnaeus in 1753, from Latin passio (“passion”) and flora (“flower”). The species epithet jorullensis designates its place of origin, the Jorullo Mountains of Mexico, reflecting its natural distribution.
