● Additional Notes


This species is sometimes confused with Passiflora trifasciata, but it can be distinguished by its narrower lobes and faster growth. Its ornamental foliage is the primary attraction, with variegation intensifying under stable, bright conditions. While related passionflowers are sometimes grown outdoors in frost-free regions, this species is best kept as a collector’s plant indoors in Europe.
 
● Etymology of Passiflora tricuspis


The genus name Passiflora was created by Carl Linnaeus in 1753, from Latin passio (“passion”) + flora (“flower”), referencing the symbolic interpretation of floral structures by early missionaries. The species epithet tricuspis comes from Latin, meaning “three-pointed” or “three-lobed,” describing the characteristic shape of its leaves.
