Passiflora caerulea is cultivated widely in the flora area but naturalized only in the Los Angeles metropolitan area (see F. Hrusa et al. 2002). It is possibly introduced in the Mule Mountains of southeastern Arizona (J. Koweek, pers. comm.), although this has not been confirmed. It was reported also from Utah by S. L. Welsh et al. (2003), although as “cultivated...long-persisting,” suggesting that it is not actually naturalized there. This species is cold-hardy and can be cultivated in gardens in relatively cold regions (at least USDA plant hardiness zone 6), but it is unlikely to flower in such areas because of relatively short growing seasons, although it still makes an interesting foliage plant. Even in the absence of sexual reproduction, this species can persist and even spread locally by root suckering. The artificial hybrid Passiflora ×belotii will key to P. caerulea in this treatment. However, the leaves of P. ×belotii are consistently three-lobed, unlike the primarily five- to seven-lobed leaves of P. caerulea.
