Passiflora Caerulea

Passiflora caerulea or blue passionflower is a climbing plant of the Passifloraceae family, native to South America. It is the most cultivated ornamental passionflower in countries with a temperate climate.

There are several cultivated varieties1 of Passiflora caerulea:

  • Constance Eliot is resistant to frosts of -15°C, very floriferous and very fragrant
  • China Blue has a light blue crown
  • Clear sky is a tetraploid cultivar

Many species of the genus Passiflora can hybridize with each other. From the beginning of the 19th century, the first successful cross was that of Passiflora caerulea and P. racemosa to give P. × violacea. Similarly Passiflora × belotti comes from the crossing of P. alata and P. caerulea. It can lose its leaves during vigorous winters (-10°C) which will grow back in the spring.
