PlantFiles: Blue Passion Flower, Hardy Passionflower
Passiflora caerulea 'Constance Elliott'

This is a very cold hardy variety - has survived snow, ice and long low sustained freezing temps teens and 20's for several days with no freeze damage to limbs. Unlike my other passion vines which fade at the first hard frost or before. Agree on trimming back in late fall or Feb-Mar to promote flowers on new growth. Lots of white flowers, little to no fragrance, unlike the incensa variety.

Does spread via underground roots into other areas easily. Suggest placing on its own fence away from your permanent beds. I routinely pull new sprouts in my beds 10-15 feet from base.

I planted one of these on a west-facing fence in the spring of 2003 in Dallas, TX. The plant endured a freakishly heavy snow in the winter of 2004 and has not only survived, but flourished and now covers over 50% of a 32 ft long fence. it has produced absolutely tons of flowers and to my surprise, it has started to produce fruit. i planted a cerulean this year and next year I hope to have a fence entirely covered in the white and blue flowers.

I have never seen this one. Does it produce fruit?

I have Constance in my garden for four years now growing on a southfacing wall near to my terrace. Every year it gives me countless flowers which are lovely perfumed too. The flowers grow on first year branches..so in spring I give her a good trim. She appeared hardy enough for me and has survived a harsh winter 2002/2003 with temps down to - 18 C
Well..I don't know any other flower that sticks so nicely on my pics...it has such a very interesting shape.
