Passiflora caeruleaWhats in a name?

( Pass-siff-FLOR-ruh kah-eh-ru-LEH-a or see-ROO-lee-uh depending on how latin you want to be I guess??? the internet seems to give both pronunciations by seemingly educated sources so I remain lost on how to correctly say this name! ) Passiflora means ‘passion flower’ and caerulea means ‘quara’ and refers to the bright blue color of the filaments on this flower. Not that that will ever get anywhere, sometimes its just fun to see the breakdown 🙂

The blue passion flower will forever have a place in my heart simply because after being planted into my home garden it attracted my first zebra longwings to my garden. I LOVE it when a new species shows up! I think it had more to do with the fact that it attached itself to a nearby magnolia and climbed up it in the shade but it still gets all the credit to my mind. Blue caerulea vines are utilized by zebra longwings, gulf Frittilary and Julia butterflies as larval host plants for their caterpillar babies so you will often see them fluttering about laying eggs on the leaves.

Passionflower vines are short lived perennials that you can expect to live a few seasons in the landscape.
