Like all passionflower vines in Central Texas, bracted passion-flower attracts butterflies that lay eggs. The resultant caterpillars are voracious and may totally defoliate the vine,
but if bracted passionflower is well-established, the vine
will resprout quickly. Specifically the Zebra Longwing butterfly and the Gulf Fritillary use it for larval food. The flowers are intricate but not showy.
