Gardeners' Notes:

This seems to be somewhat of a passalong plant here in Texas. It's a passionflower vine, cold-hardy in my area, the above-ground parts dying back in winter and it starts growing again in spring. It's a host plant for the Gulf Fritillary butterfly. I have it on fences, but like many p-vines, it will eventually come up elsewhere than where the original plant was, sending out underground runners. The flowers on mine are light pinkish to lavender, the leaves and stems are hairy, it forms "fruit" which can turn red and flowers/fruits have these lacy bracts. The odor of the plant is most noticeable by the bracts. Many people say the odor is unpleasant but I don't think it's so bad at all.
