Tiger on Azaleas, March, 2013
These are not the decorative Pipevines known as Dutchmen's Pipe.
These are native pipevine Aristolochia tomentosa (Wooly pipevine). This small downier version of A. macrophylla occurs from North Carolina and Missouri south to the Florida Panhandle and Texas. The flowers are very small and insignificant unlike the big Dutchmen's Pipes usually seen as Pipevine.
These are immature vines. Mature vines reach high up the tree.

These are the butterflies we hope to see in great numbers soon. Duranta flowers are yet to appear.
