Gardeners' Notes:


On Nov 6, 2015, coriaceous from ROSLINDALE, MA wrote:

This woody twining vine runs and spreads quickly underground. For most applications, like screening a porch, it's important to install root barriers to confine its spread---and that won't stop self-sowing. The woody stems do not die back to the ground in winter.

The flowers are interesting but not showy. They're small and mostly hidden beneath the foliage.

I purchased a pipe vine from a plant show. It wasn't blooming and it still isn't the leaves look simiar to this one and different from my other ones smaller and has a rougher/sandpaper like thicker texture...still waiting for it to bloom to give it a proper ID hoping since it has been in the ground now almost a year went dormant and came back great that it has a mind to bloom. I did notice though that I am finding under ground runners a distance from the original plant popping up...I hope this isn't a bad sign, because I am no stranger to a shovel!!

This is a great vine if you have a relatively large area that needs covered by some attractive green foliage. Mine has covered two sides of a very large deck (it has spread 40 feet wide and grown about 15-20 feet up to the top of the deck) It provides a 'cooling' effect on the deck during the summer to take the edge off the summer heat. Also, there are almost always Pipevine Swallowtail butterflies hovering around it gracefully which is another positive.... and its a native vine! There are only a few species of Dutchman's Pipe native to North America and this is one of them.

Could hoping make it so?... The vendor who sold me this Wooly Pipevine was mistaken~ He said it was A. macrophilla, but I had it sent anyway for want of a Pipevine Swallowtail host plant. Since it's bloomed I have been delighted to find that it was our native A. tomentosa all along!! The plant I originally wanted. Someone *up there* must have heard me hoping. :-)

Aristolochia is a larval plant for the pipe vine swallowtail butterfly, so it's a good choice for a butterfly garden if you have them in your area. According to the Missouri Botanical Gardens, which selected this cultivar as a Plant of Merit in 2004, it provides "dense cover for sun porches, verandas, pillars, posts, trellises, arbors, fences or walls. Has been popularly used for many years to screen front porches."
