Trumpet Creeper, Campis radicans, is a native vine capable of taking over a landscape through both growth and prolific seedlings. Vines with diameters over six inches climbing into trees are not uncommon while the related crossvine, Bignonia capreolata, may be little over an inch across in the same period of time. The flowers are orange with cultivars that range from yellow to red and bloom during the summer, which is idea for hummingbirds, thus it is often markeded as a hummingbird vine. Some additional caution should be taken considering the alternate common name of cow-itch vine, because some people are as sensitive to it as poison ivy, Toxicodendron radicans, and this may even include drinking the fresh milk from cows that ate it.
