Philodendron bernardopazii (Clone1) (superbum) was known, for a long time as a form of Santa Leopoldina. The name Philo superbum was later given to it until the official name benardopazii was finally the proper species name. I have been collecting clones of Philo benardopazii for many years. As far as I can tell their are at least 5 known clones in the trade. This clone being one of the more common and easier to find it is still a very beautiful plant and very well worth growing. The leaves when young or in hot dry areas tend to become very long and narrow. In more shade with more watering the leaves can get wider and more hastate to almost triangular in shape. I will show some pictures of the plant in both conditions. Thought they may look very different they are the same species. Each leaf has a sheen and white veins. The petioles are rough and with ridges down them and dark sap glands to attract ants to help ward off potentially bad insects. One of the more ornamental species it is a great plant and easy to grow. Just plant in a container and give it a totem to climb.
Photos of plant with white back ground are of the plant up for auction.
