Heart-Leaf Philodendron - Sweetheart Vine
First a warning: all these short films here are for artistic purposes, e.g. to capture a still image for painting, drawing, and who knows to study the patterns of its leaves, but never to teach about its cultivation or maintenance.
This sort of Philodendron have several names considered as formal or scientific denominations, such as Philodendron Cordatum and Heart-Leaf Philodendron; and as all sort of a species in particular, this have too a myriad of variation in its size, shape, and color. I hope that you could find the exact frame for your work.
