My Giant Phildendron

The parent plant was a wedding present to my parents about 35 years ago and I took an offshoot a couple years ago. Now in a pole position along the main windows, it gets plenty of light to thrive...and boy is it thriving! Every new leaf seems to be just a bit larger than the last. Then this monster came out last week and it's a monster! I made sure to include my hand as a reference. The bottom is cut off but runs to my wrist , making this leaf about 4 hand-lengths. Man I love this plant!
