See, I learn something new here. I thought that pothos was just a nick name for philodendron. Like I used Sans for Sansevieria. I know there are dozens of heart shaped vines out there. I use a nursery like Hirts Greenhouses for ID. They have nice pictures to help. After I know a name then I turn to Daves Garden site to further explore it. My memory is fast failing me also. I use pictures of plants I buy and label them using the Paint program on Windows. After words I install them into a excel spread sheet and type in all the information I can remember. After about a year or so, I retake pictures and see how much they changed. I have a large list on Photo bucket which I kept free to the public to see or use as they want. Photobucket doesn't work on this site but you don't need it. I can easily download any picture off my computer's windows program to this site.
