I've been growing this variety for a little over 50 years. While unique, it's not a Red Emerald.

With the red leaf petioles, it definitely looks like a variety of Blushing Philodendron (Philodendron erubescens). Although I've never grown the cultivar 'Red Emerald' and I know that Philodendrons can be quite variable, tabbycat/Trudy's plant does look quite similar to many online photos of the cultivar 'Red Emerald'.

@Rustynickle, Other than the fact that you've been growing this particular cultivar for more than 50 years, can you offer any other information about why you feel that this database photo isn't the cultivar 'Red Emerald'? Your photo shows a juvenile plant even more immature than the one Trudy added to the database. Can you share a photo of a more mature plant and possibly point out the differences compared to this image? Additional information might help Trudy determine whether her plant was mislabeled when she acquired it and if it's in the incorrect database location, she can propose it be moved to the P. erubescens entry.

@Gina1960, I know that you are extremely knowledgeable about many plants in the Araceae family, can you offer an opinion on tabbycat's photo?

@Gina1960 I deleted your "I agree, not Red Emerald" comment because you added it to the database plant entry in the comments field rather than here in this thread.

I often cannot add things to the right place when I'm using my phone lol. No, that is not Red Emerald. I can post a photo of Red Emerald if you like

Gina, thanks so much for taking a look and confirming Rustynickel's observation. You should upload a photo of your Red Emerald to the database entry here: Philodendron (Philodendron erubescens 'Red Emerald')

@Calif_Sue, member tabbycat's last post was in May; perhaps her photo should be moved over to the main plant entry for all Philodendron?

I will add it tomorrow. I don't seem to have a photo of the plain form, Red Emerald. The variegated form is, of course, Strawberry Shake, seen here

Gina, Wow, that is really beautiful!

Yes its hard to believe the variegated form of Red Emerald is so much prettier than the normal form LOL

If 'Red Emerald' is a cultivar, can there be various forms of it?

Moved to generic entry

I am pretty sure the original photo posted by Tabby is Philodendron Red Emerald, an old old McColley hybrid

Well now I'm confused, you said no it isn't now you are saying yes it is?

OOPs I meant Red QUEEN sorry.
There is a Red Emerald, a Red Queen, a Red Empress.
Mine is Red Emerald. Hers is probably Red Queen
