Hi!
I would very much appreciate help identifying this philodendron (?).
I have probably been through 120+ varieties online, some look pretty close but none have the same specific leaf/color/vine/root combination.

It looks like a variety of Philodendron erubescens to me but there are so many hybrids out there that I don't know how to tell one from another sometimes. Hopefully someone more familiar with Philodendron will be able to help but meanwhile, we have several listed in our database, many with photos for comparison; you can access the entries here: https://garden.org/plants/sear...

Looks like Imperial Red to me. Its a climber, for sure. I am really bad at IDing these old varieties. I can ID Rojo Congo, but I was never really enamored of the others in the 'Royal Court' of the McColley hybrids, and never collected them. Keep in mind there are a lot of hybrids coming out too. Might be harder to ID something that really has no definitive unique identifiers, like this one, and like THIS green one I have been trying to ID for 15+ years

This might give you a hint as to how hard it can be to ID some of these plants.
This is what are known as the 'Royal Court' or 'Royal Flush' Philodendrons. You will note that most have more than one name, which only adds to the confusion surrounding them.
Many are McColley Hybrids, but not all, some are BELIEVED to be from the McColley breeding program, but its uncertain as he made so many thousands of plants, most of which he never patented and Brough to market, but still probably float around, being originally in the collections of a few old collectors then shared through gifting and trading until eventually a lot of people may have them but no one is sure what they are. Perhaps you may see your plant in one of my photos

1. Ace/King of Spades...known ONLY in Australia as Anderson's Red, known here and most often as King of Spades, and is believed to be the same plant as Dark Lord. This is mine


2. Red King (may or may not be the same as Sun Red/Red Sun)
3. Royal Queen (aka Zulu Prince, Black Knight, Black Jack, Bloody Mary, Majesty)
I purchased mine prior to 2010 from Asiatica Nursery as Zulu Prince

4. Queen Elizabeth...believed to have originated in India, then was exported to Australia. Its very rare in the US, I happen to have one

5. Prince of Orange

6. Prince Albert
7. Pink Princess

8. Orange Princess
9. Green/Burgundy Princess (a reverted Pink Princess, to either green or burgundy)

10. White Princess
11. Emerald Duke
12. White Knight
13. White Wizard

14.Imperial Green
15. Imperial Red
16.Red Empress (a form of Henderson's Pride that flushes red under light stress)
17 Choco Empress (aka Green Empress, Caramel Express, Pluto)
18. Painted Lady

Wow thanks everyone!
I guess I'll have to live with the mystery.
To add to the story, one may have or may have not pirated a cutting from a science museum greenhouse.. could be something interesting indeed

Wow, this one is suspiciously similar! Haha

Yes, just green. It gets really huge too. his was a few years ago, the leaves are about 2 ft long now
