The Philodendron Black Cardinal is a very unique Philodendron. Known for its thick leathery and nearly black leaves that transition into a dark green leaf with red and black hues, it can be quite the conversation starter. They are a very easy-going Philodendron that doesn’t need the bright light that most others need. It is also a great option for those who are new to houseplants, as it can withstand a variety of conditions and can also take some neglect here and there. If you have gotten a Black Cardinal or are thinking about getting one this guide has everything you need to know about Philodendron Black Cardinal care.
The Philodendron Black Cardinal was released, along with other newly discovered Philodendrons like the Philodendron Prince of Orange, from R.H. McColley’s breeding program in Apopka, FL. Patent USPP5355P was filed in 1983 by Cora McColley for the Black Cardinal.
The Philodendron Black Cardinal was a result of a seed that was a cross between the Philodendron wendlandii, Philodendron hastatum, Philodendron erubescens, Philodendron imbe, Philodendron fragrantissimum, and another Philodendron that is unambed.
The Black Cardinal had some similarities to another patented Philodendron, the Philodendron Royal Queen, but there were some distinct differences that made it stand out. It has black leaves with red undertones and blackish red petioles and stems. As the leaves mature they lose much of the black and will go from red to a reddish black green color. The Philodendron Black Cardinal is also a self-heading plant, so it won’t need a pole to climb up and will stay more compact than some of the other climbing Philodendron erubescens varieties.
