Black Cardinal is best grown in well-drained, moist soil in part shade. Too much light or too little moisture can cause the leaves to become pale and brown. Philodendrons also do not like overly wet or cold soils. Avoid alkaline soil.

Black Cardinal philodendron is a fantastic understory plant in shady gardens in warm, frost-free regions. It is also an excellent houseplant in bright, warm indoor spaces.

The philodendron leaves and stems are poisonous, and the juices can cause skin irritation in some people.
