Philodendron squamiferum
 
Common Names Hairy Philodendron, Red-Stem Philodendron
 
Zones 10A–11 (outdoors); Zone 9+ with protection; indoor year-round in colder zones
 
Philodendron squamiferum is a striking epiphytic aroid native to the tropical rainforests of French Guiana, Suriname, and northern Brazil. It’s best known for its fuzzy red petioles (covered in soft pubescence) and deeply lobed, oak-like leaves. A vigorous climber, it thrives when given vertical support and high humidity, making it ideal for tropical interiorscapes or greenhouse collections.
