Philodendron giganteum or giant philodendron is a vine with huge leaves.
Although it may be grown in pot as a houseplant, it will not grow as strongly outside a tropical climate.
It is not rustic but may be placed outdoors in the summer.
Philodendron giganteum is usually epiphytic, sometimes terrestrial.
It is a climber with stems up to 2 m long and up to 8 m long roots.
The leaves are usually 25-60 cm long and 17-50 cm wide but leaves of almost 2 m long have been observed.
The petiole is at least as long as the leaf blade. The nodes are very close to each other.
The flowers are very beautiful, arum-like with a white spadix, but the plant blooms rarely in colder climates.
