Philodendron giganteum

Philodendron giganteum

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.

Description:

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.
