Description:

Philodendron holtonianum is a rare and exotic aroid prized for its long, narrow, deeply lobed leaves that resemble graceful green fingers. Native to tropical Colombia, this climber showcases a dramatic and elegant silhouette as it matures, making it a standout in any rare plant collection.

With its slender, strap-like leaf shape and strong climbing growth habit, holtonianum is perfect for vertical displays. It appreciates bright, indirect light and high humidity—conditions that help it produce increasingly large and beautifully lobed foliage over time.

Care Tips:

• Provide a moss pole or trellis for vertical growth and proper leaf development.

• Maintain high humidity (ideally 60–80%) for optimal growth.

• Keep in a warm environment and avoid cold drafts.

• Water moderately—do not let the plant sit in soggy soil.

• Fertilize monthly during the growing season with a balanced, diluted fertilizer.

Growth Habit:

• Upright climbing aroid with long, lobed leaves.

• Juvenile leaves are narrower and become more deeply divided with age.

• A dramatic and architectural plant for aroids collectors and enthusiasts.

Pet Safety:

Toxic to pets and humans if ingested (contains calcium oxalate crystals). Keep out of reach of pets and children.
