Philodendron grandipes K.Krause

• Genus: Philodendron
• Botanical Background: Discovered by botanist K. Krause, the species was described in the early 20th century. It was later recognized for its ornamental and ecological value. There is limited historical reference, but Krause's work in the genus helped to highlight its diverse members.

• Geographical Range: Indigenous to lowland rainforests and humid tropical regions of Central and South America, including parts of Panama, Colombia, and northern Ecuador.
• Environment: Thrives in humid, warm climates with temperatures ranging from 24°C to 30°C. It is found at lower altitudes, where rainfall is frequent and the environment is rich in organic matter. The plant favors well-draining, slightly acidic soils.

Leaves

• Large, heart-shaped, and leathery
• Glossy dark green coloration
• Can grow up to 1.5 meters (5 feet) long
• Margins are often slightly undulating

Inflorescence (Spadix & Spathe)

• Consists of a typical Aroid spadix surrounded by a spathe, which is pale green or white in color
• With a faint scent

Growth Habit

• An epiphytic plant
• Spreads via a creeping rhizome that can produce aerial roots

Light Requirements

• Bright, indirect light
• Can tolerate some direct sunlight in the morning or late afternoon

Watering & Humidity

• Regular watering is essential
• Keep the soil evenly moist but not soggy
• High humidity (60-80%)

Soil & Potting Mix

• A well-draining potting mix rich in organic matter
• With a mix of peat, perlite, and bark

Temperature & Fertilizer

• Temperatures between 24°C and 30°C
• Monthly fertilization during the growing season
• A balanced, water-soluble fertilizer

Division and Stem Cuttings

• Stem cuttings that include at least one node
•  Can be rooted in water or a moist potting mix

Seeds

• Possible if viable seeds are available. Germination requires warm temperatures and consistent moisture

Typical Issues

• Aphids, spider mites, and mealybugs
• Root rot

Treatment Recommendations

• Insecticidal soap or neem oil
• Improve drainage
• Adjust watering schedule

• Large leaves are a distinctive feature
• Often compared to those of some of the largest species in the Philodendron genus

• Dramatic, oversized leaves, making it a showstopper in both indoor and outdoor tropical gardens

Wild Population Status

• Does not appear to be under significant threat
• Habitat loss due to deforestation poses a general risk to tropical plant species

Market Availability

• Not widely available in all regions
• Can be found in specialty nurseries or through plant enthusiasts’ networks
