Paper Plant vs Penstemon Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Paper Plant
Tetrapanax papyrifer
Tetrapanax papyrifer, the Paper Plant, is a large, fast-growing shrub or small tree typically grown outdoors. It features enormous, deeply lobed palmate leaves that can reach up to 3 feet across, giving it a bold, tropical appearance. The plant produces clusters of small, creamy-white flowers in late autumn or early winter, followed by dark berries. It is primarily cultivated for its striking foliage and architectural form. While sometimes grown indoors, it requires very bright light and ample space to thrive, making it challenging for most indoor environments. The pith of the stems was historically used to make rice paper.
Penstemon
Penstemon spp.
Penstemon is a diverse genus of flowering plants, primarily herbaceous perennials, known for their vibrant, tubular flowers. They range in size from a few inches to several feet tall, with varying growth habits from upright to spreading. The flowers come in a wide array of colors, including shades of blue, purple, pink, red, and white, attracting pollinators like bees and hummingbirds. Penstemons are primarily grown outdoors in gardens and naturalized areas for their showy blooms, drought tolerance, and ability to attract wildlife. They are not typically grown indoors due to their high light requirements and need for specific environmental conditions.

💧 Watering Needs
Paper Plant
Water thoroughly when the top inch of soil is dry during the growing season. Reduce watering in winter. Overwatering can lead to root rot, especially indoors. Underwatering will cause leaves to droop and brown.
Penstemon
Water deeply when the top inch of soil is dry. Avoid overwatering, as Penstemons are susceptible to root rot. Allow the soil to dry out slightly between waterings. Signs of overwatering include yellowing leaves and wilting, while underwatering can cause leaf drop and stunted growth.

❓ Frequently Asked Questions — Comparing These Plants
Paper Plant
What are the light requirements for Paper Plant?
Paper Plant needs bright, indirect light to thrive. Insufficient light can lead to leggy growth and pale foliage. While it can tolerate some direct morning sun, avoid intense afternoon sun, which can scorch the leaves. A location near an east-facing window is ideal. If using artificial lighting, provide 12-14 hours of light per day with a full-spectrum grow light. Rotate the plant regularly to ensure even light exposure on all sides. If the plant is in a pond, ensure it receives adequate sunlight but is also partially shaded during the hottest part of the day.
How do I care for Paper Plant?
Paper Plant thrives in consistently moist to wet conditions. Ideally, keep the base of the plant submerged in water or in very wet soil. Provide bright, indirect light for optimal growth. Direct sunlight can scorch the leaves. Maintain a water temperature between 65-80°F (18-27°C). Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength, specific for aquatic plants. Prune regularly to remove any dead or yellowing foliage. Repot annually in spring to refresh the growing medium. Monitor for pests like aphids or spider mites, and treat promptly if detected. Ensure good water circulation to prevent algae growth and maintain water clarity.
How do I propagate Paper Plant?
Paper Plant can be easily propagated through division or cuttings.
Penstemon
What are the light requirements for Penstemon?
Penstemon requires at least six hours of direct sunlight per day to thrive and produce abundant blooms. A location with full sun exposure is ideal. If growing Penstemon indoors, place it near a sunny window, preferably a south-facing one. Insufficient light can result in leggy growth, reduced flowering, and pale foliage. In hot climates, some afternoon shade may be beneficial to prevent scorching. Rotate the plant regularly to ensure even light exposure on all sides. Consider using grow lights to supplement natural light during the darker months of the year, especially for indoor plants.
How do I care for Penstemon?
Penstemon thrives in well-draining soil and prefers full sun, although some varieties can tolerate partial shade. Water regularly during the first growing season to establish a strong root system, then reduce watering frequency as the plant matures. Avoid overwatering, as this can lead to root rot. Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant blooms. Deadhead spent flowers to encourage continuous blooming. Prune back in late fall or early spring to maintain shape and remove any dead or damaged growth. Provide good air circulation to prevent fungal diseases. Mulch around the base of the plant to conserve moisture and suppress weeds. Penstemon is generally hardy but may benefit from winter protection in colder climates.
How do I propagate Penstemon?
Penstemon can be propagated by division, stem cuttings, and seeds.
