Pothos vs Purple Fountain Grass Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Pothos
Epipremnum aureum
Epipremnum aureum, commonly known as Pothos, is a popular evergreen vine prized for its ease of care and attractive foliage. Native to the Society Islands of French Polynesia, it's a hemiepiphyte in its natural habitat, climbing trees with aerial roots. Indoors, it's typically grown in hanging baskets or pots, with trailing stems that can reach several feet long. People grow it for its air-purifying qualities, aesthetic appeal, and adaptability to various indoor conditions. It is not naturally an indoor plant, but it adapts well.
Purple Fountain Grass
Pennisetum setaceum 'Rubrum'
Purple Fountain Grass is a striking ornamental grass prized for its arching, burgundy-purple foliage and bottlebrush-like flower plumes. It typically grows in a mounded form, reaching several feet in height and width. While technically a perennial in warmer climates, it is often grown as an annual in cooler regions due to its sensitivity to frost. It is primarily an outdoor plant, grown for its dramatic texture and color in gardens and landscapes. People grow it for its ornamental value, adding movement and visual interest to borders, containers, and mass plantings.

💡 Pro Tips For Comparing These Plants
Pothos Care Tips
Pothos is a low-maintenance plant that thrives in a variety of indoor conditions. It tolerates low light and infrequent watering, making it ideal for beginners. However, it is toxic to pets and requires occasional pruning to maintain its shape and size.
- Allow the soil to dry out slightly between waterings to prevent root rot.
- Provide bright, indirect light for optimal growth and variegation.
- Fertilize sparingly during the growing season to avoid fertilizer burn.
- Prune regularly to maintain desired shape and encourage bushier growth.
- Wipe leaves occasionally to remove dust and improve photosynthesis.
Purple Fountain Grass Care Tips
Purple Fountain Grass is primarily an outdoor plant and will struggle indoors due to its high light requirements. It needs full sun and well-draining soil. While it can be grown in containers, it requires regular watering and fertilization. Overwintering indoors is possible in colder climates, but the plant may not thrive.
- Plant in well-draining soil in a sunny location.
- Water deeply but infrequently, allowing the soil to dry out between waterings.
- Fertilize in spring with a balanced slow-release fertilizer.
- Cut back foliage in late fall or early spring.
- Protect from frost in colder climates.

❓ Frequently Asked Questions — Comparing These Plants
Pothos
What are the light requirements for Pothos?
Pothos prefers bright, indirect light. Avoid direct sunlight, which can scorch the leaves. An east-facing window is ideal, providing gentle morning sun. A north-facing window can also work, although growth may be slower. If placing near a south- or west-facing window, use a sheer curtain to filter the light. Insufficient light can lead to leggy growth and loss of variegation in variegated varieties. Rotate the plant regularly to ensure even growth on all sides. Artificial grow lights can supplement natural light, especially during winter months. Observe your plant for signs of light stress, such as pale leaves or sunburn.
How do I care for Pothos?
Pothos thrive in bright, indirect light but can tolerate low-light conditions. Water when the top inch of soil feels dry; avoid overwatering, which can lead to root rot. Use well-draining potting mix. Maintain moderate to high humidity; mist regularly or place near a humidifier. Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain desired shape and encourage bushier growth. Repot when the plant becomes root-bound. Keep temperatures between 65-85°F (18-29°C). Monitor for pests like spider mites and mealybugs, and treat promptly. Provide support for climbing if desired.
How do I propagate Pothos?
Pothos is easily propagated via stem cuttings. Take a cutting with at least one node (where a leaf emerges). Place the cutting in water, ensuring the node is submerged. Roots will typically develop within a few weeks. Once the roots are an inch or two long, plant the cutting in well-draining potting mix. Alternatively, you can plant the cutting directly into soil, keeping it consistently moist. Air layering involves encouraging roots to grow on a stem while it’s still attached to the parent plant. Division is less common but can be done by separating a large, multi-stemmed plant into smaller sections.
Purple Fountain Grass
What are the light requirements for Purple Fountain Grass?
Purple Fountain Grass requires at least 6-8 hours of direct sunlight per day to thrive and develop its characteristic vibrant purple foliage and abundant flower plumes. Insufficient sunlight can lead to leggy growth, faded color, and reduced flowering. When planting, choose a location that receives full sun throughout the day. If growing in containers, rotate the plant regularly to ensure even sun exposure on all sides. In hotter climates, some afternoon shade may be beneficial to prevent scorching, but avoid placing it in deep shade, which will hinder its growth. Supplemental lighting may be necessary if grown indoors during winter months.
How do I care for Purple Fountain Grass?
Purple Fountain Grass thrives in full sun and well-draining soil. Water thoroughly when the top inch of soil feels dry, but avoid overwatering, which can lead to root rot. Fertilize monthly during the growing season (spring and summer) with a balanced fertilizer to promote healthy growth and vibrant blooms. Prune away dead or damaged foliage in late winter or early spring before new growth emerges. In colder climates, treat it as an annual or bring it indoors during the winter. Provide adequate air circulation to prevent fungal diseases. Regularly inspect for pests like aphids or spider mites, and treat accordingly. Avoid planting in overly compacted or poorly draining soil. Mulching around the base can help retain moisture and suppress weeds. Protect from strong winds.
How do I propagate Purple Fountain Grass?
Purple Fountain Grass can be propagated by division. In early spring, carefully dig up the plant and divide the root ball into smaller clumps, ensuring each clump has healthy roots and foliage. Replant the divisions in well-draining soil and water thoroughly. Keep the soil consistently moist until the new plants are established. Division is the most reliable method. Seed propagation is possible but can be inconsistent in producing plants true to the ‘Rubrum’ cultivar. Stem cuttings are not typically used for propagating this grass. Keikis are not applicable as this plant doesn’t produce them. Ensure good air circulation to prevent fungal diseases after dividing.
