Canterbury Bells vs Ornamental Grass Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Canterbury Bells
Campanula medium
Canterbury Bells are biennials, meaning they complete their life cycle in two years. In the first year, they produce a rosette of foliage, and in the second year, they send up tall, upright flower stalks adorned with bell-shaped flowers. These flowers come in shades of blue, purple, pink, and white. They are primarily grown as outdoor garden plants, adding a cottage garden charm. While technically possible to grow indoors, they require very bright light and cool temperatures to thrive, making it challenging.
Ornamental Grass
Pennisetum setaceum
Pennisetum setaceum, commonly known as Fountain Grass, is a perennial grass prized for its graceful, arching foliage and bottlebrush-like flower plumes. Typically grown as an annual in cooler climates, it forms dense clumps of slender, linear leaves. The flower plumes, which appear in late summer and fall, add significant ornamental value. While primarily an outdoor plant, it is sometimes grown indoors, though it requires very bright light to thrive. Fountain grass is popular for its texture, movement in the wind, and overall aesthetic appeal in gardens and landscapes.

Canterbury Bells are best suited for outdoor gardens. Indoor cultivation is challenging due to their high light and cool temperature requirements. They are toxic to pets, requiring careful placement. Expect a shorter lifespan indoors.
- Provide adequate sunlight for optimal flowering.
- Ensure well-draining soil to prevent root rot.
- Deadhead spent flowers to encourage more blooms.
- Protect from strong winds, which can damage the tall flower stalks.
- Monitor for pests and diseases regularly.
Ornamental Grass Care Tips
Fountain Grass is primarily an outdoor plant and requires full sun to thrive. Growing it indoors is challenging due to its high light requirements. It needs well-draining soil, regular watering, and occasional fertilization. Indoor plants will likely be smaller and less vigorous than those grown outdoors.
- Provide at least 6 hours of direct sunlight daily, supplementing with grow lights if necessary.
- Use a well-draining potting mix to prevent root rot.
- Water thoroughly when the top inch of soil feels dry, but avoid overwatering.

❓ Frequently Asked Questions — Comparing These Plants
Canterbury Bells
What are the light requirements for Canterbury Bells?
Canterbury Bells flourish best in locations that receive full sun to partial shade. Ideally, they need at least six hours of direct sunlight daily for optimal blooming. In hotter climates, afternoon shade is beneficial to prevent scorching of the leaves and flowers. When grown indoors, place them near a sunny window, such as a south- or east-facing window. If natural light is insufficient, consider using grow lights to supplement their needs. Insufficient light can lead to leggy growth and reduced flowering. Rotate the plant regularly to ensure even light exposure on all sides.
How do I care for Canterbury Bells?
Canterbury Bells thrive in well-drained soil and prefer full sun to partial shade. Water regularly, keeping the soil consistently moist but not waterlogged, especially during the growing season. Fertilize every 2-3 weeks with a balanced liquid fertilizer to promote healthy growth and abundant blooms. Deadhead spent flowers to encourage further flowering. Provide support for tall varieties to prevent them from bending or breaking. Monitor for pests like aphids and slugs, and treat as needed. Ensure good air circulation to prevent fungal diseases. In colder climates, provide winter protection or grow as an annual. They prefer moderate humidity.
How do I propagate Canterbury Bells?
Canterbury Bells can be propagated by seed, division, or basal cuttings.
Ornamental Grass
What are the light requirements for Ornamental Grass?
Ornamental grasses require ample sunlight to thrive and produce their characteristic flower plumes. Aim for at least six hours of direct sunlight per day. A south-facing window is ideal for indoor plants. Insufficient light can result in leggy growth, poor flowering, and faded foliage color. If your grass is not receiving enough natural light, consider supplementing with a grow light. Rotate the plant regularly to ensure even light exposure on all sides. Some varieties can tolerate partial shade, but full sun is generally preferred for optimal performance. Observe your plant closely and adjust its location as needed to provide the best possible light conditions.
How do I care for Ornamental Grass?
Ornamental grasses thrive with regular care. Provide them with at least six hours of direct sunlight daily for optimal growth and flowering. Water deeply but infrequently, allowing the soil to dry out slightly between waterings. Fertilize sparingly in the spring with a balanced fertilizer to encourage healthy growth and bloom production. Prune back dead or damaged foliage in late winter or early spring before new growth emerges. Ensure good air circulation to prevent fungal diseases. Amend heavy clay soils with organic matter to improve drainage. Mulch around the base of the plant to retain moisture and suppress weeds. Monitor for pests and diseases and treat promptly. Repot container-grown grasses every few years to refresh the soil and provide more space for roots. Maintain moderate humidity levels, especially for indoor plants.
How do I propagate Ornamental Grass?
Ornamental grasses can be propagated through division. In early spring or fall, dig up the plant and carefully separate the root ball into smaller clumps. Each clump should have healthy roots and foliage. Replant the divisions in well-draining soil. Water thoroughly and keep the soil moist until new growth emerges. Stem cuttings are less common but can be taken in spring. Take 4-6 inch cuttings from new growth, remove lower leaves, and root in water or moist potting mix. Keikis (small plantlets that grow on the flower stalks) are rare but can be carefully removed and potted up. Provide bright, indirect light and consistent moisture to encourage rooting.
