Canterbury Bells vs Orchid Cactus 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.
Orchid Cactus
Epiphyllum spp.
Orchid cacti are epiphytic or lithophytic plants, meaning they grow on other plants or rocks rather than in soil. They feature flattened, leaf-like stems (cladodes) that can be smooth or scalloped. These cacti are prized for their spectacular, large, fragrant flowers that typically bloom at night, hence the name 'Queen of the Night'. While they can be grown indoors, they require specific conditions to thrive and flower. People grow them for their unique foliage and stunning blooms.

❓ 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.
Orchid Cactus
What are the light requirements for Orchid Cactus?
Orchid Cacti require bright, indirect light to thrive and produce blooms. Direct sunlight can scorch the stems, so it’s best to place them near an east- or west-facing window where they receive filtered sunlight. Insufficient light can lead to leggy growth and a lack of flowering. If you don’t have access to natural light, you can supplement with a grow light, positioning it about 12-18 inches above the plant. Rotate the plant regularly to ensure even light exposure on all sides. During the winter months, when daylight hours are shorter, consider providing additional light to prevent the plant from becoming too dormant. A south-facing window with a sheer curtain to diffuse the light can also be suitable, especially during the winter.
How do I care for Orchid Cactus?
Orchid Cacti thrive in bright, indirect light. Water thoroughly only when the top inch of soil is dry, reducing watering frequency significantly during the winter dormancy. Use a well-draining potting mix specifically formulated for cacti and succulents. Maintain moderate humidity levels, and fertilize sparingly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Ensure good air circulation to prevent fungal diseases. Repot every 2-3 years, or when the plant becomes root-bound, into a slightly larger pot. Prune to remove dead or damaged stems and to encourage branching. Monitor for pests such as mealybugs and treat promptly. During the winter dormancy, keep the plant in a cooler location and reduce watering to almost none. Provide support for heavier growth to prevent breakage. Avoid direct sunlight, especially during the hottest part of the day, as it can scorch the stems.
How do I propagate Orchid Cactus?
Orchid Cacti can be propagated through stem cuttings. Allow the cut end to callus over for a few days before planting in well-draining soil. Keep the soil lightly moist until roots develop. Offsets can be separated from the parent plant and potted individually. Seeds can be sown in a seed-starting mix, but germination can be slow. Grafting is another method, often used to combine desirable traits from different varieties. For stem cuttings, choose healthy, mature stems. Dip the cut end in rooting hormone to encourage root development. Place the cutting in a warm, bright location, but avoid direct sunlight. Propagation is best done in the spring or summer.
