Celery vs Devil's Backbone Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Celery
Apium graveolens
Celery is a biennial plant, typically cultivated as an annual, characterized by its fibrous stalks and leafy green tops. It grows upright, reaching heights of 12-18 inches. While primarily an outdoor garden vegetable, it's grown for its edible stalks, leaves, and root (celeriac). It requires specific conditions to thrive and is not typically grown indoors due to space and light requirements. People grow celery for culinary purposes, adding it to salads, soups, and as a raw snack.
Devil's Backbone
Euphorbia tithymaloides
Euphorbia tithymaloides, commonly known as Devil's Backbone, is a succulent shrub characterized by its unique zig-zagging stems and fleshy, ovate leaves. It can grow up to 6-8 feet tall outdoors, but typically remains smaller when grown as a houseplant. The leaves are typically green, but variegated forms with white or pink edges are also popular. Small, slipper-shaped red or pink flowers appear sporadically. It's grown for its unusual form and ease of care, though it's important to note its toxicity.

❓ Frequently Asked Questions — Comparing These Plants
Celery
What are the light requirements for Celery?
Celery requires a significant amount of light to thrive, ideally 6-8 hours of direct sunlight per day. If growing indoors, place your celery plant near a south-facing window where it can receive ample sunlight. If natural light is insufficient, supplement with grow lights to prevent leggy growth and ensure robust development. Insufficient light can lead to weak stalks and poor flavor. Rotate the plant regularly to ensure even light exposure on all sides. Watch for signs of etiolation (stretching) which indicates the plant is not receiving enough light.
How do I care for Celery?
Celery thrives in full sun to partial shade, requiring at least 6 hours of sunlight daily. Water deeply and regularly, keeping the soil consistently moist but not waterlogged; never let the soil dry out completely. Plant in well-draining soil that is rich in organic matter. Fertilize every 2-3 weeks with a balanced liquid fertilizer, especially during the growing season. Maintain a consistent temperature between 60-70°F (15-21°C). Celery prefers high humidity; mist regularly or use a humidifier. Protect from frost. Harvest stalks as needed once they reach a usable size. Remove any yellowing or damaged leaves to encourage healthy growth. Regularly check for pests like aphids and spider mites, and treat promptly.
How do I propagate Celery?
Celery is most effectively propagated from seeds, as it is typically grown for its stalks and not for extensive vegetative propagation.
Devil's Backbone
What are the light requirements for Devil's Backbone?
Devil’s Backbone thrives in bright, indirect light. It can tolerate some direct sunlight, especially in the morning or late afternoon, but avoid prolonged exposure to intense midday sun, which can scorch the leaves. An east-facing window is often ideal, providing ample morning light without the harshness of the afternoon sun. A south- or west-facing window can also work, but be sure to filter the light with a sheer curtain or move the plant slightly away from the window to prevent sunburn.
How do I care for Devil's Backbone?
Devil’s Backbone is a relatively easy-to-care-for succulent. Provide it with bright, indirect light, although it can tolerate some direct sun. Water thoroughly only when the soil is completely dry to the touch, typically every 2-4 weeks, depending on environmental conditions. Ensure the pot has drainage holes to prevent root rot. Use a well-draining succulent or cactus potting mix.
How do I propagate Devil's Backbone?
Devil’s Backbone is easily propagated through leaf cuttings, offsets, and stem cuttings.
