Devil's Backbone vs Mazus Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
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.
Mazus
Mazus reptans
Mazus reptans is a low-growing, mat-forming perennial that typically reaches only a few inches in height. It spreads rapidly via creeping stems that root at the nodes. The plant features small, oval-shaped, toothed leaves that are typically green but can take on bronze hues in cooler weather. It produces small, trumpet-shaped flowers in shades of lavender, purple, or white, often with yellow markings in the throat. Primarily an outdoor plant, it is valued for its ability to quickly cover ground and suppress weeds in rock gardens, between stepping stones, and as a lawn substitute. While it can be attempted indoors, it requires very bright light and consistent moisture, making it challenging.

❓ Frequently Asked Questions — Comparing These Plants
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.
Mazus
What are the light requirements for Mazus?
Mazus prefers partial shade, especially in warmer climates. Direct sunlight can scorch the leaves, particularly during the hottest part of the day. Morning sun and afternoon shade are ideal. In cooler climates, Mazus can tolerate more sun exposure. When grown indoors, place Mazus near an east- or north-facing window to provide bright, indirect light. Avoid south-facing windows unless you can provide shade during peak sunlight hours. Insufficient light can lead to leggy growth and reduced flowering. Observe your plant closely and adjust its position as needed to ensure it receives the optimal amount of light.
How do I care for Mazus?
Mazus thrives in partial shade to full sun, depending on the climate. In hotter regions, provide afternoon shade to prevent scorching. Water regularly, especially during dry spells, keeping the soil consistently moist but not waterlogged. Well-draining soil is crucial to prevent root rot. Fertilize in spring with a balanced, slow-release fertilizer to promote healthy growth and abundant blooms. Trim back any dead or damaged foliage to encourage new growth. Mazus is generally low-maintenance, but regular watering and occasional fertilization will keep it looking its best. Monitor for pests like slugs and snails, and treat as needed. Mulching around the base of the plant helps retain moisture and suppress weeds. Deadheading spent flowers can encourage continued blooming throughout the season.
How do I propagate Mazus?
Mazus can be easily propagated by division, stem cuttings, or seed. For division, carefully dig up an established clump in the spring or fall and divide it into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in well-draining soil. To propagate from stem cuttings, take 4-6 inch cuttings from healthy stems in the spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix and keep them moist until they root. Seeds can be sown indoors 6-8 weeks before the last frost or directly outdoors in the spring after the danger of frost has passed. Keep the soil consistently moist until germination occurs.
