Cestrum vs Mazus Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Cestrum
Cestrum nocturnum
Cestrum nocturnum, commonly known as Night-blooming jasmine, is a fast-growing evergreen shrub that can reach up to 12 feet tall outdoors. It is prized for its intensely fragrant flowers that bloom at night, releasing a sweet, powerful scent. The plant features slender, willow-like leaves and produces small, creamy-white flowers in clusters. While it can be grown in containers, it is primarily an outdoor plant and may struggle to thrive indoors due to its high light requirements and potential size. People grow it for its unique nocturnal fragrance and attractive foliage.
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
Cestrum
What are the light requirements for Cestrum?
Cestrum plants are sun-loving and require ample sunlight to thrive and produce abundant blooms. Ideally, they should receive at least 6 hours of direct sunlight each day. Inadequate sunlight can lead to leggy growth, reduced flowering, and pale foliage. When growing Cestrum indoors, place it near a south-facing window where it can receive maximum light exposure. If sufficient natural light is not available, consider supplementing with grow lights. Rotate the plant regularly to ensure even light exposure on all sides. During the summer months, Cestrum can be moved outdoors to a sunny location, but acclimate it gradually to prevent sunburn.
How do I care for Cestrum?
Cestrum thrives in well-draining soil and requires regular watering, especially during the growing season. Allow the top inch of soil to dry out between waterings to prevent root rot. Provide a sunny location with at least 6 hours of direct sunlight daily for optimal flowering. Fertilize regularly with a balanced fertilizer during the growing season (spring and summer) to encourage abundant blooms. Prune after flowering to maintain shape and promote new growth. Cestrum benefits from consistent humidity. Monitor for pests like aphids and spider mites, and treat promptly. Ensure good air circulation to prevent fungal diseases. In colder climates, Cestrum may need to be brought indoors or protected from frost. Repot every 1-2 years as needed. Pinch back new growth to encourage bushier growth.
How do I propagate Cestrum?
Cestrum can be propagated using stem cuttings. Take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant it in a well-draining potting mix. Keep the soil moist and provide indirect light. Roots should develop in a few weeks. Division is possible for some clump-forming varieties. Carefully separate the plant at the root ball and repot each section. Keiki propagation is not applicable to Cestrum. Cuttings are best taken in spring or early summer. Maintain high humidity around the cuttings to encourage rooting. Provide bottom heat for faster root development. Once rooted, gradually acclimate the new plants to brighter light.
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.
