Pittosporum vs Prostrate Rosemary Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Pittosporum
Pittosporum spp.
Pittosporum is a genus of evergreen shrubs and trees known for their glossy, leathery leaves and often fragrant flowers. They range in size from small shrubs to medium-sized trees, depending on the species. Pittosporums are primarily grown outdoors for their attractive foliage, which can be green, variegated, or even purple. Their dense growth habit makes them popular for hedging, screening, and ornamental landscaping. While some species can tolerate indoor conditions for a short period, they generally thrive outdoors with ample sunlight and air circulation. The appeal lies in their versatility and relatively low maintenance when planted in suitable climates.
Prostrate Rosemary
Salvia rosmarinus 'Prostratus'
Prostrate Rosemary is a low-growing, spreading cultivar of rosemary, known for its cascading growth habit. Unlike upright rosemary varieties, it forms a dense mat of foliage, typically reaching only 1-2 feet in height but spreading 2-4 feet wide. The leaves are needle-like, aromatic, and dark green. It's primarily grown outdoors as a ground cover, in rock gardens, or cascading over walls and containers. While it can be grown indoors, it requires very bright light and excellent air circulation to thrive. People grow it for its ornamental value, culinary uses, and fragrant foliage.

❓ Frequently Asked Questions — Comparing These Plants
Pittosporum
What are the light requirements for Pittosporum?
Pittosporum thrives in bright, indirect light. Insufficient light can lead to leggy growth and reduced foliage density. An east-facing window is often ideal, providing gentle morning sun. A south-facing window can also work, but be sure to filter the light with a sheer curtain to prevent leaf scorch. North-facing windows may not provide enough light, especially during the darker months. Rotate the plant regularly to ensure even light exposure on all sides. If natural light is inadequate, supplement with artificial grow lights. Place the grow lights 12-18 inches above the plant. Observe the plant for signs of light stress, such as pale leaves or stunted growth, and adjust its location accordingly.
How do I care for Pittosporum?
Pittosporum prefers bright, indirect light. Avoid direct sunlight, which can scorch the leaves. Water thoroughly when the top inch of soil feels dry to the touch, ensuring good drainage to prevent root rot. Use a well-draining potting mix. Maintain moderate humidity levels, especially during dry indoor conditions. Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain shape and encourage bushier growth. Repot every 1-2 years, or when the plant becomes root-bound, into a slightly larger pot. Monitor for pests such as aphids and spider mites, and treat promptly if detected. Provide stable temperatures, avoiding sudden fluctuations or drafts. Ensure proper air circulation around the plant. Wipe the leaves occasionally to remove dust and maintain their shine.
How do I propagate Pittosporum?
Pittosporum can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist. Cover with a plastic bag or humidity dome to maintain humidity. Roots should develop in 4-6 weeks. For air layering, make a small cut on a healthy stem and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Keep the moss moist. Roots should develop in a few weeks. Once roots are visible, cut the stem below the rooted area and plant it in a pot. Ensure the pot is the correct size and the plant is secured.
Prostrate Rosemary
What are the light requirements for Prostrate Rosemary?
Prostrate Rosemary needs at least 6 hours of direct sunlight each day to flourish. A south-facing window is ideal for indoor plants. If natural light is insufficient, supplement with a grow light. Insufficient light can lead to leggy growth and reduced flowering. Rotate the plant regularly to ensure even light exposure. Outdoor plants should be placed in a location that receives full sun throughout the day. Be mindful of intense afternoon sun in hot climates, which can scorch the leaves; provide some afternoon shade if necessary. The plant’s vibrant growth and abundant flowering are directly correlated to sufficient light exposure.
How do I care for Prostrate Rosemary?
Prostrate Rosemary thrives in full sun (at least 6 hours daily) and well-draining soil. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain freely. Avoid overwatering, as this can lead to root rot. Fertilize sparingly, using a balanced, slow-release fertilizer in spring and fall. Prune regularly to maintain shape and encourage bushier growth. Provide good air circulation to prevent fungal diseases. This plant is relatively drought-tolerant once established. Protect from frost in colder climates. Repot only when root-bound, using a well-draining potting mix. Monitor for pests like spider mites and aphids, treating as needed. Ensure proper drainage in containers to prevent waterlogging. Maintain moderate humidity levels. Provide adequate light during winter months.
How do I propagate Prostrate Rosemary?
Prostrate Rosemary is easily propagated through stem cuttings. Take 4-6 inch cuttings from new growth. Remove the lower leaves. Dip the cut end in rooting hormone. Plant the cuttings in well-draining potting mix. Keep the soil moist but not waterlogged. Cover with a plastic bag to increase humidity. Roots should develop in 4-6 weeks. Division is also possible by carefully separating a mature plant into smaller sections, ensuring each section has healthy roots. Keiki formation is not typical for rosemary; these methods are more commonly used.
