Boston Ivy vs Prostrate Rosemary Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Boston Ivy
Parthenocissus tricuspidata
Boston Ivy is a vigorous, deciduous, woody vine known for its ability to cling to surfaces via adhesive tendrils. It's primarily grown outdoors as a climbing ornamental plant on walls, fences, and buildings. The leaves are typically three-lobed (tricuspidata meaning three-pointed) and turn brilliant shades of red and purple in the fall, providing spectacular autumn color. While occasionally grown indoors, it's challenging due to its need for bright light and its aggressive growth habit. People grow it for its rapid coverage and stunning fall foliage.
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
Boston Ivy
What are the light requirements for Boston Ivy?
Boston Ivy thrives in bright, indirect sunlight, but it can also tolerate partial shade. For optimal growth and vibrant fall colors, aim for at least 4-6 hours of sunlight per day. Direct sunlight can scorch the leaves, especially during the hottest part of the day, so providing some afternoon shade is beneficial. Indoors, place your Boston Ivy near an east-facing or west-facing window where it will receive ample light without being exposed to harsh direct sun. If you notice the leaves fading or the growth becoming leggy, it may not be receiving enough light, and you should consider moving it to a brighter location. Supplemental lighting, such as a grow light, can be used during the winter months or in areas with limited natural light.
How do I care for Boston Ivy?
Boston Ivy prefers well-draining soil and moderate watering. Water thoroughly when the top inch of soil feels dry, but avoid overwatering, which can lead to root rot. Provide bright, indirect sunlight for optimal growth and vibrant foliage color. Although it tolerates partial shade, full sun will enhance its fall colors. Prune regularly to control its size and shape, as it can grow vigorously. Fertilize sparingly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Provide a sturdy support structure, such as a trellis or wall, for it to climb. Monitor for pests like spider mites and aphids and treat promptly if detected. Ensure good air circulation to prevent fungal diseases. Repot in spring every 2-3 years, or as needed, using a slightly larger pot.
How do I propagate Boston Ivy?
Boston Ivy is easily propagated through stem cuttings or layering. For 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 pot filled with moist potting mix. Cover the pot with a plastic bag to create a humid environment and place it in a warm, bright location. Roots should develop in a few weeks. For layering, bend a long stem down to the soil and bury a section of it, leaving the tip exposed. Secure the buried section with a rock or garden staple. Once roots have formed, cut the stem from the parent plant and transplant the new plant. Both methods are best done in spring or summer.
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.
