Boxwood vs Jerusalem Sage Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Boxwood
Buxus spp.
Boxwood is a genus of about 70 species in the family Buxaceae. These are evergreen shrubs or small trees, reaching 1-12 meters tall. The leaves are small, opposite, leathery, and ovate. Boxwoods are popular for formal gardens, hedges, topiary, and containers. They are known for their dense, fine-textured foliage and ability to be shaped. While primarily outdoor plants, they are sometimes brought indoors for short periods, especially during the holidays, but long-term indoor cultivation is challenging.
Jerusalem Sage
Phlomis fruticosa
Jerusalem Sage (Phlomis fruticosa) is a small, rounded evergreen shrub typically growing to 1-4 feet tall and wide. It features wrinkled, gray-green, woolly leaves that are opposite and ovate. Native to the Mediterranean, it thrives in hot, dry conditions. It's primarily grown outdoors for its drought tolerance, attractive foliage, and vibrant yellow, hooded flowers that bloom in whorls around the stems in summer. While it can be attempted indoors, it requires very bright light and excellent drainage to avoid root rot, making it challenging to maintain as a houseplant.

Boxwood is primarily an outdoor plant and requires specific conditions to thrive indoors. It needs very bright light, well-draining soil, and careful watering to prevent root rot. Maintaining adequate humidity is also crucial. Long-term indoor survival is challenging.
- Provide consistent bright light to prevent leggy growth.
- Water thoroughly but allow the soil to dry slightly between waterings.
- Maintain adequate humidity by misting regularly or using a humidifier.
- Prune regularly to maintain shape and encourage dense growth.
- Monitor for pests and diseases and treat promptly.
Jerusalem Sage Care Tips
Jerusalem Sage is primarily an outdoor plant that requires full sun and excellent drainage. Indoor cultivation is challenging due to its high light requirements and susceptibility to root rot. It needs very bright light, infrequent watering, and well-draining soil to survive indoors. It is also toxic to pets.
- Ensure excellent drainage to prevent root rot.
- Provide at least 6-8 hours of direct sunlight daily.
- Water deeply but infrequently, allowing the soil to dry out completely between waterings.
- Prune lightly after flowering to maintain shape and encourage bushier growth.
- Avoid over-fertilizing, as this can lead to leggy growth and reduced flowering.

❓ Frequently Asked Questions — Comparing These Plants
Boxwood
What are the light requirements for Boxwood?
Boxwood prefers bright, indirect light when grown indoors. Direct sunlight can scorch the leaves, causing them to turn brown. An east-facing window is often ideal, providing gentle morning light. A north-facing window may also work, but the plant might need supplemental light, especially during winter. If using a south- or west-facing window, place the plant several feet away from the window or use sheer curtains to filter the light. Signs of insufficient light include leggy growth and pale leaves. Rotate the plant regularly to ensure all sides receive adequate light. Consider using a grow light if natural light is limited.
How do I care for Boxwood?
Boxwood thrives indoors with proper care. Provide bright, indirect light; avoid direct sunlight which can scorch the leaves. Water thoroughly when the top inch of soil is dry, ensuring good drainage to prevent root rot. Maintain moderate humidity, ideally between 40-60%. Fertilize sparingly with a balanced, slow-release fertilizer during the growing season (spring and summer). Prune regularly to maintain the desired shape and remove any dead or yellowing foliage. Repot every 2-3 years into a slightly larger pot with well-draining potting mix. Maintain stable temperatures between 60-75°F (15-24°C). Rotate the plant regularly to ensure even growth on all sides. Monitor for pests such as spider mites and treat promptly if detected. Avoid drafts and sudden temperature changes. Use a pot with drainage holes.
How do I propagate Boxwood?
Boxwood can be propagated through stem cuttings or air layering. For stem cuttings, take 4-6 inch cuttings from new growth in late spring or early summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a pot filled with well-draining potting mix. Keep the soil moist and cover the pot with a plastic bag to maintain humidity. Roots should develop in 6-8 weeks. For air layering, make a shallow cut on a stem and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Once roots have formed, cut the stem below the roots and plant it in a pot.
Jerusalem Sage
What are the light requirements for Jerusalem Sage?
Jerusalem Sage requires at least six hours of direct sunlight per day to thrive. Full sun exposure is crucial for optimal flowering and dense foliage growth. Insufficient light can lead to leggy growth, reduced blooming, and paler foliage. In hotter climates, some afternoon shade can be beneficial to prevent scorching of the leaves, especially during the hottest months. When planting, choose a location that receives unobstructed sunlight throughout the majority of the day. If grown in containers, rotate the plant regularly to ensure even light exposure on all sides. Adequate light is essential for the plant’s overall health and vigor.
How do I care for Jerusalem Sage?
Jerusalem Sage thrives with minimal care once established. Plant in well-draining soil and provide full sun for optimal growth and flowering. Water deeply but infrequently, allowing the soil to dry out between waterings to prevent root rot. Fertilize sparingly, using a balanced fertilizer in early spring to encourage blooming. Prune lightly after flowering to maintain shape and promote bushier growth. Jerusalem Sage is drought-tolerant and prefers warm climates. Protect from excessive winter moisture in colder regions. Ensure good air circulation to prevent fungal diseases. Monitor for pests like aphids, but infestations are generally rare. Provide support if the plant becomes leggy. Avoid over-fertilizing, which can reduce flowering.
How do I propagate Jerusalem Sage?
Jerusalem Sage can be easily propagated through several methods. Division: Carefully dig up a mature plant and divide the root ball into smaller sections, each with healthy roots and stems. Replant the divisions in well-draining soil. Stem Cuttings: Take 4-6 inch stem cuttings from new growth, removing the lower leaves. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the soil moist until roots develop. Keiki (unlikely in this species): Jerusalem Sage doesn’t typically produce keiki. Keep cuttings in a humid environment to encourage root growth. Propagation is best done in spring or early summer.
