Japanese Spurge vs Port Orford Cedar Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Japanese Spurge
Pachysandra terminalis
Pachysandra terminalis, commonly known as Japanese Spurge, is a low-growing, evergreen groundcover. It spreads via rhizomes, forming a dense carpet of foliage. The leaves are dark green, leathery, and toothed near the tips. Small, white, bottlebrush-like flowers appear in spring, though they are not particularly showy. It is primarily grown as an outdoor groundcover for shady areas where grass is difficult to establish. While sometimes attempted indoors, it struggles due to its need for specific outdoor conditions and dormancy periods.
Port Orford Cedar
Chamaecyparis lawsoniana
Port Orford Cedar is a large evergreen coniferous tree, typically found in its native range. It boasts scale-like foliage that is aromatic when crushed. The tree has a conical growth habit and can reach impressive heights in the wild. While highly valued for its timber and ornamental qualities, it is primarily an outdoor tree. Growing it indoors is extremely challenging due to its need for full sun, cold winters, and susceptibility to root rot in containers. People grow it outdoors as a specimen tree, for hedging, or in large gardens.

❓ Frequently Asked Questions — Comparing These Plants
Japanese Spurge
What are the light requirements for Japanese Spurge?
Japanese Spurge thrives in partial to full shade, making it an excellent choice for areas under trees or on the north side of buildings. While it can tolerate some morning sun, intense afternoon sun can scorch its leaves. Aim for a location that receives dappled sunlight or filtered shade throughout the day. If growing indoors, place it near a north-facing window or in a room with indirect light. Insufficient light can result in leggy growth and reduced blooming. Monitor the leaves for signs of stress, such as yellowing or browning, which may indicate too much or too little light.
How do I care for Japanese Spurge?
Japanese Spurge prefers partial to full shade and well-drained soil. Water regularly, especially during dry periods, but avoid overwatering, which can lead to root rot. Fertilize in early spring with a balanced, slow-release fertilizer to encourage healthy growth and blooming. Prune lightly after flowering to maintain shape and density. Remove any dead or damaged foliage. Mulch around the plants to retain moisture and suppress weeds. Monitor for pests, such as spider mites, and treat as needed. Ensure good air circulation to prevent fungal diseases. Protect from harsh winter winds in colder climates. Repotting is rarely necessary.
How do I propagate Japanese Spurge?
Japanese Spurge is easily propagated through division or stem cuttings. For division, carefully dig up an established plant and separate it into smaller sections, ensuring each section has roots. Replant the divisions in well-draining soil. For stem cuttings, take 4-6 inch cuttings from healthy stems. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a moist potting mix. Keep the cuttings in a humid environment until roots develop. Rooting typically takes several weeks. Keep the soil moist during the rooting process. Propagating from stem cuttings is best done in spring or early summer.
Port Orford Cedar
What are the light requirements for Port Orford Cedar?
Port Orford Cedar thrives in bright, indirect light. Avoid exposing it to direct sunlight, especially during the hottest part of the day, as this can scorch the delicate foliage. An east-facing window is generally ideal, providing gentle morning sun. A north- or west-facing window can also work if the plant receives sufficient ambient light.
How do I care for Port Orford Cedar?
Port Orford Cedar, while relatively easy to care for indoors, requires attention to certain key factors. Provide bright, indirect light; direct sunlight can scorch the foliage. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Maintain a moderate humidity level, ideally between 40-60%.
How do I propagate Port Orford Cedar?
Port Orford Cedar can be propagated through stem cuttings or air layering, although success rates can vary.
