Globe Amaranth vs Port Orford Cedar Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Globe Amaranth
Gomphrena globosa
Globe Amaranth is an annual flowering plant known for its globe-shaped flower heads that come in various colors, including purple, pink, red, orange, and white. Typically grown outdoors, it reaches a height of 1-2 feet. The plant has an upright growth habit with oval-shaped leaves. People grow it for its long-lasting blooms, which are excellent for fresh and dried flower arrangements. It thrives in warm weather and full sun, making it a popular choice for summer gardens. While technically possible to grow indoors, it requires very bright light and consistent care to mimic its natural outdoor environment.
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
Globe Amaranth
What are the light requirements for Globe Amaranth?
Globe Amaranth requires ample sunlight to thrive and produce abundant blooms. Aim for at least 6-8 hours of direct sunlight per day. A south-facing location is ideal, providing the most intense sunlight. If growing indoors, place the plant near a sunny window or supplement with grow lights. Insufficient light can result in leggy growth, fewer flowers, and duller colors. Rotate the plant regularly to ensure even light exposure on all sides. Plants grown in partial shade may still survive, but their flowering will be significantly reduced. Consider the intensity of the sun in your region, providing some afternoon shade in extremely hot climates to prevent scorching.
How do I care for Globe Amaranth?
Globe Amaranth is relatively easy to care for, thriving in warm, sunny conditions. Plant in well-draining soil that is moderately fertile. Water regularly, especially during dry periods, but avoid overwatering, which can lead to root rot. Fertilize every 4-6 weeks with a balanced fertilizer during the growing season to encourage abundant blooms. Deadhead spent flowers to promote continuous flowering. Provide full sun, ideally 6-8 hours per day. Protect from frost, as Globe Amaranth is sensitive to cold temperatures. Space plants adequately to allow for good air circulation. Monitor for pests such as aphids or spider mites and treat accordingly. Prune lightly to maintain shape and encourage branching. Avoid overhead watering to prevent fungal diseases.
How do I propagate Globe Amaranth?
Globe Amaranth is easily propagated from seed. Sow seeds indoors 6-8 weeks before the last frost or directly outdoors after the danger of frost has passed. For stem cuttings, take a 4-6 inch cutting from a healthy plant, remove the lower leaves, and dip the cut end in rooting hormone. Plant the cutting in moist potting mix and keep it humid until roots develop. Division is not typically used for Globe Amaranth. Keep soil moist but not soggy. Place in a warm, sunny location. Seedlings should emerge in 7-14 days. Transplant seedlings into individual pots once they are large enough to handle. Harden off seedlings before transplanting them outdoors.
