Globe Amaranth vs Norway Maple 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.
Norway Maple
Acer platanoides
The Norway Maple is a deciduous tree typically reaching heights of 20-30 meters (65-100 feet). It has a rounded crown and smooth gray bark that becomes furrowed with age. The leaves are palmate, with 5-7 lobes, and typically turn yellow in the fall, though some cultivars display orange or red hues. It's primarily an outdoor tree, valued for its shade, ornamental qualities, and adaptability to various soil conditions. It is not naturally an indoor plant and will not thrive indoors.

❓ 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.
Norway Maple
What are the light requirements for Norway Maple?
Norway Maples grown indoors need bright, indirect light to flourish. Direct sunlight can scorch their leaves, especially during the hottest parts of the day. An east-facing window that receives morning sun or a west-facing window with filtered afternoon light is ideal. If you don’t have access to sufficient natural light, supplement with grow lights. Insufficient light can lead to leggy growth and a lack of vibrant leaf color. Rotate your plant regularly to ensure all sides receive adequate light exposure, promoting even growth.
How do I care for Norway Maple?
The Norway Maple, when grown indoors, requires specific care to thrive. Place it in a location with bright, indirect sunlight. Water thoroughly when the top inch of soil is dry, ensuring proper drainage to prevent root rot. Maintain moderate humidity levels, especially during dry winter months, by misting the leaves or using a humidifier. Use a well-draining potting mix and fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain shape and size, removing any dead or diseased branches. Repot every 2-3 years into a slightly larger pot to accommodate root growth. Maintain stable temperatures between 60-75°F (15-24°C) and protect from drafts. Rotate the plant periodically to ensure even growth on all sides.
How do I propagate Norway Maple?
Norway Maples can be propagated through stem cuttings or air layering.
