Globe Amaranth vs Liquidambar 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.
Liquidambar
Liquidambar styraciflua
Liquidambar styraciflua, or American Sweetgum, is a deciduous tree known for its vibrant fall foliage, transitioning from green to brilliant shades of red, orange, purple, and yellow. It typically grows to a height of 60-80 feet (18-24 meters) in its native habitat, with a pyramidal to oval crown. The leaves are star-shaped with 5-7 lobes. It is primarily an outdoor tree, valued for its ornamental appeal and timber production. While some may attempt to grow it indoors, it's not suitable due to its size and need for full sun and seasonal changes.

❓ 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.
Liquidambar
What are the light requirements for Liquidambar?
Liquidambar thrives in bright, indirect light. Direct sunlight can scorch the leaves, especially indoors where the light is intensified by glass. An east or west-facing window is ideal, providing ample light without the harshness of direct sun. If you don’t have access to a naturally bright location, supplement with grow lights. Rotate the plant regularly to ensure even growth on all sides. Insufficient light can lead to leggy growth and reduced leaf color vibrancy. Observe your plant closely; if the leaves appear pale or the stems are stretching, it needs more light. Consider using a light meter to accurately measure the light intensity.
How do I care for Liquidambar?
Caring for Liquidambar indoors requires mimicking its natural environment as closely as possible. Provide bright, indirect light, ideally near an east or west-facing window. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Maintain moderate humidity levels, especially during dry winter months, using a humidifier or pebble tray. Fertilize sparingly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Repot every 2-3 years into a slightly larger pot with well-draining potting mix. Prune as needed to maintain shape and remove any dead or damaged branches. Monitor for pests and address promptly. Ensure stable temperatures, avoiding sudden fluctuations or drafts. Proper pot size is crucial; select one that allows for root growth without being excessively large, which can lead to waterlogged soil.
How do I propagate Liquidambar?
Liquidambar can be propagated via stem cuttings or air layering, though success rates can vary. For stem cuttings, take a 4-6 inch cutting from new growth in spring or early summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist. Cover with a plastic bag to maintain humidity. Rooting can take several weeks. For air layering, make a shallow cut on a stem, wrap it with moist sphagnum moss, and cover it with plastic wrap. Secure the wrap tightly. Once roots develop, cut the stem below the roots and plant it in a pot. Both methods require patience and consistent care.
