Blazing Star vs Globe Amaranth Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Blazing Star
Liatris spicata
Liatris spicata, commonly known as Blazing Star, is a perennial herbaceous plant prized for its striking vertical flower spikes. Native to moist meadows and prairies, it typically grows 2-5 feet tall. The plant features grass-like foliage and dense spikes of purple, pink, or white flowers that bloom from the top down, unlike most plants. It is primarily grown outdoors in gardens and naturalized areas for its pollinator-attracting qualities and unique floral display. While occasionally attempted indoors, it struggles due to high light requirements and dormancy needs.
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.

❓ Frequently Asked Questions — Comparing These Plants
Blazing Star
What are the light requirements for Blazing Star?
Blazing Star requires full sun for optimal growth and flowering, meaning at least six hours of direct sunlight each day. Insufficient sunlight can result in leggy growth, reduced flowering, and weaker stems. When planting Blazing Star in a garden, choose a location that receives ample sunlight throughout the day. If growing in containers, place them in a sunny spot, such as a south-facing patio or balcony. Rotate the containers periodically to ensure even light exposure on all sides of the plant. In regions with intense summer heat, some afternoon shade may be beneficial to prevent scorching of the foliage. Monitor the plant’s growth and adjust its location as needed to ensure it receives adequate sunlight.
How do I care for Blazing Star?
Blazing Star thrives in well-drained soil and full sun, requiring at least six hours of direct sunlight daily. Water deeply but infrequently, allowing the soil to dry out slightly between waterings. Avoid overwatering, as this can lead to root rot. Fertilize sparingly, using a balanced fertilizer in the spring to encourage healthy growth and abundant blooms. Deadhead spent flower spikes to promote continued blooming. In colder climates, provide winter protection by mulching around the base of the plant. Blazing Star is relatively low-maintenance and pest-resistant, making it an easy-to-grow addition to any garden. Ensure good air circulation to prevent fungal diseases. Divide established clumps every few years to rejuvenate the plant and prevent overcrowding. Regularly check for any signs of pests or diseases and address them promptly.
How do I propagate Blazing Star?
Blazing Star can be propagated by division, stem cuttings, or seeds.
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.
