Cigar Plant vs Japanese Blood Grass Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Cigar Plant
Cuphea ignea
Cuphea ignea, commonly known as the Cigar Plant, is a small, evergreen shrub prized for its vibrant, tubular flowers that resemble lit cigars. Native to Mexico and Jamaica, it typically grows to a height of 1-2 feet. The plant features lance-shaped, glossy green leaves and produces numerous bright red-orange flowers with a white and black 'ash' tip. It is primarily grown outdoors in warm climates as a border plant, in containers, or as part of mixed beds. While it can be brought indoors, it requires very bright light to thrive and flower properly, making it challenging to maintain its vigor indoors.
Japanese Blood Grass
Imperata cylindrica 'Rubra'
Japanese Blood Grass is a striking ornamental grass known for its vibrant red foliage. It typically grows to a height of 1-2 feet. The leaves emerge green at the base and gradually turn to a deep, blood-red color towards the tips, intensifying in cooler weather. It is primarily an outdoor plant, valued for its dramatic color and texture in garden beds, borders, and containers. While it can be grown indoors, it requires very bright light and careful management to prevent it from becoming leggy and losing its vibrant color. It spreads via rhizomes and can be aggressive in some climates.

💡 Pro Tips For Comparing These Plants
Cigar Plant Care Tips
Cigar Plant is relatively easy to care for outdoors in warm climates. Indoors, it requires very bright light, which is often a challenge. Regular pruning and fertilization are necessary to maintain its shape and encourage flowering. It is not naturally an indoor plant and needs specific conditions to thrive.
- Provide at least 6 hours of direct sunlight daily for optimal flowering.
- Water thoroughly when the top inch of soil feels dry.
- Fertilize regularly during the growing season with a balanced liquid fertilizer.
- Prune regularly to maintain shape and encourage bushier growth.
- Protect from frost in colder climates.
Japanese Blood Grass Care Tips
Japanese Blood Grass is best suited for outdoor cultivation. Growing it indoors is challenging due to its high light requirements. It needs full sun to maintain its vibrant red color. It can also be an aggressive spreader in some climates, so containment may be necessary. Indoor plants require very bright light, careful watering, and occasional fertilization.
- Provide at least 6 hours of direct sunlight daily for best color.
- Water deeply but infrequently, allowing the soil to dry slightly between waterings.
- Avoid over-fertilizing, as it can reduce the red color.
- Divide the plant every few years to control its spread and rejuvenate growth.
- Monitor for pests and diseases, and treat promptly.

❓ Frequently Asked Questions — Comparing These Plants
Cigar Plant
What are the light requirements for Cigar Plant?
Cigar Plants need bright, indirect light to thrive and produce abundant blooms. Insufficient light can result in leggy growth, fewer flowers, and pale leaves. An east-facing window is ideal, providing gentle morning sunlight. West-facing windows can also work, but be careful to shield the plant from intense afternoon sun, which can scorch the leaves. A south-facing window may be suitable if you can filter the light with a sheer curtain. If you don’t have access to adequate natural light, you can supplement with a grow light. Place the plant under a grow light for 12-14 hours per day. Rotate the plant regularly to ensure even light exposure on all sides. Observe the plant closely for signs of light stress, such as sunburn or lack of blooming, and adjust its location accordingly.
How do I care for Cigar Plant?
Cigar Plants thrive in bright, indirect light; direct sunlight can scorch their leaves. Water thoroughly when the top inch of soil feels dry, but avoid overwatering, as this can lead to root rot. Ensure the pot has good drainage. Fertilize regularly during the growing season (spring and summer) with a balanced liquid fertilizer, diluted to half strength, to encourage blooming. Prune regularly to maintain shape and promote bushier growth. Remove spent flowers to encourage more blooms. Maintain a consistent temperature between 60-80°F (15-27°C). Cigar Plants prefer moderate to high humidity. Repot in spring if the plant becomes root-bound. Provide support if the plant becomes too leggy. Inspect regularly for pests such as aphids or spider mites, and treat promptly if necessary. Avoid placing near drafts or heating vents. Consider using a well-draining potting mix specifically formulated for flowering plants.
How do I propagate Cigar Plant?
Cigar Plants are easily propagated through stem cuttings. Take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant it in a pot filled with well-draining potting mix. Keep the soil moist but not soggy. Cover the pot with a plastic bag or humidity dome to increase humidity. Place the pot in a warm, bright location, but out of direct sunlight. Roots should develop in 2-4 weeks. Once the cutting has rooted, remove the plastic bag and gradually acclimate it to normal growing conditions. You can also propagate through division by carefully separating the root ball of a mature plant and repotting the divisions. Keiki propagation is not applicable to Cigar Plant.
Japanese Blood Grass
What are the light requirements for Japanese Blood Grass?
Japanese Blood Grass requires at least six hours of direct sunlight per day to achieve its most vibrant red coloration. While it can tolerate partial shade, insufficient light will result in greener leaves and less intense red hues. Ideally, plant it in a location that receives full morning sun and some afternoon shade in hotter climates to prevent leaf burn. When growing indoors, place it near a sunny window or supplement with grow lights. Rotate the plant regularly to ensure even light exposure on all sides. Consistent light exposure is crucial for maintaining the plant’s characteristic red foliage.
How do I care for Japanese Blood Grass?
Japanese Blood Grass thrives in well-draining soil and full sun to partial shade. Water thoroughly when the top inch of soil feels dry, but avoid overwatering, as this can lead to root rot. Fertilize in spring with a balanced, slow-release fertilizer to promote healthy growth and vibrant coloration. In hotter climates, provide some afternoon shade to prevent leaf scorch. Prune back dead or faded foliage in late winter or early spring before new growth emerges. Japanese Blood Grass is relatively low-maintenance, but regular monitoring for pests and diseases is essential. Ensure good air circulation to prevent fungal issues. Consistent care will result in a stunning display of red foliage throughout the growing season.
How do I propagate Japanese Blood Grass?
Japanese Blood Grass is most easily propagated by division. In early spring, carefully dig up the plant and divide the root clump into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in well-draining soil and water thoroughly. Keep the soil consistently moist until new growth emerges. Stem cuttings are not a reliable method for propagating this grass. Keiki formation is not applicable to Japanese Blood Grass. Division allows you to maintain the genetic characteristics of the ‘Red Baron’ cultivar.
