English Lavender vs Japanese Forest Grass Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
English Lavender
Lavandula angustifolia
English Lavender is a perennial shrub known for its fragrant flowers and aromatic foliage. It typically grows to a height of 1-3 feet. The plant features narrow, gray-green leaves and produces spikes of purple flowers in the summer. It is primarily an outdoor plant, thriving in sunny, well-drained locations. People grow it for its ornamental value, fragrance, and use in aromatherapy and culinary applications. While it can be attempted indoors, it requires very specific conditions to thrive.
Japanese Forest Grass
Hakonechloa macra
Hakonechloa macra, commonly known as Japanese Forest Grass, is a deciduous perennial grass prized for its graceful, arching foliage. It forms cascading mounds of slender, bamboo-like leaves that create a soft, flowing texture in the garden. While primarily an outdoor plant, it is sometimes grown indoors, though it can be challenging. Its popularity stems from its elegant appearance, shade tolerance, and ability to add movement and texture to landscapes. The cultivar 'Aureola' is particularly popular for its golden-yellow variegated leaves. It is not naturally an indoor plant and requires specific conditions to thrive inside.

❓ Frequently Asked Questions — Comparing These Plants
English Lavender
What are the light requirements for English Lavender?
English Lavender requires at least six to eight hours of direct sunlight per day to thrive and produce abundant blooms. Insufficient light can result in leggy growth, reduced flowering, and weaker plants. When grown indoors, place Lavender near a south-facing window where it can receive the most intense sunlight. If natural light is limited, supplement with grow lights to ensure adequate illumination. Rotate the plant regularly to ensure even exposure to light on all sides. In hot climates, some afternoon shade may be beneficial to prevent scorching. Monitor the plant for signs of light stress, such as pale leaves or elongated stems, and adjust its placement accordingly.
How do I care for English Lavender?
English Lavender thrives in full sun and well-draining soil. Water deeply but infrequently, allowing the soil to dry out completely between waterings. Overwatering is a common cause of root rot. Fertilize sparingly, using a balanced fertilizer in the spring. Prune annually after flowering to maintain shape and encourage bushier growth. Provide good air circulation to prevent fungal diseases. Protect from frost in colder climates. Choose a pot with drainage holes and use a well-draining potting mix specifically formulated for Mediterranean plants. Regularly remove spent flowers to encourage further blooming. Monitor for pests such as aphids or spider mites and treat accordingly. Maintain moderate humidity levels. Provide 6-8 hours of direct sunlight daily for optimal growth and flowering.
How do I propagate English Lavender?
Lavender can be propagated through stem cuttings or division. For stem cuttings, take 4-6 inch cuttings from new growth in the spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix and keep them moist until rooted. Rooting typically takes 4-6 weeks. For division, carefully dig up the plant in the spring or fall and divide the root ball into smaller sections. Each section should have healthy roots and foliage. Replant the divisions in well-draining soil and water thoroughly. Ensure the new plants receive adequate sunlight and protection from frost. Lavender can also be propagated from seed, but it is a slower and less reliable method.
Japanese Forest Grass
What are the light requirements for Japanese Forest Grass?
Japanese Forest Grass prefers partial to full shade, requiring protection from intense, direct sunlight, especially during the hottest part of the day. Morning sun is tolerated, but harsh afternoon sun can scorch the delicate foliage. Ideally, aim for 2-4 hours of dappled sunlight or bright, indirect light. In hotter climates, full shade is best. When grown indoors, place the plant near a north-facing window or in a location with filtered light. Insufficient light can result in less vibrant foliage color and weaker growth. Observe the plant for signs of stress, such as leaf burn or faded color, and adjust its location accordingly.
How do I care for Japanese Forest Grass?
Japanese Forest Grass thrives in partial to full shade with well-draining soil that retains moisture. Water regularly, especially during dry periods, keeping the soil consistently moist but not soggy. Fertilize in spring with a balanced, slow-release fertilizer to encourage healthy growth and vibrant color. Avoid over-fertilizing, as this can lead to leggy growth. Prune away any dead or damaged foliage in early spring. Provide protection from harsh winds and intense afternoon sun. Mulch around the base of the plant to retain moisture and suppress weeds. Monitor for pests, such as slugs and snails, and treat as needed. Deadhead spent flower stalks to maintain a tidy appearance. In colder climates, provide winter protection by mulching heavily around the base of the plant. Ensure good air circulation to prevent fungal diseases.
How do I propagate Japanese Forest Grass?
Japanese Forest Grass is best propagated by division in early spring or fall. Carefully dig up the plant and separate it into smaller clumps, ensuring each clump has healthy roots and foliage. Replant the divisions in well-draining soil, spacing them appropriately. Water thoroughly and keep the soil consistently moist until the plants are established. Stem cuttings are not typically used for propagation. Keikis are not produced by this plant. Division is the most reliable method, allowing you to easily replicate the parent plant and establish new plants quickly. Ensure the divisions are handled gently to minimize stress and promote successful rooting.
