Goat's Beard vs Monkey Grass Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Goat's Beard
Aruncus dioicus
Goat's Beard is a herbaceous perennial known for its impressive size and feathery plumes of creamy-white flowers. It typically grows to a height of 3-6 feet and forms a bushy clump. The plant features deeply divided, fern-like leaves that provide an attractive backdrop to the blooms. It is primarily an outdoor plant, thriving in woodland settings and moist meadows. People grow it for its ornamental value, adding height and texture to gardens, and for attracting pollinators.
Monkey Grass
Liriope muscari
Liriope muscari, commonly known as lilyturf or monkey grass, is a grass-like perennial often used as a ground cover or border plant. It features clumps of arching, strap-like, dark green leaves. While it resembles grass, it's not a true grass. It produces spikes of small, lavender to purple flowers in late summer, followed by blackish berries. Primarily an outdoor plant, it's valued for its low maintenance, drought tolerance, and ability to suppress weeds. It's rarely grown indoors due to its need for bright light and outdoor conditions.

❓ Frequently Asked Questions — Comparing These Plants
Goat's Beard
What are the light requirements for Goat's Beard?
Goat’s Beard prefers partial to full shade, thriving in locations that receive dappled sunlight or morning sun followed by afternoon shade. Direct sunlight, especially during the hottest part of the day, can scorch the leaves. Ideal placement is under the canopy of trees or on the north side of a building. If growing in a sunnier location, ensure the soil remains consistently moist to compensate for increased evaporation. Insufficient light will result in fewer blooms and leggy growth. Observe the plant for signs of stress, such as pale or yellowing leaves, and adjust its location accordingly. Avoid exposed areas with harsh afternoon sun.
How do I care for Goat's Beard?
Goat’s Beard thrives in partial to full shade, requiring at least 4 hours of indirect sunlight daily. Water deeply and regularly, especially during dry spells, ensuring the soil remains consistently moist but not waterlogged. Well-draining soil enriched with organic matter is essential. Fertilize in early spring with a balanced, slow-release fertilizer to promote healthy growth and abundant blooms. Prune spent flower plumes after blooming to maintain a tidy appearance and encourage reblooming. Mulch around the base of the plant to retain moisture and suppress weeds. Monitor for pests and diseases, addressing any issues promptly. Provide adequate air circulation to prevent fungal problems. Division every few years helps maintain vigor and prevents overcrowding.
How do I propagate Goat's Beard?
Goat’s Beard can be propagated through division, stem cuttings, and seeds. Division is best done in spring or fall. Carefully dig up the plant and separate the root ball into smaller clumps, ensuring each clump has healthy roots and foliage. Replant the divisions in well-draining soil. For stem cuttings, take 4-6 inch cuttings from new growth in spring. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in moist, well-draining soil. Keep the cuttings humid by covering them with a plastic bag or humidity dome. Seeds can be sown in spring or fall. Sow the seeds on the surface of the soil and lightly cover them with vermiculite. Keep the soil moist until germination occurs.
Monkey Grass
What are the light requirements for Monkey Grass?
Monkey Grass thrives in bright, indirect light. While it can tolerate some shade, too little light can lead to leggy growth and reduced vibrancy. Avoid direct sunlight, especially during the hottest parts of the day, as it can scorch the leaves. East-facing windows are ideal, providing gentle morning light. North-facing windows can also work if the light is sufficient. If you notice the leaves fading or stretching towards the light source, move the plant to a brighter location. Consider using grow lights if natural light is insufficient, especially during winter months. Rotate the plant regularly to ensure even light exposure on all sides.
How do I care for Monkey Grass?
Monkey Grass is relatively easy to care for. Provide bright, indirect light for optimal growth. Water regularly, keeping the soil consistently moist but not waterlogged. Ensure good drainage to prevent root rot. Fertilize lightly during the growing season (spring and summer) with a balanced liquid fertilizer. Prune away any dead or damaged foliage to maintain its appearance and encourage new growth. Monkey Grass prefers temperatures between 60-75°F (15-24°C) and appreciates high humidity. Mist the foliage regularly or use a humidifier to increase humidity levels, especially in dry environments. Repot every 2-3 years as needed, using a well-draining potting mix.
How do I propagate Monkey Grass?
Monkey Grass can be propagated through division, stem cuttings, and air layering.
