Hair Grass vs Mock Orange Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Hair Grass
Deschampsia cespitosa
Deschampsia cespitosa, or Tufted Hair Grass, is a cool-season perennial grass forming dense tussocks or tufts. It typically grows 2 to 4 feet tall and features fine-textured, arching leaves. The plant produces delicate, airy flower panicles in summer, which turn golden-tan as they mature, providing visual interest throughout the year. While primarily an outdoor ornamental grass, it's sometimes attempted indoors, but its need for bright light and cool temperatures makes it challenging. People grow it for its graceful form, year-round interest, and use in naturalistic landscapes and erosion control.
Mock Orange
Philadelphus spp.
Mock Orange is a deciduous shrub known for its fragrant, white flowers that resemble orange blossoms, hence the name. Typically grown outdoors, it features an upright, bushy habit and can reach considerable size. The plant is valued for its ornamental appeal, particularly during its blooming season in late spring to early summer. While some attempt to grow it indoors, it's primarily an outdoor plant and requires specific conditions that are difficult to replicate indoors. It is grown for its beautiful, fragrant flowers and attractive foliage.

💡 Pro Tips For Comparing These Plants
Hair Grass Care Tips
Tufted Hair Grass is primarily an outdoor plant. Indoor cultivation is challenging due to its high light requirements and need for cool temperatures. It requires well-draining soil, regular watering, and occasional fertilization. Maintaining adequate light levels indoors is the biggest hurdle.
- Provide well-draining soil to prevent root rot.
- Water deeply but infrequently, allowing the soil to dry out slightly between waterings.
- Cut back dead foliage in late winter or early spring.
- Avoid over-fertilizing, which can weaken the plant.
- Ensure adequate sunlight for optimal growth and flowering.
Mock Orange Care Tips
Mock Orange is primarily an outdoor plant and is challenging to grow indoors. It requires very bright light, specific humidity levels, and proper pruning to maintain its shape. It is not recommended for indoor growing unless you have a greenhouse or sunroom.
- Prune immediately after flowering to encourage new growth and prevent the plant from becoming leggy.
- Provide well-draining soil to prevent root rot.
- Water deeply but infrequently, allowing the soil to dry out slightly between waterings.
- Fertilize in the spring with a balanced fertilizer.
- Protect from strong winds, which can damage the delicate flowers.

❓ Frequently Asked Questions — Comparing These Plants
Hair Grass
What are the light requirements for Hair Grass?
Hair Grass has moderate to high light requirements, depending on the specific species. Eleocharis parvula (Dwarf Hair Grass) needs higher light levels than Eleocharis acicularis (Needle Hair Grass). Insufficient light can lead to leggy growth, yellowing, and eventual decline. Aim for at least 2-3 watts per gallon using fluorescent lighting or equivalent LED lighting. Place the Hair Grass in areas of the aquarium that receive direct light. Consider using a timer to maintain a consistent photoperiod of 8-10 hours per day. Monitor the plant’s growth and adjust the light intensity or duration as needed. Supplementing with CO2 injection further enhances the plant’s ability to utilize light.
How do I care for Hair Grass?
Hair Grass thrives in freshwater aquariums with stable water parameters. Maintain a temperature between 70-82°F (21-28°C) and a pH level of 6.0-7.5. Provide moderate to high lighting, depending on the specific species (e.g., Eleocharis parvula needs more light than Eleocharis acicularis). Supplement the water with CO2 injection for optimal growth, especially in densely planted tanks. Regular fertilization with liquid fertilizers containing macronutrients (nitrogen, phosphorus, potassium) and micronutrients (iron, trace elements) is crucial. Perform weekly water changes of 25-50% to maintain water quality and prevent the buildup of harmful substances. Trim the grass regularly to encourage dense growth and prevent shading. Ensure the substrate is nutrient-rich, using aquatic plant substrate or adding root tabs. Proper water circulation is essential to distribute nutrients and prevent algae growth. Monitor for signs of nutrient deficiencies, such as yellowing or stunted growth, and adjust fertilization accordingly.
How do I propagate Hair Grass?
Hair Grass is easily propagated through division. Carefully separate the plant into smaller clumps, ensuring each clump has roots and several blades. Replant the clumps in the substrate, spacing them a few centimeters apart. The plant will then spread via runners, creating a dense carpet. Cuttings in water are not a common method, but individual strands with small root sections can be placed in a small container with aquarium water and liquid fertilizer and kept under bright light until new growth appears. Replace the water every few days to prevent algae growth. Ensure the water is well-aerated. Once new roots have formed, the cutting can be planted in the substrate.
Mock Orange
What are the light requirements for Mock Orange?
Mock Orange requires at least six hours of direct sunlight daily to produce abundant blooms. While it can tolerate partial shade, too little sunlight will result in fewer flowers and leggy growth. A location with morning sun and afternoon shade is ideal in hotter climates. When planting, consider the amount of sunlight the area receives throughout the day and choose a spot that provides ample light. If your Mock Orange is struggling to bloom, try transplanting it to a sunnier location. Insufficient light can also lead to weak stems and pale foliage. Pay close attention to the plant’s overall health and adjust its position as needed to ensure it receives adequate sunlight.
How do I care for Mock Orange?
Mock Orange thrives in full sun to partial shade, requiring at least six hours of sunlight daily for optimal blooming. Water regularly, especially during dry periods, keeping the soil consistently moist but not waterlogged. Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant flowering. Prune after flowering to remove dead or crowded branches and to maintain shape. Mock Orange prefers well-draining soil with a slightly acidic to neutral pH. Protect from strong winds, as they can damage the delicate flowers. Mulch around the base of the plant to retain moisture and suppress weeds. Monitor for pests and diseases, such as aphids or powdery mildew, and treat accordingly. Provide adequate air circulation to prevent fungal problems.
How do I propagate Mock Orange?
Mock Orange can be propagated through division, stem cuttings, and layering. For division, carefully dig up the plant in early spring or fall and separate the root ball into smaller sections, each with its own set of roots and shoots. For stem cuttings, take 4-6 inch cuttings from new growth in late spring or early 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 they root. Layering involves bending a low-lying branch to the ground and covering it with soil. Once roots have formed, the layered branch can be separated from the parent plant. These methods can help produce new Mock Orange plants.
