Feather Reed Grass vs Lysimachia Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Feather Reed Grass
Calamagrostis x acutiflora
Feather Reed Grass is a cool-season perennial ornamental grass prized for its upright, columnar habit and feathery flower plumes. It typically grows to a height of 3-5 feet. The foliage is green and arching, providing a lovely backdrop for the prominent flower spikes that emerge in early summer. These plumes start out pinkish-purple, maturing to a golden-tan color that persists through winter, adding visual interest to the landscape. It is primarily an outdoor plant, valued for its architectural form and low maintenance needs in garden settings.
Lysimachia
Lysimachia nummularia
Lysimachia nummularia, commonly known as Creeping Jenny or Moneywort, is a perennial ground cover characterized by its trailing stems and rounded, coin-like leaves. It typically grows to only a few inches in height but can spread extensively. While primarily an outdoor plant, it is sometimes grown in hanging baskets or containers indoors. People grow it for its attractive foliage and ability to quickly cover ground, creating a lush, green carpet. Its vibrant green or golden foliage adds visual interest to gardens and landscapes. It is not ideally suited for long-term indoor growth.

💡 Pro Tips For Comparing These Plants
Feather Reed Grass Care Tips
Feather Reed Grass is primarily an outdoor plant. Indoor cultivation is extremely challenging due to its high light requirements and need for a dormancy period. It requires full sun and well-drained soil. It's best suited for outdoor gardens and landscapes.
- Plant in well-draining soil to prevent root rot.
- Provide full sun for optimal growth and flowering.
- Cut back foliage to the ground in late winter or early spring.
- Divide clumps every 3-4 years to maintain vigor.
- Water deeply but infrequently, allowing the soil to dry out between waterings.
Lysimachia Care Tips
Creeping Jenny is relatively easy to care for outdoors, but it can be challenging indoors due to its high light requirements and potential for aggressive growth. It needs very bright light and well-draining soil. Overwatering is a common problem. Regular pruning is needed to control its spread.
- Provide bright, indirect light with some direct sun exposure.
- Water thoroughly when the top inch of soil feels dry, but avoid overwatering.
- Fertilize regularly during the growing season.
- Prune regularly to control its spread and maintain its shape.

❓ Frequently Asked Questions — Comparing These Plants
Feather Reed Grass
What are the light requirements for Feather Reed Grass?
Feather Reed Grass requires at least 6 hours of direct sunlight per day for optimal growth and flowering. Full sun exposure ensures strong, upright stems and abundant plumes. Inadequate sunlight can result in weak, floppy stems and reduced flowering. Choose a location in your garden that receives full sun throughout the day.
How do I care for Feather Reed Grass?
Feather Reed Grass thrives in full sun and well-drained soil. Water regularly, especially during dry periods, but avoid overwatering, which can lead to root rot. Fertilize lightly in spring with a balanced fertilizer to promote healthy growth and abundant blooms. Cut back the foliage to a few inches above the ground in late winter or early spring before new growth emerges. Divide clumps every 3-4 years to maintain vigor and prevent overcrowding.
How do I propagate Feather Reed Grass?
Division is the easiest and most common method of propagating Feather Reed Grass. In early spring or late fall, dig up the clump and divide it into smaller sections, ensuring each section has healthy roots and shoots. Replant the divisions in well-drained soil and water thoroughly. Stem cuttings are not a viable propagation method for this grass.
Lysimachia
What are the light requirements for Lysimachia?
Lysimachia prefers partial to full sunlight, though the specific light needs vary depending on the species. Generally, plants need at least 4-6 hours of direct sunlight per day to thrive and produce abundant blooms. In hotter climates, providing some afternoon shade can prevent leaf scorch. Insufficient light can result in leggy growth, reduced flowering, and pale foliage.
How do I care for Lysimachia?
Lysimachia thrives in moist, well-draining soil. Water regularly, especially during dry periods, but avoid overwatering to prevent root rot. Plant in a location that receives partial to full sunlight, depending on the specific species. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer to encourage blooming. Prune regularly to maintain shape and remove any dead or damaged foliage.
How do I propagate Lysimachia?
Lysimachia can be propagated easily through division, stem cuttings, and, in some species, keikis.
