Creeping Jenny vs Mountain Mint Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Creeping Jenny
Lysimachia nummularia
Creeping Jenny (Lysimachia nummularia) is a perennial ground cover known for its trailing stems and round, coin-like leaves. It's primarily an outdoor plant, often used in gardens as a ground cover, in hanging baskets, or cascading over walls. While it can be grown indoors, it requires specific conditions to thrive and may not be as vigorous as when grown outdoors. People grow it for its attractive foliage and ability to quickly cover ground.
Mountain Mint
Pycnanthemum spp.
Mountain Mint encompasses several species of the genus Pycnanthemum, all native to North America. These herbaceous perennials are known for their strongly aromatic foliage and clusters of tiny, densely packed white or pink flowers that attract pollinators. They typically grow to be 1-3 feet tall and spread through rhizomes. While primarily outdoor plants, they are grown for their culinary and medicinal uses, as well as for attracting beneficial insects to gardens. Their minty fragrance is released when the leaves are crushed.

❓ Frequently Asked Questions — Comparing These Plants
Creeping Jenny
What are the light requirements for Creeping Jenny?
Creeping Jenny prefers bright, indirect light, but it can tolerate partial shade. In brighter light, the foliage will be more vibrant and the growth will be more vigorous. Avoid direct sunlight, especially during the hottest part of the day, as it can scorch the leaves. An east-facing window is ideal, but a north- or west-facing window can also work, as long as the plant receives sufficient light.
How do I care for Creeping Jenny?
Creeping Jenny thrives in bright, indirect light but can tolerate some shade. Water when the top inch of soil feels dry to the touch, avoiding overwatering which can lead to root rot. Well-draining soil is crucial. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain desired shape and encourage bushier growth.
How do I propagate Creeping Jenny?
Creeping Jenny is easily propagated through stem cuttings or layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Place the cutting in water or directly into moist potting mix. Roots should develop within a few weeks.
Mountain Mint
What are the light requirements for Mountain Mint?
Mountain Mint requires ample sunlight to thrive and produce abundant blooms. Aim for at least 6 hours of direct sunlight per day. In hotter climates, provide some afternoon shade to prevent leaf scorch. If growing indoors, place your Mountain Mint near a sunny window, such as a south-facing or east-facing window. Rotate the plant regularly to ensure even light exposure on all sides. Insufficient light can result in leggy growth, reduced blooming, and pale foliage. If natural light is insufficient, supplement with artificial grow lights. The ideal light intensity for Mountain Mint is between 2000-3000 foot-candles. Monitor the plant’s foliage for signs of light stress, such as yellowing or browning leaves.
How do I care for Mountain Mint?
Mountain Mint thrives in full sun to partial shade, requiring at least 6 hours of sunlight daily for optimal blooming. Water regularly, especially during dry spells, ensuring the soil remains consistently moist but not waterlogged. Well-draining soil is crucial to prevent root rot. Fertilize in spring with a balanced fertilizer to promote healthy growth and abundant blooms. Prune regularly to maintain shape and encourage bushier growth. Deadhead spent flowers to prolong the blooming period. Provide adequate air circulation to prevent fungal diseases. Monitor for pests such as aphids or spider mites and treat as needed. In colder climates, mulch around the base of the plant to protect the roots during winter. Propagate through division, stem cuttings, or seeds. Repot in spring every 1-2 years. The ideal humidity is moderate, around 40-60%. Provide fertilizer specifically for blooming plants to enhance flower production.
How do I propagate Mountain Mint?
Mountain Mint can be easily propagated through division, stem cuttings, or seeds. For division, carefully dig up an established plant and divide the root ball into smaller sections, ensuring each section has healthy roots and shoots. Repot the divisions into separate pots or plant directly into the garden. For stem cuttings, take 4-6 inch cuttings from healthy stems, 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 roots develop. For seeds, sow seeds indoors 6-8 weeks before the last frost. Keep the soil moist and provide bright, indirect light.
