Creeping Jenny vs Kale 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.
Kale
Brassica oleracea var. sabellica
Kale is a leafy green vegetable belonging to the cabbage family. It's characterized by its curly or frilly leaves, which can range in color from dark green to purple. Kale is primarily grown outdoors as a cool-season crop, thriving in gardens and farms. People grow kale for its nutritional value, as it's packed with vitamins and minerals. It's a versatile vegetable used in salads, smoothies, soups, and as a cooked side dish. While technically possible to grow indoors, it requires very bright light and cool temperatures to thrive, making it challenging for most home environments.

❓ 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.
