Licorice Plant vs Moonseed Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Licorice Plant
Glycyrrhiza glabra
Glycyrrhiza glabra, commonly known as licorice, is a perennial herbaceous plant that grows to about 1 meter (3 feet) tall. It features pinnate leaves and pea-like flowers, typically purple to pale blue. The plant is primarily cultivated for its rhizomes and roots, which contain glycyrrhizin, a compound responsible for its characteristic sweet flavor. Licorice is mainly grown outdoors in well-drained soil and full sun. While it can be attempted indoors, it's challenging to replicate its ideal growing conditions, and it may not thrive.
Moonseed
Menispermum canadense
Common Moonseed is a deciduous, twining vine that can grow up to 12 meters long. It is characterized by its round, palmately lobed leaves and small, greenish-white flowers that bloom in the summer. The plant produces distinctive, crescent-shaped fruits (drupes) that resemble moon segments, hence the name. It is primarily an outdoor plant, found in moist woodlands, thickets, and along riverbanks. People may grow it for its ornamental foliage and interesting fruit, but caution is necessary due to its toxicity.

❓ Frequently Asked Questions — Comparing These Plants
Licorice Plant
What are the light requirements for Licorice Plant?
Licorice Plant thrives in bright, indirect light. Too much direct sunlight can scorch the leaves, while insufficient light can lead to leggy growth and faded foliage color. An east-facing window is often ideal, providing gentle morning sun. A south- or west-facing window can also work, but be sure to filter the light with sheer curtains or blinds, especially during the hottest part of the day.
How do I care for Licorice Plant?
Licorice Plant thrives in well-draining soil. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain. Provide bright, indirect light for optimal growth, though it can tolerate some direct sun, especially in the morning. These plants prefer moderate temperatures, ideally between 60-75°F (15-24°C). Fertilize lightly every 4-6 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength.
How do I propagate Licorice Plant?
Licorice Plant is easily propagated through stem cuttings and layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant it in moist, well-draining potting mix. Cover with a plastic bag or humidity dome to maintain moisture. Keep in bright, indirect light until roots develop, usually within 2-4 weeks.
Moonseed
What are the light requirements for Moonseed?
Moonseed thrives in bright, indirect light. Insufficient light can lead to leggy growth and reduced flowering. An east-facing window is ideal, providing gentle morning sun. Avoid harsh, direct sunlight, which can scorch the leaves. If growing indoors, supplement with grow lights if natural light is limited. Rotate the plant regularly to ensure even light exposure on all sides. When planting outdoors, choose a location that receives partial shade, especially during the hottest part of the day. The plant can tolerate more sun in cooler climates.
How do I care for Moonseed?
Moonseed requires well-draining soil and a support structure like a trellis or fence to climb. Water regularly, allowing the top inch of soil to dry out between waterings. Provide bright, indirect light for optimal growth, but it can tolerate some shade. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer. Prune regularly to control its size and shape, removing any dead or damaged vines. Ensure good air circulation to prevent fungal diseases. Monitor for pests like aphids and spider mites and treat as needed. Repot every 1-2 years in spring. Be careful when handling the plant as the berries are toxic.
How do I propagate Moonseed?
Moonseed can be propagated by stem cuttings or layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a pot filled with well-draining potting mix. Keep the soil moist and provide indirect light. Roots should develop in a few weeks. For layering, bend a long stem down to the soil and bury a portion of it. Keep the soil moist. Once roots develop, sever the layered stem from the parent plant. Transplant the new plant into its own pot.
