Italian Arum vs Licorice Plant Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Italian Arum
Arum italicum
Italian Arum is a herbaceous perennial known for its striking foliage and distinctive spadix and spathe flower structure. It emerges in autumn with arrow-shaped, glossy green leaves often marked with prominent white veins. In late spring, it produces a creamy-white spathe surrounding a yellow spadix, followed by clusters of bright orange-red berries. Primarily an outdoor plant, it thrives in woodland settings. People grow it for its ornamental foliage and colorful berries, which add visual interest to gardens, especially during the dormant winter months. It is not naturally suited for indoor environments.
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.

❓ Frequently Asked Questions — Comparing These Plants
Italian Arum
What are the light requirements for Italian Arum?
Italian Arum prefers partial to full shade, making it an ideal plant for areas with limited sunlight. While it can tolerate some morning sun, prolonged exposure to direct sunlight can scorch the leaves. When grown indoors, place the plant near a north-facing window or in a location that receives filtered light. If leaves start to turn pale or yellow, it may be receiving too much light.
How do I care for Italian Arum?
Italian Arum thrives in partial to full shade, requiring minimal direct sunlight. Plant in well-draining soil rich in organic matter. Water regularly during the growing season, keeping the soil consistently moist but not waterlogged. Reduce watering significantly during the dormant period in summer. Fertilize in early spring with a balanced, slow-release fertilizer to promote healthy growth and flowering.
How do I propagate Italian Arum?
Italian Arum can be propagated by division or by seed. Division is the most common and easiest method. In late summer or early fall, carefully dig up the plant and gently separate the corms. Ensure each division has healthy roots and foliage. Replant the divisions in well-draining soil, spacing them appropriately. Water thoroughly after planting. Seeds can be collected from the ripe berries, but germination can be slow and inconsistent.
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.
