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.

Nasturtium

Nasturtium

Tropaeolum majus

Nasturtium (Tropaeolum majus) is an annual flowering plant known for its vibrant, edible flowers and peppery-flavored leaves. It features round, shield-shaped leaves and spurred flowers in shades of orange, yellow, and red. Typically grown outdoors in gardens and containers, it's valued for its ornamental appeal, culinary uses, and ability to attract pollinators. It's not ideally suited as a long-term indoor plant due to its high light requirements and sprawling growth habit.

💡 Pro Tips For Comparing These Plants

Licorice Plant Care Tips

Licorice is primarily an outdoor plant and requires full sun and well-drained soil. Growing it indoors is challenging due to its high light requirements and potential for rhizomatous spread. It also poses a toxicity risk to pets. Indoor cultivation requires careful attention to light, watering, and potential toxicity.

  • Provide well-drained soil to prevent root rot.
  • Ensure at least 6-8 hours of direct sunlight daily.
  • Monitor for pests like aphids and spider mites.
  • Harvest licorice roots in the fall after 3-4 years of growth.
  • Be mindful of its potential for rhizomatous spread and contain it if necessary.
❄️ Winter: In winter, reduce watering significantly as the plant enters dormancy. Protect outdoor plants from frost by mulching around the base. If grown in containers, move them to a sheltered location.
☀️ Summer: During the summer, ensure the plant receives adequate sunlight and water regularly, especially during hot and dry periods. Monitor for pests and diseases, and provide fertilizer as needed.

Nasturtium Care Tips

Nasturtiums are best grown outdoors due to their need for full sun. Indoor cultivation is challenging and requires very bright light and careful watering. They are prone to pests and diseases, and their sprawling growth habit can be difficult to manage in a container.

  • Soak seeds overnight before planting to improve germination.
  • Avoid over-fertilizing, as it can lead to excessive foliage growth and fewer flowers.
  • Pinch back stems regularly to encourage bushier growth.
  • Water deeply but infrequently, allowing the soil to dry slightly between waterings.
  • Monitor for pests like aphids and whiteflies and treat promptly.
❄️ Winter: Nasturtiums are annuals and will die back in winter. Remove dead foliage and discard the plants.
☀️ Summer: Provide regular watering and fertilization during the summer growing season. Monitor for pests and diseases and treat promptly. Pinch back stems to encourage bushier growth and more flowers.

❓ 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.

Nasturtium

What are the light requirements for Nasturtium?

Nasturtiums thrive best in full sun, requiring at least 6 hours of direct sunlight each day for abundant flowering. While they can tolerate partial shade, reduced sunlight can lead to fewer blooms and leggy growth. In hotter climates, providing some afternoon shade can prevent leaf scorch.

How do I care for Nasturtium?

Nasturtiums are relatively easy to care for, making them a great choice for beginner gardeners. They thrive in full sun to partial shade, requiring at least 6 hours of sunlight per day for optimal blooming. Water regularly, allowing the soil to dry slightly between waterings; avoid overwatering, which can lead to root rot.

How do I propagate Nasturtium?

Nasturtiums are easily propagated from seeds or stem cuttings. To propagate from seeds, sow seeds directly into the garden or containers in spring after the last frost. Alternatively, start seeds indoors 4-6 weeks before the last frost. Soak seeds in water overnight to improve germination.
