Euphorbia polychroma

Cushion Spurge is a mounded, herbaceous perennial prized for its vibrant spring foliage and long-lasting floral display. It forms a dense, cushion-like shape, typically reaching 1-3 feet in height and spread. The plant features bright green leaves that turn brilliant shades of yellow, orange, and red in the fall. While it produces small, inconspicuous flowers, the colorful bracts (modified leaves) surrounding the flowers are the main attraction, providing weeks of vibrant color. It is primarily an outdoor plant, grown in gardens and borders for its ornamental value and drought tolerance. It is not suited for indoor growing.

Licorice Plant

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.

⚡ Key Differences Between These Plants

☀️

Cushion Spurge needs full sun to partial shade, while Licorice Plant prefers full sun (at least 6-8 hours of direct sunlight daily).

💡 Pro Tips For Comparing These Plants

Cushion Spurge Care Tips

Cushion Spurge is an outdoor perennial that requires full sun and well-draining soil. It is not suitable for indoor growing due to its high light requirements and need for a cold dormancy period. Indoor attempts will likely result in weak growth and failure to thrive.

  • Plant in well-draining soil to prevent root rot.
  • Provide full sun for best foliage color.
  • Water deeply but infrequently, allowing the soil to dry out between waterings.
  • Apply a balanced fertilizer in early spring.
  • Wear gloves when handling the plant to avoid skin irritation from the sap.
❄️ Winter: The plant goes dormant in winter and requires little care. Cut back dead foliage in early spring.
☀️ Summer: Water during dry spells. Provide afternoon shade in hot climates to prevent leaf scorch.

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.

❓ Frequently Asked Questions — Comparing These Plants

Cushion Spurge

What are the light requirements for Cushion Spurge?

Cushion Spurge thrives in bright, direct sunlight. Ideally, it should receive at least six hours of direct sunlight per day. Insufficient light can lead to etiolation, where the plant stretches and becomes leggy in search of light.

How do I care for Cushion Spurge?

Cushion Spurge requires well-draining soil, such as a cactus mix, and bright, direct sunlight for at least six hours per day. Water thoroughly only when the soil is completely dry, typically every 2-4 weeks, depending on the environment and season. Avoid overwatering, as this can lead to root rot.

How do I propagate Cushion Spurge?

Cushion Spurge can be propagated through several methods:

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.
