Dianella tasmanica

Dianella tasmanica, commonly known as the Flax Lily, is a rhizomatous perennial herb native to Tasmania. It features strappy, arching leaves that resemble flax, hence the name. It typically grows outdoors in shaded or partially shaded areas. While it can be grown indoors, it requires specific conditions to thrive and may not flower as readily as when grown outdoors. People grow it for its attractive foliage, clumping habit, and relatively low maintenance when grown in suitable conditions.

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.

💡 Pro Tips For Comparing These Plants

Flax Lily Care Tips

Flax Lily is relatively easy to care for, but requires bright, indirect light and well-draining soil. Overwatering is a common problem. It may not flower indoors as readily as outdoors. It spreads via rhizomes, so repotting may be needed more frequently than other houseplants.

  • Allow the top inch of soil to dry out before watering.
  • Provide bright, indirect light to maintain vibrant foliage.
  • Fertilize sparingly during the growing season.
  • Monitor for pests like spider mites and treat promptly.
  • Repot every 1-2 years to prevent root-bound conditions.
❄️ Winter: Reduce watering frequency during winter as growth slows down. Ensure the plant still receives adequate light. Avoid placing it near cold drafts.
☀️ Summer: Provide adequate moisture during the warmer months. Protect from intense direct sunlight to prevent leaf burn. Increase humidity if possible.

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

Flax Lily

What are the light requirements for Flax Lily?

Flax Lily flourishes in bright, indirect light. Direct sunlight can scorch its leaves, so avoid placing it in south-facing windows without some form of shading. An east or west-facing window is ideal, where it can receive gentle morning or afternoon light. If your plant is in a lower-light environment, its growth may be slower, and the colors may appear less vibrant. Rotate your plant regularly to ensure even light exposure on all sides. Insufficient light can lead to leggy growth and faded foliage.

How do I care for Flax Lily?

Flax Lily thrives in bright, indirect light but can tolerate lower light conditions. Water when the top inch of soil feels dry, ensuring the pot has good drainage to prevent root rot. Maintain moderate humidity levels, especially during dry seasons, by misting the plant regularly or using a humidifier. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Repot every 1-2 years, or when the plant becomes root-bound, using a well-draining potting mix. Prune away any dead or yellowing leaves to maintain its appearance and health. Protect from frost and extreme temperatures. Proper watering, light, and humidity are key to a thriving Flax Lily.

How do I propagate Flax Lily?

Flax Lily can be propagated through division, stem cuttings, and air layering.

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.
