Flax Lily vs Hawthorn Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Flax Lily
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.
Hawthorn
Crataegus spp.
Hawthorns are deciduous shrubs or small trees, typically reaching heights of 5-15 meters. They are characterized by their thorny branches, simple leaves, and clusters of white, pink, or red flowers in spring. These flowers give way to small, apple-like fruits called haws in the fall. Hawthorns are primarily outdoor plants, valued for their ornamental appeal, wildlife value (providing food and shelter), and traditional medicinal uses. Growing them indoors is extremely challenging due to their need for full sun and dormancy period.

💡 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.
Hawthorn Care Tips
Hawthorns are primarily outdoor plants and are not suitable for indoor growing. They require full sun, well-draining soil, and a period of winter dormancy. Indoor cultivation is extremely challenging and not recommended.
- Plant in well-draining soil to prevent root rot.
- Provide full sun for optimal flowering and fruiting.
- Prune annually to maintain shape and remove dead wood.
- Monitor for pests and diseases and treat promptly.
- Protect young trees from deer browsing.

❓ 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.
Hawthorn
What are the light requirements for Hawthorn?
Hawthorn trees thrive in bright, indirect sunlight. While they can tolerate some direct sunlight, especially in the morning or late afternoon, prolonged exposure to intense direct sun can scorch their leaves. An east-facing window is often ideal, providing gentle morning light. A south-facing window can also work, but be sure to filter the light with a sheer curtain. If your Hawthorn is not receiving enough light, it may exhibit leggy growth or produce fewer flowers. Rotate the plant regularly to ensure even light exposure on all sides. If natural light is insufficient, consider supplementing with grow lights. Keep the light source 6-12 inches away from the plant for best results.
How do I care for Hawthorn?
Hawthorn trees, when grown indoors, require specific care to thrive. Place your Hawthorn in a location that receives bright, indirect sunlight. Direct sunlight can scorch the leaves, especially during the hottest part of the day. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Use a well-draining potting mix formulated for bonsai or trees. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain the desired shape and remove any dead or crossing branches. Repot every 2-3 years, or when the plant becomes root-bound, using a slightly larger pot. Monitor for pests such as aphids or spider mites and treat promptly with insecticidal soap. Maintain moderate humidity levels, especially during the winter months when indoor air tends to be drier.
How do I propagate Hawthorn?
Hawthorn trees can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy branch in the spring. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist. Cover with a plastic bag to increase humidity. Roots should develop in 4-6 weeks. For air layering, select a healthy branch and make a shallow cut in the bark. Wrap the cut with moist sphagnum moss and cover with plastic wrap. Secure the plastic wrap with tape or twine. Keep the moss moist. Roots should develop in several weeks. Once roots are visible, cut the branch below the roots and pot it in a well-draining potting mix.
