Asarum vs Lion's Ear Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Asarum
Asarum canadense
Asarum canadense, or Canadian Wild Ginger, is a rhizomatous herbaceous perennial typically found in moist, deciduous woodlands. It's known for its kidney-shaped to heart-shaped, velvety green leaves that grow in pairs from creeping rhizomes. The plant produces a single, bell-shaped, brownish-purple flower near the ground in spring, often hidden beneath the foliage. While called 'ginger', it's not related to culinary ginger and should not be consumed as a substitute. It is primarily grown as a groundcover in shaded gardens for its attractive foliage and ability to suppress weeds. It is NOT suited for indoor growing.
Lion's Ear
Leonotis leonurus
Leonotis leonurus, commonly known as Lion's Ear, is a large, robust shrub native to Southern Africa. It typically grows to a height of 3-6 feet. It features distinctive, tiered whorls of bright orange, tubular flowers that resemble a lion's ear, hence the name. The plant has lance-shaped, aromatic leaves. While it can be grown in containers, it is primarily an outdoor plant, thriving in sunny gardens. People grow it for its unique and showy flowers, its drought tolerance, and its traditional medicinal uses.

💡 Pro Tips For Comparing These Plants
Asarum Care Tips
Asarum canadense is primarily an outdoor plant and is very difficult to grow indoors. It requires specific shade and moisture conditions that are hard to replicate indoors. It also spreads via rhizomes, which would quickly outgrow a container. Toxicity to pets is a major concern.
- Ensure excellent drainage to prevent root rot
- Provide consistent moisture, especially during dry periods
- Apply a layer of mulch to retain moisture and suppress weeds
- Divide rhizomes every few years to prevent overcrowding
- Monitor for slugs and snails and take appropriate action
Lion's Ear Care Tips
Lion's Ear is primarily an outdoor plant and requires full sun to thrive. Growing it indoors is challenging due to its high light requirements. It needs well-draining soil and regular watering, but is relatively drought-tolerant once established. Due to its toxicity to pets, it's best to avoid growing it if you have animals that may ingest it.
- Provide at least 6 hours of direct sunlight daily for optimal flowering.
- Water deeply but infrequently, allowing the soil to dry out between waterings.
- Prune after flowering to encourage bushier growth and more blooms.
- Protect from frost in colder climates by mulching or moving indoors (if in a container).
- Monitor for pests like aphids and spider mites and treat promptly.

❓ Frequently Asked Questions — Comparing These Plants
Asarum
What are the light requirements for Asarum?
Asarum requires shade to partial shade. Direct sunlight can scorch its delicate leaves, leading to browning and stunted growth. Ideal placement is under the canopy of trees or on the north side of a building, where it receives filtered sunlight or dappled shade. Avoid locations that receive intense afternoon sun. If growing Asarum indoors, place it near a north-facing window or use sheer curtains to diffuse the light. Insufficient light can result in leggy growth and reduced flowering. Observe the plant’s foliage for signs of stress, such as pale or yellowing leaves, and adjust the light accordingly. Remember that the intensity of light changes throughout the year, so monitor your Asarum’s light exposure and adjust its placement as needed.
How do I care for Asarum?
Asarum thrives in shady locations with well-draining, humus-rich soil. Water regularly, especially during dry periods, keeping the soil consistently moist but not waterlogged. Fertilize sparingly in early spring with a balanced, slow-release fertilizer to encourage healthy growth and blooming. Avoid direct sunlight, which can scorch the leaves. Mulch around the plants to retain moisture and suppress weeds. Prune away any dead or damaged foliage to maintain appearance and prevent disease. Asarum prefers cool temperatures and high humidity. Provide good air circulation to prevent fungal diseases. Repot container-grown plants every few years in spring. Monitor for pests such as slugs and snails and treat accordingly. With proper care, Asarum will reward you with its beautiful foliage and unique flowers.
How do I propagate Asarum?
Asarum is best propagated by division in early spring or fall. Carefully dig up the plant and divide the rhizomes into sections, ensuring each section has roots and foliage. Replant the divisions in well-draining, humus-rich soil. Keep the soil consistently moist until the plants are established. Stem cuttings are not a reliable method for Asarum propagation. Keiki, or plantlets, do not naturally form on Asarum. Division is the most successful method for propagating this plant. Ensure the divisions are planted at the same depth as the original plant. Mulch around the newly planted divisions to retain moisture and suppress weeds. Water thoroughly after planting.
Lion's Ear
What are the light requirements for Lion's Ear?
Lion’s Ear requires abundant sunlight to thrive and produce its vibrant blooms. Aim for at least six hours of direct sunlight per day. Indoors, place the plant near a south-facing window where it can receive maximum light exposure. If natural light is insufficient, supplement with grow lights. Insufficient light can result in leggy growth and reduced flowering. Rotate the plant regularly to ensure even light exposure on all sides. During the winter months, when sunlight is limited, consider using grow lights to maintain adequate light levels. Bright, indirect light is acceptable, but direct sunlight is preferred for optimal growth and flowering. Monitor the plant for signs of light stress, such as scorched leaves, and adjust placement accordingly.
How do I care for Lion's Ear?
Lion’s Ear thrives in well-draining soil and requires regular watering, especially during the growing season. Allow the top inch of soil to dry out before watering again. Provide ample sunlight, ideally at least six hours per day, for optimal flowering. Fertilize regularly with a balanced fertilizer during the growing season to encourage abundant blooms. Prune regularly to maintain shape and remove spent flowers. Protect from frost, as it is not cold-hardy. Ensure good air circulation to prevent fungal diseases. Repot annually in spring to refresh the soil. Monitor for pests and diseases, and treat promptly if necessary. Propagation is easily done through stem cuttings or seeds. Provide support if the plant becomes top-heavy. Ensure the plant has sufficient space to grow. Avoid overwatering, which can lead to root rot.
How do I propagate Lion's Ear?
Lion’s Ear can be propagated through stem cuttings, division, and seeds. For stem cuttings, take a 4-6 inch cutting from a healthy stem, remove the lower leaves, and dip the cut end in rooting hormone. Plant the cutting in moist, well-draining soil. Keep the soil consistently moist and provide bright, indirect light. For division, carefully separate the root ball of a mature plant into smaller sections, ensuring each section has healthy roots and stems. Replant each section in its own pot. Seed propagation involves sowing seeds in well-draining soil and keeping them moist until germination. Provide adequate warmth and light for successful germination. Propagation is best done in spring or early summer.
