Medlar vs Pencil Cactus Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Medlar
Mespilus germanica
The Medlar is a deciduous tree or large shrub, typically reaching 3-6 meters (10-20 feet) in height. It's known for its unusual fruit, which is hard and unpalatable when freshly picked, requiring 'bletting' (a period of softening and slight decay) to become edible. It has attractive white flowers in late spring and develops interesting gnarled branches as it matures. The leaves turn reddish-brown in the fall, adding to its ornamental value. It is primarily grown outdoors for its fruit and ornamental qualities. It is not suitable for indoor cultivation due to its size and need for specific environmental conditions.
Pencil Cactus
Euphorbia tirucalli
Euphorbia tirucalli, commonly known as Pencil Cactus, is a succulent shrub or small tree characterized by its smooth, cylindrical, pencil-thick green branches. It is virtually leafless for most of the year, with small, inconspicuous leaves appearing only briefly during the growing season. This plant can reach significant heights outdoors, but remains smaller when grown in containers. It's popular for its unique architectural form and drought tolerance. People grow it for its sculptural qualities and low maintenance requirements. It is primarily an outdoor plant but can be grown indoors with proper care.

💡 Pro Tips For Comparing These Plants
Medlar Care Tips
Medlar is an outdoor tree that is not suitable for indoor growing. It requires full sun, well-draining soil, and specific pruning to maintain its shape and fruit production. Indoor cultivation is extremely challenging due to space requirements, light needs, and dormancy requirements.
- Ensure good drainage to prevent root rot.
- Prune regularly to maintain shape and fruit production.
- Protect young trees from frost.
- Fertilize in early spring with a balanced fertilizer.
- Monitor for pests and diseases and treat promptly.
Pencil Cactus Care Tips
Pencil Cactus requires bright light and infrequent watering. It is relatively easy to care for, but its toxic sap makes it unsuitable for homes with pets or small children. Indoor growth requires careful attention to light and watering to prevent etiolation and root rot.
- Provide at least 6 hours of direct sunlight daily.
- Allow the soil to dry out completely between waterings.
- Use a well-draining succulent mix to prevent root rot.
- Wear gloves and eye protection when handling the plant to avoid contact with the toxic sap.
- Avoid over-fertilizing, as this can lead to leggy growth.

❓ Frequently Asked Questions — Comparing These Plants
Medlar
What are the light requirements for Medlar?
Medlar thrives in bright, indirect sunlight when grown indoors. Insufficient light can lead to leggy growth and reduced flowering and fruiting. A south-facing or east-facing window is ideal. If natural light is limited, supplement with a grow light. Rotate the plant regularly to ensure even light exposure on all sides.
How do I care for Medlar?
Caring for Medlar as an indoor tree requires attention to several key factors. Ensure it receives bright, indirect sunlight. Water thoroughly when the top inch of soil is dry, allowing excess water to drain. Maintain moderate humidity levels. Use a well-draining potting mix. Fertilize sparingly during the growing season (spring and summer) with a balanced liquid fertilizer.
How do I propagate Medlar?
Medlar can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from new growth in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix. Keep the soil moist and provide high humidity. Roots should develop in 4-8 weeks.
Pencil Cactus
What are the light requirements for Pencil Cactus?
Pencil Cactus thrives in bright, direct sunlight. Aim for at least 6 hours of direct sunlight per day. Insufficient light can cause etiolation, resulting in weak, pale growth. An east- or south-facing window is ideal. If natural light is limited, supplement with a grow light. Rotate the plant regularly to ensure even light exposure on all sides.
How do I care for Pencil Cactus?
Pencil Cactus is a relatively easy-to-care-for succulent, thriving on neglect and bright light. Plant in well-draining cactus mix. Water sparingly, allowing the soil to dry out completely between waterings, especially during winter dormancy. Provide at least 6 hours of direct sunlight daily.
How do I propagate Pencil Cactus?
Pencil Cactus can be easily propagated through stem cuttings. Allow the cut end to callus over for several days before planting in well-draining cactus mix. Keep the soil slightly moist until roots develop. Propagation from offsets is also possible; simply detach the offset and plant it in well-draining soil. Seed propagation is more challenging and requires patience. Grafting is less common but can be used to propagate difficult-to-root varieties. Always wear gloves when handling cuttings due to the irritating sap. Allow the cutting to dry and form a callous before planting in soil. Protect from excessive sun while rooting. Rooting hormone can be used, but is not necessary.
