Euphorbia vs Hazel Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Euphorbia
Euphorbia milii
Euphorbia milii, commonly known as Crown of Thorns, is a succulent shrub characterized by its thorny stems and vibrant bracts surrounding small, inconspicuous flowers. Native to Madagascar, it's a popular ornamental plant grown for its drought tolerance and long-lasting blooms. The plant features grey-brown thorny stems and oval-shaped green leaves that are often deciduous. While it can be grown indoors, it thrives best with ample sunlight, making it more suitable for outdoor environments in warmer climates. People grow it for its unique appearance and relatively easy care.
Hazel
Corylus avellana
Corylus avellana, or Hazel, is a deciduous shrub or small tree typically reaching 3-8 meters (10-26 feet) in height. It features multiple stems and a rounded crown. The bark is smooth and grayish-brown when young, becoming slightly fissured with age. Hazelnuts are primarily grown outdoors for their edible nuts and ornamental value. They are not naturally suited for indoor environments due to their size, light requirements, and need for seasonal dormancy. People grow them for nut production, wildlife attraction, and as a landscape feature.

💧 Watering Needs
Euphorbia
Allow the soil to dry out completely between waterings. Overwatering can lead to root rot. Water thoroughly when the soil is dry to the touch. Signs of overwatering include yellowing leaves and a mushy stem. Underwatering is indicated by shriveled leaves and stunted growth.
Hazel
Water deeply when planting and during dry periods, especially when young. Established trees are relatively drought-tolerant. Overwatering can lead to root rot, so ensure well-draining soil. Check soil moisture before watering.

💡 Pro Tips For Comparing These Plants
Euphorbia Care Tips
Crown of Thorns requires bright sunlight and well-draining soil. It's relatively drought-tolerant but susceptible to root rot if overwatered. Handle with care due to the thorns and toxic sap. Indoor flowering may be less prolific than outdoors.
- Provide at least 4-6 hours of direct sunlight daily for optimal flowering.
- Allow the soil to dry out completely between waterings to prevent root rot.
- Wear gloves when handling the plant to avoid skin irritation from the sap.
- Fertilize sparingly during the growing season with a balanced liquid fertilizer.
- Prune regularly to maintain shape and remove dead or damaged stems.
Hazel Care Tips
Hazel is an outdoor plant that is not suitable for indoor growing. It requires full sun, well-draining soil, and seasonal dormancy. Indoor attempts will likely fail due to insufficient light, space, and the inability to replicate natural seasonal cycles.
- Choose disease-resistant varieties to minimize problems.
- Provide adequate water during the first few years to establish a strong root system.
- Protect young trees from deer and other herbivores.
- Prune regularly to maintain shape and promote nut production.

❓ Frequently Asked Questions — Comparing These Plants
Euphorbia
What are the light requirements for Euphorbia?
Euphorbias need bright, indirect sunlight for optimal growth. Insufficient light can lead to etiolation (stretching) and weak growth. South- or west-facing windows are ideal, but be cautious of intense afternoon sun, which can scorch the plant. If natural light is limited, supplement with a grow light. Rotate the plant regularly to ensure even growth on all sides. A minimum of 6 hours of bright light daily is recommended. Observe the plant for signs of light stress, such as pale coloration or elongated stems, and adjust its position accordingly.
How do I care for Euphorbia?
Euphorbias, as succulents, thrive in bright light and well-draining soil. Water thoroughly only when the soil is completely dry to the touch, typically every 2-4 weeks, depending on the environment. Ensure the pot has drainage holes to prevent root rot. During the growing season (spring and summer), fertilize sparingly with a balanced, diluted succulent fertilizer. Reduce watering significantly in the fall and winter during their dormant period. Provide good air circulation to prevent fungal diseases. Repot every 2-3 years or when the plant becomes root-bound. Handle with care, as the milky sap is toxic and can cause skin irritation. Protect from frost and temperatures below 50°F (10°C).
How do I propagate Euphorbia?
Euphorbias can be propagated through leaf cuttings, offsets, or stem cuttings. For stem cuttings, allow the cut end to callous over for several days before planting in well-draining soil. For leaf cuttings, place the leaf on top of the soil and wait for roots to develop. Offsets can be carefully separated from the parent plant and planted individually. Always wear gloves and eye protection when handling Euphorbia sap, as it can cause skin irritation. Keep the cuttings in a warm, bright location and water sparingly until roots have formed. Propagation is best done during the growing season (spring or summer).
Hazel
What are the light requirements for Hazel?
Hazel trees thrive in bright, indirect light. Avoid placing them in direct sunlight, especially during the hottest parts of the day, as this can cause leaf scorch. An east-facing window is often ideal, providing gentle morning light. A north-facing window can also work if the light is bright enough. If you notice the leaves becoming pale or yellowing, it may indicate that the plant is receiving too much light. Conversely, if the plant is not growing well or the leaves are small and sparse, it may not be getting enough light. Supplementing with a grow light can be beneficial, especially during the winter months.
How do I care for Hazel?
Providing the right care is essential for a thriving indoor Hazel. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Place your Hazel in a location with bright, indirect light. Avoid direct sunlight, which can scorch the leaves. Maintain a moderate humidity level, especially during dry winter months, by misting regularly or using a humidifier. Fertilize sparingly, only during the growing season (spring and summer), with a balanced liquid fertilizer diluted to half strength. Repot your Hazel every 2-3 years, or when it becomes root-bound, into a slightly larger pot with well-draining potting mix. Prune regularly to maintain its shape and remove any dead or damaged branches. Consistent care and stable conditions are key to a happy and healthy indoor Hazel.
How do I propagate Hazel?
Hazels can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from new growth in spring or early summer. 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 in a humid environment. For air layering, select a healthy stem and make a small incision. Wrap the incision with moist sphagnum moss and cover it with plastic wrap. Secure the plastic wrap with tape and check the moisture level regularly. Once roots have formed, cut the stem below the roots and plant it in a pot. Both methods require patience and consistent moisture to be successful.
