It is descended from the wild cabbage, Brassica oleracea, and is closely related to broccoli, cauliflower, and Brussels sprouts. The plant typically reaches a height and spread of 1 to 2 feet. Cabbage is primarily an outdoor crop, grown for its edible leaves, which can be eaten raw, cooked, or fermented. People grow it for culinary purposes and its nutritional value.
Crown of Thorns
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 is a popular ornamental plant grown for its drought tolerance and long-lasting blooms. It typically grows as a sprawling shrub, reaching up to 1-2 meters in height. While it can be grown indoors, it thrives best with ample sunlight, often making it more suitable as an outdoor plant in warmer climates. People grow it for its unique appearance and relatively easy care.

💡 Pro Tips For Comparing These Plants
Cabbage Care Tips
Cabbage is primarily an outdoor plant and requires full sun and consistent moisture. Growing it indoors is challenging due to the high light requirements and space needed for proper head development. It is difficult to replicate outdoor growing conditions indoors.
- Provide consistent moisture, especially during head formation.
- Fertilize regularly with a balanced fertilizer.
- Protect from pests with appropriate treatments.
- Ensure good soil drainage to prevent root rot.
- Harvest when the head is firm and fully developed.
Crown of Thorns Care Tips
Crown of Thorns requires bright sunlight and well-draining soil. Overwatering is a common issue. It can be grown indoors with sufficient light, but may not flower as profusely as when grown outdoors. Toxicity to pets is a significant concern.
- Provide at least 4-6 hours of direct sunlight daily for optimal growth and flowering.
- Allow the soil to dry out completely between waterings to prevent root rot.
- Use a well-draining succulent or cactus mix to ensure proper drainage.
- Fertilize sparingly during the growing season with a balanced liquid fertilizer.
- Wear gloves when pruning or handling the plant to avoid skin irritation from the sap.

❓ Frequently Asked Questions — Comparing These Plants
Cabbage
What are the light requirements for Cabbage?
Flowering cabbage thrives in full sun, requiring at least six hours of direct sunlight per day to develop its most vibrant colors. While it can tolerate partial shade, the colors may be less intense. When planting in a container, choose a location that receives ample sunlight throughout the day. If growing indoors, place the plant near a sunny window. Rotate the plant regularly to ensure even light exposure and prevent it from leaning towards the light source. Insufficient light can lead to leggy growth and dull colors. If natural light is limited, consider supplementing with artificial grow lights. During the shorter days of fall and winter, supplemental lighting can help maintain the plant’s health and appearance.
How do I care for Cabbage?
Flowering cabbage requires well-draining soil and prefers full sun to partial shade, although full sun will result in the best color development. Water regularly, keeping the soil consistently moist but not waterlogged. Fertilize every 2-3 weeks with a balanced fertilizer during the growing season to encourage vibrant colors and healthy growth. Remove any yellowing or damaged leaves to maintain the plant’s appearance and prevent disease. Protect from extreme cold temperatures if possible, as prolonged freezing can damage the foliage. Plant in a location with good air circulation to prevent fungal diseases. Monitor for pests such as aphids and cabbage worms, and treat as needed. Regular deadheading is not required as flowering cabbage is grown for its foliage, not flowers. Ensure adequate spacing between plants to allow for proper air circulation and growth. Provide support if necessary, especially for taller varieties.
How do I propagate Cabbage?
Flowering cabbage is typically grown from seed, but propagation through stem cuttings is possible, although less common. Take stem cuttings from healthy, non-flowering shoots. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining rooting medium. Keep the medium consistently moist and provide adequate light. Rooting should occur within a few weeks. Division is not a practical method for flowering cabbage, and keikis do not form. Propagation from seed is the most reliable method. Collect seeds from mature plants and store them in a cool, dry place until planting.
Crown of Thorns
What are the light requirements for Crown of Thorns?
Crown of Thorns requires bright, direct sunlight to thrive. Ideally, place it in a south-facing window where it can receive at least 4-6 hours of sunlight per day. Insufficient light can lead to leggy growth, reduced flowering, and a loss of vibrancy in the bracts. If you don’t have a sufficiently sunny window, consider supplementing with a grow light. Rotate the plant regularly to ensure even light exposure on all sides. During the summer months, you can move your Crown of Thorns outdoors to a sunny location, but be sure to acclimate it gradually to avoid sunburn. The plant’s ability to flower profusely depends on adequate light.
How do I care for Crown of Thorns?
Crown of Thorns thrives on neglect, making it an easy-care succulent. Plant it in well-draining soil, such as a cactus mix, to prevent root rot. Provide it with bright, direct sunlight for at least 4-6 hours daily. Water sparingly, allowing the soil to dry completely between waterings. Reduce watering frequency during the dormant winter months. Fertilize lightly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Maintain a room temperature between 65-75°F (18-24°C). Avoid overwatering, as this is the most common cause of problems. Repot every 2-3 years, or when the plant becomes root-bound. Prune to maintain shape and remove dead or damaged stems. Be cautious of the milky sap, which can be irritating to the skin and eyes.
How do I propagate Crown of Thorns?
Crown of Thorns can be propagated through stem cuttings. Allow the cut end to callous over for several days before planting in well-draining soil. Keep the soil slightly moist until roots develop. Leaf cuttings are not generally successful. Offsets, or small plantlets that grow at the base of the plant, can be carefully separated and potted individually. Wear gloves to protect your skin from the irritating sap. Rooting hormone can improve the success rate of stem cuttings. Provide bright, indirect light during the rooting process. Avoid overwatering, as this can lead to rot. Propagation is best done during the growing season (spring and summer).
