Ornamental Kale vs Ornamental Plum Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Ornamental Kale
Brassica oleracea var. acephala
Ornamental kale is a cool-season biennial grown as an annual for its colorful foliage. It is not grown for consumption, though technically edible. The plant forms a rosette of broad, ruffled or frilled leaves in shades of green, purple, pink, red, and white. The vibrant colors intensify in cooler temperatures. It is primarily an outdoor plant, thriving in full sun and cool weather. People grow it for its decorative appeal in gardens, containers, and borders, providing color and texture in the fall and winter months.
Ornamental Plum
Prunus cerasifera
The ornamental plum (Prunus cerasifera) is a deciduous tree known for its profuse display of pink or white flowers in early spring, followed by attractive purple or bronze-colored foliage. It typically grows to a height of 15-25 feet. While primarily an outdoor tree, it's sometimes forced into bloom indoors, but it's not naturally suited for indoor life. People grow it for its ornamental value, adding color and visual interest to landscapes, especially in early spring when other trees are still dormant. It's a popular choice for street trees and garden focal points.

💧 Watering Needs
Ornamental Kale
Water regularly, keeping the soil consistently moist but not waterlogged. Check the soil moisture by sticking your finger about an inch deep. If it feels dry, water thoroughly until water drains from the bottom of the pot. Overwatering can lead to root rot, indicated by yellowing and wilting leaves. Underwatering will cause the leaves to droop and become crispy.
Ornamental Plum
Water deeply when planting and during dry spells, especially in the first few years. Established trees are relatively drought-tolerant. Overwatering can lead to root rot, indicated by yellowing leaves and a general decline in health. Underwatering will cause leaf drop and stunted growth.

❓ Frequently Asked Questions — Comparing These Plants
Ornamental Kale
What are the light requirements for Ornamental Kale?
Ornamental Kale needs at least 6 hours of direct sunlight per day to develop its best color. Insufficient light can result in leggy growth and dull foliage. When planting, choose a location that receives full sun, especially during the cooler months. In warmer climates, providing some afternoon shade can prevent the leaves from scorching. For container-grown Ornamental Kale, rotate the pot regularly to ensure even light exposure. If growing indoors, supplement with grow lights to provide adequate illumination. East-facing windows are generally suitable, but south-facing windows may require shading during the hottest part of the day.
How do I care for Ornamental Kale?
Ornamental Kale thrives in cool weather and prefers full sun to partial shade. Plant it in well-draining soil that is rich in organic matter. Water regularly, especially during dry spells, but avoid overwatering, which can lead to root rot. Fertilize every 2-3 weeks with a balanced fertilizer during the growing season to promote vibrant colors. Deadhead any yellowing or damaged leaves to maintain its appearance. Protect from pests such as aphids and cabbage worms. Ensure good air circulation to prevent fungal diseases. Monitor for signs of disease or pest infestation and treat promptly. Provide support if the plant becomes top-heavy. Adjust watering and fertilization based on weather conditions.
How do I propagate Ornamental Kale?
Ornamental Kale is typically grown from seed, but it can also be propagated through stem cuttings, although this is less common. To propagate from stem cuttings, take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the soil moist and provide indirect light until roots develop.
Ornamental Plum
What are the light requirements for Ornamental Plum?
Ornamental Plums require bright, indirect light to thrive indoors. Direct sunlight can scorch their leaves, while insufficient light can lead to leggy growth and faded foliage color. A location near an east- or west-facing window is ideal. If you only have a south-facing window, filter the light with a sheer curtain. Rotate the plant regularly to ensure all sides receive adequate light. If natural light is limited, supplement with a grow light. Observe the plant’s leaves; if they start to lose their vibrant color, it may indicate insufficient light. Adjust the plant’s location accordingly to maximize light exposure without causing leaf burn.
How do I care for Ornamental Plum?
Ornamental Plums thrive indoors with bright, indirect light. Water when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain moderate humidity levels, especially during winter months. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain shape and size, removing any dead or crossing branches. Repot every 2-3 years, or when the plant becomes root-bound, using a well-draining potting mix. Monitor for pests like spider mites and aphids, treating promptly with insecticidal soap. Provide stable temperatures between 60-75°F (15-24°C) and avoid drafts. Rotate the plant periodically for even growth. Ensure adequate airflow around the plant.
How do I propagate Ornamental Plum?
Ornamental Plums can be propagated via 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 and keep it moist. Cover with a plastic bag to maintain humidity. Roots should develop in 4-6 weeks. For air layering, make a small incision on a stem and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Keep the moss moist. Roots should develop in several weeks. Once rooted, cut the stem below the roots and pot it in a new container. Both methods require patience and consistent moisture.
