Flowering Kale vs Norway Maple Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Flowering Kale
Brassica oleracea var. acephala
Flowering kale is a cool-season biennial grown as an annual for its vibrant, colorful foliage. It is not grown for edible leaves like its close relative, edible kale. The plant forms a rosette of ruffled or frilly leaves in shades of white, pink, purple, or red, surrounded by outer green leaves. It is primarily an outdoor plant, thriving in cooler temperatures and full sun. People grow it for its ornamental value, adding color and texture to gardens and containers during the fall and winter months.
Norway Maple
Acer platanoides
The Norway Maple is a deciduous tree typically reaching heights of 20-30 meters (65-100 feet). It has a rounded crown and smooth gray bark that becomes furrowed with age. The leaves are palmate, with 5-7 lobes, and typically turn yellow in the fall, though some cultivars display orange or red hues. It's primarily an outdoor tree, valued for its shade, ornamental qualities, and adaptability to various soil conditions. It is not naturally an indoor plant and will not thrive indoors.

❓ Frequently Asked Questions — Comparing These Plants
Flowering Kale
What are the light requirements for Flowering Kale?
Flowering Kale needs at least six hours of direct sunlight per day to develop its best color. Insufficient light can lead to leggy growth and dull coloration. When planting, choose a location that receives full sun exposure. If growing in containers, rotate the plants regularly to ensure even light exposure on all sides.
How do I care for Flowering Kale?
Flowering Kale thrives in cool temperatures (40-70°F) and requires at least 6 hours of sunlight daily. Plant in well-draining soil, enriched with compost or other organic matter. Water regularly, keeping the soil consistently moist but not waterlogged. Fertilize every 2-3 weeks with a balanced fertilizer during the growing season to promote vibrant color.
How do I propagate Flowering Kale?
Flowering Kale is primarily grown from seed, but propagation through stem cuttings is possible, though less common. Take stem cuttings from healthy, non-flowering shoots in late summer or early fall. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the cuttings moist and in a warm, humid environment until roots develop.
Norway Maple
What are the light requirements for Norway Maple?
Norway Maples grown indoors need bright, indirect light to flourish. Direct sunlight can scorch their leaves, especially during the hottest parts of the day. An east-facing window that receives morning sun or a west-facing window with filtered afternoon light is ideal. If you don’t have access to sufficient natural light, supplement with grow lights. Insufficient light can lead to leggy growth and a lack of vibrant leaf color. Rotate your plant regularly to ensure all sides receive adequate light exposure, promoting even growth.
How do I care for Norway Maple?
The Norway Maple, when grown indoors, requires specific care to thrive. Place it in a location with bright, indirect sunlight. Water thoroughly when the top inch of soil is dry, ensuring proper drainage to prevent root rot. Maintain moderate humidity levels, especially during dry winter months, by misting the leaves or using a humidifier. Use a well-draining potting mix and 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 diseased branches. Repot every 2-3 years into a slightly larger pot to accommodate root growth. Maintain stable temperatures between 60-75°F (15-24°C) and protect from drafts. Rotate the plant periodically to ensure even growth on all sides.
How do I propagate Norway Maple?
Norway Maples can be propagated through stem cuttings or air layering.
