Kale (Ornamental) vs Stokesia Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Kale (Ornamental)
Brassica oleracea var. sabellica
Ornamental kale is a cool-season biennial grown as an annual for its vibrant, colorful foliage. It is not grown for consumption, though it is related to edible kale. The plant forms a rosette of frilly or ruffled leaves in shades of white, pink, purple, and red. Ornamental kale is primarily an outdoor plant, thriving in cooler temperatures and full sun. It is often used in fall and winter gardens for its striking visual appeal, providing color when many other plants are dormant. While technically possible to grow indoors, it is challenging to provide the necessary light and temperature conditions for optimal growth.
Stokesia
Stokesia laevis
Stokesia laevis, commonly known as Stokes' Aster, is a clump-forming perennial native to the southeastern United States. It typically grows to a height of 1 to 2 feet and features lance-shaped, semi-evergreen leaves. The plant is prized for its showy, aster-like flowers that bloom from summer to fall in shades of blue, lavender, pink, or white. It's primarily an outdoor plant, valued for its long bloom period, attractiveness to pollinators, and ease of cultivation in gardens and borders. Indoor cultivation is challenging due to high light requirements.

❓ Frequently Asked Questions — Comparing These Plants
Kale (Ornamental)
What are the light requirements for Kale (Ornamental)?
Ornamental kale needs at least 6 hours of direct sunlight per day to develop its best color. In hotter climates, providing some afternoon shade can prevent the leaves from scorching. If growing indoors, place near a south-facing window or supplement with grow lights. Insufficient light can result in leggy growth and faded colors. Rotate the plant regularly to ensure even light exposure on all sides. If the plant is not getting enough light, the colors will be less intense and the leaves may turn more green than purple or pink.
How do I care for Kale (Ornamental)?
Ornamental kale thrives in cool weather and requires full sun to partial shade. Plant in well-draining soil with a slightly acidic to neutral pH. Water regularly, keeping the soil consistently moist but not waterlogged, especially during dry periods. Fertilize every 2-3 weeks with a balanced liquid fertilizer diluted to half strength, especially during the growing season to encourage vibrant colors. Deadhead any fading or damaged leaves to maintain a tidy appearance and promote new growth. Protect from extreme cold and frost, as this can damage the foliage. Mulch around the base of the plant to retain moisture and suppress weeds. Monitor for pests such as aphids and cabbage worms, and treat accordingly with insecticidal soap or neem oil.
How do I propagate Kale (Ornamental)?
Ornamental kale is typically grown from seed, but it can also be propagated by stem cuttings.
Stokesia
What are the light requirements for Stokesia?
Stokesia requires at least six hours of direct sunlight per day to thrive and produce abundant blooms. While it can tolerate partial shade, especially in hotter climates, insufficient sunlight can lead to leggy growth and reduced flowering. Choose a location in your garden or on your patio that receives full sun for the best results. If growing Stokesia indoors in containers, place it near a sunny window or supplement with grow lights to ensure adequate light exposure. Rotate the plant regularly to ensure even light distribution on all sides. Monitor the plant for signs of inadequate light, such as elongated stems or pale leaves, and adjust its location accordingly.
How do I care for Stokesia?
Stokesia thrives in well-draining soil and prefers full sun to partial shade. Water regularly, especially during dry periods, ensuring the soil remains consistently moist but not waterlogged. Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant blooms. Deadhead spent flowers regularly to encourage continuous blooming throughout the summer and fall. In colder climates, provide winter protection by mulching around the base of the plant. Prune back the foliage in late winter or early spring to encourage new growth. Stokesia is relatively pest and disease-resistant, but monitor for common garden pests like aphids and spider mites. Proper air circulation helps prevent fungal diseases. Regular maintenance ensures a healthy and vibrant plant.
How do I propagate Stokesia?
Stokesia can be propagated through division, stem cuttings, or seed. For division, carefully dig up the plant in early spring or fall and divide the root ball into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in well-draining soil. For stem cuttings, take 4-6 inch cuttings from new growth in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in moist potting mix and keep them humid until they root, which usually takes a few weeks. Seeds can be sown indoors or directly in the garden in spring.
