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.

Mexican Bush Sage

Mexican Bush Sage

Salvia leucantha

Mexican Bush Sage is a perennial shrub prized for its velvety, often purple, flower spikes and aromatic foliage. It typically grows to a height of 3-4 feet and a similar spread. While primarily an outdoor plant, it's grown for its late-season blooms that attract pollinators like bees and hummingbirds. The plant's soft texture and vibrant colors make it a popular choice for gardens, borders, and containers. It is not naturally an indoor plant and requires very specific conditions to thrive indoors.

💡 Pro Tips For Comparing These Plants

Kale (Ornamental) Care Tips

Ornamental kale is primarily an outdoor plant and requires specific conditions to thrive indoors. Providing sufficient light and cool temperatures is crucial. Indoor growth is often less vibrant and shorter-lived than outdoor growth. Requires vigilant monitoring for pests and diseases.

  • Provide at least 6 hours of direct sunlight daily for best color development.
  • Water thoroughly when the top inch of soil feels dry.
  • Fertilize every 2-4 weeks during the growing season with a balanced liquid fertilizer.
  • Protect from extreme cold in winter.
  • Remove yellowing or damaged leaves to prevent disease.
❄️ Winter: Protect from extreme cold by covering with a frost blanket or moving to a sheltered location. Reduce watering frequency during periods of dormancy.
☀️ Summer: Provide shade during the hottest part of the day to prevent scorching. Ensure adequate watering to prevent wilting. Monitor for pests and diseases, which can be more prevalent in warmer weather.

Mexican Bush Sage Care Tips

Mexican Bush Sage is primarily an outdoor plant that thrives in full sun and well-drained soil. Indoor cultivation is challenging due to its high light requirements. It needs consistent watering and fertilization during the growing season. Pruning is essential to maintain its shape and encourage blooming. It is toxic to pets.

  • Provide full sun for optimal blooming.
  • Water deeply but infrequently, allowing the soil to dry out between waterings.
  • Prune after flowering to encourage bushier growth and more blooms.
  • Fertilize sparingly during the growing season.
  • Protect from frost in colder climates.
❄️ Winter: In colder climates, protect from frost by mulching around the base of the plant. Reduce watering during the dormant season. In very cold regions, consider growing it in a container that can be brought indoors.
☀️ Summer: Provide adequate water during hot, dry periods. Monitor for pests and diseases. Deadhead spent flowers to encourage continued blooming.

❓ 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.

Mexican Bush Sage

What are the light requirements for Mexican Bush Sage?

Mexican Bush Sage requires at least 6-8 hours of direct sunlight each day to thrive and produce abundant blooms. Insufficient light can result in leggy growth, reduced flowering, and pale foliage. When grown indoors, place the plant near a south-facing window where it can receive maximum sunlight. If natural light is limited, supplement with grow lights. Rotate the plant regularly to ensure even light exposure on all sides. A lack of sunlight can also make the plant more susceptible to pests and diseases. During the winter months, when sunlight is less intense, consider moving the plant to a brighter location or increasing the duration of grow light exposure.

How do I care for Mexican Bush Sage?

Mexican Bush Sage thrives in full sun and well-draining soil. Water thoroughly when the top inch of soil is dry, but avoid overwatering, which can lead to root rot. Fertilize every 2-3 weeks during the growing season (spring and summer) with a balanced fertilizer, switching to a bloom-boosting formula as flowering approaches. Prune lightly in late winter or early spring to remove dead or damaged growth and encourage bushier growth. Provide support if the plant becomes leggy. Ensure good air circulation to prevent fungal diseases. Repot every 1-2 years as needed. Protect from frost in colder climates. Mulch around the base of the plant to retain moisture and suppress weeds. Monitor for pests like aphids and spider mites, and treat promptly if detected.

How do I propagate Mexican Bush Sage?

Mexican Bush Sage can be propagated through stem cuttings, division, or seeds. 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 cutting in a well-draining potting mix and keep it moist. Roots should develop within a few weeks. For division, carefully dig up the plant in early spring and divide the root ball into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in separate pots or in the garden. Seeds can be sown indoors in early spring. Keep the soil moist and warm until germination occurs. Transplant seedlings outdoors after the last frost.
