Cedar vs Wallflower Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Cedar
Cedrus spp.
Cedrus species, commonly known as true cedars, are coniferous evergreen trees characterized by their aromatic wood, needle-like leaves arranged in spirals on long shoots and in dense clusters on short shoots, and barrel-shaped cones. They are large trees, typically reaching heights of 30-40 meters (100-130 feet) or more in their native habitats. Cedars are primarily outdoor trees, valued for their majestic appearance and use in landscaping. They are not naturally indoor plants and struggle to thrive in the confined conditions of indoor environments. People grow them for ornamental purposes, timber production, and their cultural significance.
Wallflower
Erysimum cheiri
Wallflower (Erysimum cheiri) is a short-lived perennial or biennial often grown as an annual. It's known for its vibrant, fragrant flowers that bloom in spring and early summer. The plant typically reaches a height of 12-30 inches. The flowers come in a range of colors, including yellow, orange, red, purple, and brown. Wallflowers are primarily outdoor plants, valued for adding color and fragrance to gardens, borders, and rockeries. While some attempt to grow them indoors, they often struggle due to insufficient light and humidity.

❓ Frequently Asked Questions — Comparing These Plants
Cedar
What are the light requirements for Cedar?
Indoor cedars thrive in bright, indirect light. Placing them near an east- or west-facing window is usually ideal. Avoid direct sunlight, especially during the hottest part of the day, as it can burn the delicate needles. Insufficient light can lead to leggy growth and yellowing foliage. If you don’t have access to sufficient natural light, consider supplementing with a grow light. Rotate your cedar regularly to ensure all sides receive adequate light. During the winter months, when sunlight is less intense, you may need to move your cedar closer to a window or increase the amount of supplemental light. Pay close attention to the plant’s growth and adjust its position accordingly.
How do I care for Cedar?
Indoor cedar trees require bright, indirect light; avoid direct sunlight, which can scorch the foliage. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Use a well-draining potting mix formulated for conifers or evergreens. Maintain moderate humidity, especially during dry winter months. Fertilize sparingly, only during the growing season (spring and summer), with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain the desired shape and remove any dead or yellowing foliage. Repot every 2-3 years, or when the plant becomes root-bound, into a slightly larger pot. Ensure adequate air circulation to prevent fungal diseases. Monitor for pests such as spider mites or scale and treat promptly. Provide stable temperatures, avoiding drastic fluctuations. Rotate the plant regularly to ensure even growth on all sides.
How do I propagate Cedar?
Cedar can be propagated through stem cuttings or air layering. For stem cuttings, take 4-6 inch cuttings from new growth in spring or early summer. Remove the lower needles and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist and humid. Rooting can take several weeks to months. For air layering, make a small incision in a branch, apply rooting hormone, and wrap the incision with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Once roots have formed, cut the branch below the roots and pot it up. Both methods require patience and careful monitoring. Maintain consistent moisture and humidity for successful propagation. Choose healthy, vigorous branches for the best results.
Wallflower
What are the light requirements for Wallflower?
Wallflowers require at least 6 hours of direct sunlight per day to thrive and produce abundant blooms. A south-facing window or sunny patio is ideal. Insufficient light can result in leggy growth and reduced flowering. If growing indoors, consider using a grow light to supplement natural light, especially during the winter months. Rotate the plant regularly to ensure even light exposure on all sides. Monitor the plant for signs of insufficient light, such as pale leaves or elongated stems. Adjust the placement accordingly to provide optimal light conditions.
How do I care for Wallflower?
Wallflowers thrive in full sun and well-drained soil. Water regularly, allowing the soil to dry slightly between waterings. Avoid overwatering, which can lead to root rot. Fertilize every 2-3 weeks during the growing season with a balanced liquid fertilizer to promote abundant blooms. Deadhead spent flowers to encourage continued flowering. Prune lightly after blooming to maintain shape. Protect from frost in colder climates by moving potted plants indoors or providing adequate cover. Wallflowers prefer cooler temperatures and can tolerate light frost. Ensure good air circulation to prevent fungal diseases. Regularly check for pests and address infestations promptly.
How do I propagate Wallflower?
Wallflowers are typically propagated by seed, but stem cuttings can also be used. For stem cuttings, take 4-6 inch cuttings from non-flowering stems in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix and keep them moist. Rooting should occur in 4-6 weeks. Alternatively, collect seeds from dried flower pods in late summer or fall. Sow the seeds indoors in early spring or directly into the garden after the last frost. Division is less common but possible with established clumps, carefully separating the roots and replanting.
