Aubrieta vs Leyland Cypress Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Aubrieta
Aubrieta deltoidea
Aubrieta deltoidea, commonly known as Rock Cress, is a low-growing, spreading perennial plant prized for its vibrant spring blooms. It forms a dense mat of small, gray-green, slightly hairy, deltoid (triangular) leaves. In spring, it becomes covered in a profusion of small, four-petaled flowers, typically in shades of purple, lavender, pink, or blue. It's primarily grown outdoors in rock gardens, walls, or as ground cover. While technically possible to grow indoors, it's challenging to replicate the necessary conditions for optimal flowering and overall health.
Leyland Cypress
× Cuprocyparis leylandii
The Leyland Cypress is a fast-growing evergreen conifer, typically grown outdoors as a hedging or screening plant. It exhibits a dense, columnar to pyramidal growth habit. Its foliage is scale-like, soft to the touch, and typically a rich green color, though cultivars offer variations like gold or blue-green. It is not naturally an indoor plant and will struggle to thrive indoors due to its high light and space requirements. People grow it for its rapid growth, ability to create dense privacy screens, and adaptability to various soil conditions.

❓ Frequently Asked Questions — Comparing These Plants
Aubrieta
What are the light requirements for Aubrieta?
Aubrieta requires at least six hours of direct sunlight per day for optimal flowering. In hotter climates, providing some afternoon shade can prevent scorching of the foliage. A south-facing location is ideal, but east or west-facing sites can also work well if they receive sufficient sunlight. Insufficient light can lead to leggy growth, reduced flowering, and faded colors. If growing Aubrieta in containers, rotate them regularly to ensure even exposure to sunlight. Observe the plant’s growth and flowering patterns to determine if it is receiving adequate light. Adjust the location or provide supplemental lighting if necessary to promote healthy growth and abundant blooms.
How do I care for Aubrieta?
Aubrieta thrives in full sun to partial shade. It prefers well-drained, slightly alkaline soil. Water regularly, especially during dry periods, but avoid overwatering to prevent root rot. Fertilize in early spring with a balanced fertilizer to promote vigorous growth and abundant blooms. Prune after flowering to maintain shape and encourage reblooming. Deadhead spent flowers to prevent seed production and redirect energy into further flowering. Aubrieta is generally hardy and can tolerate frost, but mulching around the base of the plant can provide extra protection in colder climates. Monitor for pests and diseases, and treat promptly if necessary. Provide good air circulation to prevent fungal problems. Proper care will ensure a long-lasting and vibrant display of color.
How do I propagate Aubrieta?
Aubrieta can be propagated by division, stem cuttings, or seed. For division, carefully dig up the plant in spring or fall and divide the root ball into smaller sections. For stem cuttings, take 4-6 inch cuttings in late spring or early summer, remove the lower leaves, and root them in moist potting mix. Keep the cuttings in a humid environment until they develop roots. Seeds can be sown directly in the garden in spring or fall. Keep the soil moist and provide adequate sunlight. Division is the easiest and most reliable method.
Leyland Cypress
What are the light requirements for Leyland Cypress?
Leyland Cypress needs bright, indirect light to thrive indoors. Direct sunlight can scorch the foliage, so avoid placing it in a south-facing window without some form of light diffusion. An east- or west-facing window is ideal, providing ample light without the harshness of direct sun.
How do I care for Leyland Cypress?
Leyland Cypress thrives indoors with bright, indirect light. Ensure it receives at least 6 hours of sunlight daily, supplementing with grow lights if needed. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Maintain moderate humidity levels by misting regularly or using a humidifier.
How do I propagate Leyland Cypress?
Leyland Cypress can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from new growth in spring or early 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 and humid by covering it with a plastic bag or humidity dome. Place in bright, indirect light. Roots should develop in 6-8 weeks.
