Aubrieta vs Nicotiana 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.
Nicotiana
Nicotiana tabacum
Nicotiana tabacum is an annual herbaceous plant typically grown outdoors for its large leaves, which are commercially processed for tobacco products. It can reach heights of 1-3 meters. The plant features a sturdy stalk and broad, ovate leaves that are sticky to the touch. While it can be grown indoors, it requires very specific conditions and is primarily an agricultural crop. People cultivate it for its leaves, which contain nicotine.

❓ 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.
Nicotiana
What are the light requirements for Nicotiana?
Nicotiana flourishes in full sun, requiring at least 6 hours of direct sunlight per day for optimal blooming. However, in hotter climates, it can benefit from partial shade during the hottest part of the afternoon. Insufficient light can result in leggy growth and reduced flowering. When growing Nicotiana indoors, place it near a sunny window that receives ample sunlight. Rotate the plant regularly to ensure even light exposure on all sides. If natural light is limited, supplement with grow lights to provide the necessary illumination. The right amount of light is crucial for vibrant blooms and healthy growth.
How do I care for Nicotiana?
Nicotiana thrives in well-draining soil and prefers a location with full sun to partial shade. Water regularly, especially during hot, dry periods, allowing the top inch of soil to dry out between waterings. Fertilize every 2-3 weeks during the growing season with a balanced fertilizer or one formulated for flowering plants. Deadhead spent flowers to encourage continuous blooming. Provide support for taller varieties to prevent them from flopping over. Monitor for pests such as aphids and whiteflies, and treat as needed. In colder climates, Nicotiana is often grown as an annual, but it can be overwintered indoors or allowed to self-seed for the following year. Provide adequate air circulation to prevent fungal diseases. Prune as needed to maintain shape and remove any dead or damaged foliage.
How do I propagate Nicotiana?
Nicotiana is primarily propagated by seed. Collect seeds from dried flower heads or purchase seeds from a reputable source. Sow seeds indoors 6-8 weeks before the last frost. Sprinkle seeds on the surface of well-draining soil and lightly cover with vermiculite. Keep the soil consistently moist and provide bright, indirect light. Once seedlings have developed several sets of true leaves, transplant them into individual pots. Gradually acclimate seedlings to outdoor conditions before transplanting them into the garden. Nicotiana can also self-seed readily if allowed to drop seeds naturally. Division and stem cuttings are not typical methods for Nicotiana.
