Dove Tree vs Sweet Alyssum Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Dove Tree
Davidia involucrata
Davidia involucrata, commonly known as the Dove Tree, is a deciduous tree prized for its distinctive, large, white bracts that resemble doves or handkerchiefs hanging from its branches in late spring to early summer. It typically grows to a height of 20-40 feet in cultivation, although it can reach greater heights in its native habitat. The tree has an upright, pyramidal growth habit when young, becoming more rounded with age. It is primarily grown as an ornamental tree for its unique floral display and attractive foliage. This tree is not suitable for indoor growing; it requires outdoor conditions to thrive.
Sweet Alyssum
Lobularia maritima
Sweet Alyssum is a low-growing, flowering annual (or short-lived perennial in warmer climates) known for its profuse clusters of tiny, fragrant flowers. It typically grows 4-12 inches tall and spreads 6-18 inches wide. The flowers are commonly white, but cultivars offer shades of pink, purple, and lavender. It's primarily an outdoor plant, valued for its ability to attract pollinators and its use in borders, rock gardens, and containers. While it can be brought indoors, it requires very bright light and cool temperatures to thrive.

❓ Frequently Asked Questions — Comparing These Plants
Dove Tree
What are the light requirements for Dove Tree?
Dove Trees thrive in bright, indirect light. Direct sunlight can scorch the leaves, especially during the hottest parts of the day. An east- or west-facing window is ideal, providing ample light without the harshness of direct sun. If you only have a south-facing window, position the tree a few feet away from the window or use a sheer curtain to filter the light.
How do I care for Dove Tree?
To successfully care for a Dove Tree indoors, provide bright, indirect light, ideally near an east- or west-facing window. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain moderate humidity levels, around 40-60%, using a humidifier or pebble tray if necessary.
How do I propagate Dove Tree?
Dove Trees can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem 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. Roots should develop in 6-8 weeks.
Sweet Alyssum
What are the light requirements for Sweet Alyssum?
Sweet Alyssum thrives in full sun, requiring at least six hours of direct sunlight daily. However, it can also tolerate partial shade, especially in hotter climates where intense afternoon sun can scorch the foliage. When planting Sweet Alyssum, choose a location that receives ample sunlight throughout the day. In indoor settings, place the plant near a sunny window or supplement with grow lights if natural light is insufficient. Insufficient light can lead to leggy growth and reduced blooming. Rotate the plant regularly to ensure even light exposure on all sides. Monitor the plant for signs of light stress, such as pale leaves or stretching stems, and adjust its position accordingly.
How do I care for Sweet Alyssum?
Sweet Alyssum thrives in full sun to partial shade, requiring at least six hours of sunlight daily for optimal blooming. It prefers well-drained soil with a slightly acidic to neutral pH. Water regularly, especially during dry periods, but avoid overwatering, which can lead to root rot. Fertilize every 2-3 weeks with a balanced fertilizer to promote continuous blooming. Deadhead spent flowers to encourage new growth and maintain a tidy appearance. Prune back leggy growth to maintain a compact shape. Sweet Alyssum is relatively low-maintenance, but regular care will ensure vibrant blooms and healthy growth. Protect from frost in colder climates, as it is an annual in most regions. Mulching helps retain moisture and suppress weeds.
How do I propagate Sweet Alyssum?
Sweet Alyssum can be propagated by seed, stem cuttings, or division. To propagate by seed, sow seeds indoors 6-8 weeks before the last frost or direct sow after the danger of frost has passed. For stem cuttings, take 4-6 inch cuttings from healthy stems and root them in water or moist potting mix. To propagate by division, carefully divide established plants in the spring or fall, ensuring each division has healthy roots and foliage. Plant the divisions in well-drained soil and water thoroughly. Keep the soil consistently moist until new growth appears. Provide adequate sunlight and fertilize regularly to promote healthy growth. These methods are relatively simple and can produce new plants quickly.
