Dove Tree vs Sea Holly 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.
Sea Holly
Eryngium spp.
Sea Holly (Eryngium spp.) is a genus of perennial flowering plants known for their thistle-like appearance and metallic blue or silver foliage. Typically found in coastal and grassland habitats, they feature spiky bracts surrounding a central cone-shaped flower head. These plants are grown for their unique architectural form, drought tolerance, and long-lasting cut flowers. They are primarily outdoor plants and can be challenging to grow indoors due to their high light requirements and need for well-draining soil. Their striking appearance makes them a popular choice for xeriscaping and adding textural interest to gardens.

❓ 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.
Sea Holly
What are the light requirements for Sea Holly?
Sea Holly demands abundant sunlight to flourish. Aim for a minimum of six to eight hours of direct sunlight each day. Insufficient light can result in leggy growth, reduced flowering, and duller foliage. When planting, choose a location that receives full sun exposure throughout the day. If growing in containers, position them in the sunniest spot possible, such as a south-facing patio or balcony. In regions with intense summer heat, provide some afternoon shade to prevent scorching of the foliage. Rotate potted plants regularly to ensure even light exposure on all sides, promoting balanced growth and abundant blooms.
How do I care for Sea Holly?
Sea Holly thrives in full sun and well-drained soil. Provide at least 6-8 hours of direct sunlight daily for optimal growth and flowering. Water deeply but infrequently, allowing the soil to dry out between waterings to prevent root rot. Fertilize sparingly with a low-nitrogen, high-phosphorus fertilizer in spring to encourage blooming. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers. Deadhead spent blooms to promote continued flowering. Sea Holly is relatively drought-tolerant once established, making it a low-maintenance plant. Ensure good air circulation around the plant to prevent fungal diseases. Protect from excessive winter moisture in colder climates. Amend heavy clay soils with sand or gravel to improve drainage.
How do I propagate Sea Holly?
Sea Holly can be propagated through division, root cuttings, or seed. For division, carefully dig up established clumps in spring or fall and separate the roots into individual plants, ensuring each has healthy roots and foliage. Replant immediately in well-draining soil. Root cuttings can be taken in late winter or early spring. Dig up the plant and take 2-3 inch root cuttings, planting them horizontally in a sandy soil mix. Keep moist until new growth appears. Seeds can be sown in spring or fall, but may require stratification (cold treatment) for optimal germination. Sow seeds in a well-draining seed-starting mix and keep moist until germination occurs.
