Dove Tree vs Penstemon 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.
Penstemon
Penstemon spp.
Penstemon is a diverse genus of flowering plants, primarily herbaceous perennials, known for their vibrant, tubular flowers. They range in size from a few inches to several feet tall, with varying growth habits from upright to spreading. The flowers come in a wide array of colors, including shades of blue, purple, pink, red, and white, attracting pollinators like bees and hummingbirds. Penstemons are primarily grown outdoors in gardens and naturalized areas for their showy blooms, drought tolerance, and ability to attract wildlife. They are not typically grown indoors due to their high light requirements and need for specific environmental conditions.

❓ 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.
Penstemon
What are the light requirements for Penstemon?
Penstemon requires at least six hours of direct sunlight per day to thrive and produce abundant blooms. A location with full sun exposure is ideal. If growing Penstemon indoors, place it near a sunny window, preferably a south-facing one. Insufficient light can result in leggy growth, reduced flowering, and pale foliage. In hot climates, some afternoon shade may be beneficial to prevent scorching. Rotate the plant regularly to ensure even light exposure on all sides. Consider using grow lights to supplement natural light during the darker months of the year, especially for indoor plants.
How do I care for Penstemon?
Penstemon thrives in well-draining soil and prefers full sun, although some varieties can tolerate partial shade. Water regularly during the first growing season to establish a strong root system, then reduce watering frequency as the plant matures. Avoid overwatering, as this can lead to root rot. Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant blooms. Deadhead spent flowers to encourage continuous blooming. Prune back in late fall or early spring to maintain shape and remove any dead or damaged growth. Provide good air circulation to prevent fungal diseases. Mulch around the base of the plant to conserve moisture and suppress weeds. Penstemon is generally hardy but may benefit from winter protection in colder climates.
How do I propagate Penstemon?
Penstemon can be propagated by division, stem cuttings, and seeds.
