Complete Plant Information
Overview
Dipelta floribunda, commonly known as Rosy dipelta, offers year-round interest thanks to its exfoliating bark and abundant spring flowers. This vase-shaped shrub brings a touch of exotic structure to temperate gardens, maturing impressively in ideal settings. Gardeners appreciate its fragrant blooms and relatively straightforward cultural needs.
Native to the mixed forests of central China, Dipelta floribunda thrives in a variety of settings, provided the soil is fertile and well-drained. It is noted for maturing into a substantial specimen, reaching heights up to 15 feet, making it valuable for screening or as a bold border accent.
The visual appeal of Rosy dipelta continues beyond its flowering phase; the developing papery bracts surrounding the fruit provide interesting late-summer color before the mahogany bark takes center stage in winter. Planning for full sun placement ensures the best flowering display from this robust shrub.

How to Grow
The best time to establish Dipelta floribunda is during the dormant seasons, early spring or fall, allowing the roots time to settle before summer heat. Rosy dipelta prefers reasonably fertile, well-drained soils. Notably, it performs very well even if your soil has alkaline tendencies, unlike some acid-loving shrubs.
For consistent moisture, provide medium watering, especially for young plants establishment, though established shrubs are moderately adaptable. While fertilization is not strictly required, a balanced feed in early spring can support robust growth. Focus pruning efforts on removing dead or crossing wood as needed to maintain its natural vase shape.
The most spectacular flower display from Dipelta floribunda occurs when the plant receives full sun exposure. While it tolerates part shade, reduced flowering performance may result in shadier spots. Successful propagation is achievable either by seed or via cuttings taken at the appropriate time.
Landscape Uses
Rosy dipelta excels when utilized in structural roles within the landscape, fitting perfectly into informal hedges or screens where its height (up to 15 feet) provides substance. Its strong upright habit also lends itself well to defining the back lines of borders.
It is an excellent anchor plant for cottage gardens, providing fragrance and structure amidst softer perennial plantings. Consider placing it near patios or walkways where its fragrant flowers in late spring can be easily enjoyed. Its mature mahogany, exfoliating bark also offers significant winter interest.

Noteworthy Characteristics
Dipelta floribunda, commonly called rosy dipelta, is a vase-shaped deciduous shrub in the honeysuckle family that typically grows to 7-10’ tall, but matures in optimum growing conditions to 12-15’ tall with a spread to 9-12’ wide. It is native to mixed forest areas in central China. Notable features include: (a) fragrant, funnel-shaped, foxglove-like, pinkish-white flowers (1 1/4” long) with yellow throats which bloom singly or in clusters from late April to June, each flower having five rounded corolla lobes, (b) mahogany-colored bark which exfoliates with age in long strips providing winter interest after autumn leaf drop, (c) greenish papery bracts (peltate wings) at the corolla base which expand to surround the fruits (two-seeded achenes) as summer progresses, with the bracts turning tawny pink and finally bronze by late summer, (d) coarse, opposite, ovate to lanceolate, dull green leaves (2-4” long) which are tapered at the tip and base. Yellow and orange fall leaf color is usually not showy.Genus name comes from the Greek words di meaning two and pelte meaning shield in reference to the shield-like bracts covering the fruit.Specific epithet comes from the Latin word floribundus meaning abundant flowering in reference to bloom.

Propagation Tips
Given that propagation information is available, Dipelta floribunda can be increased from cuttings, which is often the preferred method for quickly obtaining genetically identical, mature plants. Timing the cuttings correctly—usually semi-hardwood cuttings taken in mid-summer—is crucial for success.
Alternatively, propagation from seed is also noted as a viable method, though seedlings may take longer to reach maturity and might exhibit slightly varied characteristics compared to cuttings. Stratification may be required for successful seed germination, depending on the sourcing of the seeds.
Companion Planting
When placing Dipelta floribunda in a mixed border, select companions that share similar cultural requirements for sun and water needs. Since Rosy dipelta thrives in full sun to part shade and tolerates alkalinity, consider pairing it with other robust, sun-loving shrubs that appreciate well-drained conditions.
Plants that peak slightly before or after the May to June bloom of Rosy dipelta can help extend the garden’s interest. For evergreen structure near the base, consider low-growing sedums or ornamental grasses that do not compete heavily for soil nutrients.
