Border forsythia (Forsythia × intermedia 'Courdijau' GOLDEN PEEP)
Discover Forsythia × intermedia 'Courdijau' GOLDEN PEEP, a dwarf Border forsythia perfect for low-maintenance spring color in Zones 5-8.
Complete Plant Information
Overview
The Forsythia × intermedia ‘Courdijau’ GOLDEN PEEP stands out as a wonderfully compact variation of the classic Border forsythia. Unlike its larger cousins, this cultivar offers brilliant yellow spring flowers on a dwarf frame, reaching only 20 to 30 inches tall and wide, making it ideal for smaller gardens or edging. This deciduous shrub is prized as a true harbinger of spring, brightening the landscape well before most other plants awaken.
A key appeal of Forsythia × intermedia ‘Courdijau’ GOLDEN PEEP is its low maintenance needs combined with reliable performance across USDA Zones 5 through 8. While it thrives in full sun for the best flower production, it tolerates partial shade, offering flexibility in landscape design. Its adaptability extends to soil types, succeeding even in clay-heavy conditions.
As a derivative of the hybrid Forsythia × intermedia, the ‘Courdijau’ selection provides that signature explosion of golden color signaling the end of winter. Gardeners appreciate the dwarf habit of Forsythia × intermedia ‘Courdijau’ GOLDEN PEEP, which minimizes the need for heavy structural pruning required by many 6-to-10-foot varieties, though timely trimming is essential for maintaining shape.

How to Grow
Planting this deciduous shrub should be done in spring or fall in well-drained, loose soil. While Border forsythia tolerates relatively poor and clayey soils, ensuring good drainage is crucial. For maximum flower impact, choose a site receiving full sun; partial shade is acceptable but may reduce blooming intensity.
Once established, watering needs are medium, though these shrubs possess moderate drought tolerance. Maintenance for Forsythia × intermedia ‘Courdijau’ GOLDEN PEEP is generally low due to its compact nature. However, pruning must be timed correctly: immediately after spring flowering concludes. Pruning after mid-July will inadvertently remove the flower buds set for the following spring.
For rejuvenation or shaping, gardeners can remove old wood annually after blooming. Since flower buds are sensitive to hard freezes—typically lost below -5°F—plants in Zone 5 may occasionally have diminished flowering due to harsh winter temperatures or late freezes. This shrub offers good tolerance for urban environments, making it a versatile choice.
Landscape Uses
The compact stature of Forsythia × intermedia ‘Courdijau’ GOLDEN PEEP makes it exceptionally useful where space is limited or where a low border is required. It excels when grouped in garden borders, providing a vibrant, solid band of early spring color. This cultivar is perfectly suited for massing on banks or slopes, offering quick stabilization with minimal upkeep.
Consider utilizing this dwarf Border forsythia in cottage gardens wanting a traditional early bloomer without overwhelming the space. It also performs admirably in sunny areas of open woodland gardens, particularly if allowed to cascade slightly due to its prostrate growth habit. Its early bloom works well contrasted against emerging evergreens.
Because it fades into the background after its spectacular spring show, plan companions carefully. Pair it with later-blooming shrubs or perennials whose foliage will emerge as the forsythia leaves fully expand, creating continuous interest throughout the season after the golden burst of commitment from Forsythia × intermedia ‘Courdijau’ GOLDEN PEEP.

Noteworthy Characteristics
Forsythia × intermedia, commonly known as border forsythia, is a deciduous hybrid shrub with upright-arching to spreading, often square-stemmed branches clad with ovate to lanceolate medium to dark green leaves (to 3-5” long and to 1” wide) which have toothed margins in the upper 1/2. Most cultivars mature to 6-10’ tall spreading to as much as 12’ wide, but some compact cultivars rise to only 30” tall. Shrubs are primarily noted for their brilliant, 4-lobed, often abundant golden flowers (each to 1 1/2” long) which typically bloom in clusters of 2-6 along the branches in late winter to early spring (February-March in Atlanta but March-early April in St. Louis). The cultivar ‘Courdijau’, commonly sold under the trade name of GOLDEN PEEP, is a small rounded compact form that grows to 20-30” tall and as wide, noted for its prostrate growth habit and bright yellow spring flowers, often blooming singly rather than in clusters, followed by ovate yellow-green leaves.
Tolerances
- Deer
- Clay Soil
- Black Walnut
Potential Problems
While generally robust, this shrub may show some susceptibility to cosmetic issues like leaf spot, crown gall, or stem dieback. Monitoring for common pests is advisable; watch actively for spider mites, aphids, the four-lined plant bug, Japanese weevil, and northern root-knot nematode, though deer typically avoid browsing the foliage.
Prevention centers on proper cultural care, especially good air circulation achieved through strategic pruning, which helps mitigate fungal issues like leaf spot. If pests are noted, targeted treatments for mites or aphids should be applied according to label directions, focusing treatments immediately after the flower petals drop.

Companion Planting
Selecting companions that appreciate similar sun and moisture levels ensures a cohesive planting scheme that looks great both during and after the brief Forsythia bloom. Pair this shrub with early-blooming bulbs like daffodils (Narcissus) or crocus, as they emerge concurrently or slightly earlier, sharing the stage briefly before disappearing.
For mid-to-late season interest when the yellow flowers of Forsythia × intermedia ‘Courdijau’ GOLDEN PEEP are gone, consider later-blooming perennials like Japanese painted ferns or variegated Solomon’s Seal. These choices provide textural contrast to the eventual green foliage and help mask any fade-out after spring flowering concludes.
Since this plant tolerates clay soil, group it with other tough, adaptable woody plants or perennials that thrive in medium moisture. Avoid plants demanding perfect, constantly enriched soil, favoring species that can handle the resilience needed by the Border forsythia in less-than-ideal garden spots.
Propagation Tips
Cultivars of Forsythia × intermedia are primarily propagated vegetatively to ensure genetic consistency, as growing from seed does not guarantee the desirable traits of the parent plant. The most successful method for gardeners propagating Forsythia × intermedia ‘Courdijau’ GOLDEN PEEP is through semi-hardwood stem cuttings taken immediately after the plant finishes flowering in spring.
When taking cuttings, select healthy, pencil-thick stems about 4 to 6 inches long, removing the lower leaves. Dipping the base of the cutting in rooting hormone powder significantly increases success rates before placing them into a moist, well-draining propagation medium, such as a peat and sand mix.
These cuttings root best when kept consistently moist and placed in a semi-shaded, protected environment, often utilizing bottom heat to speed up root development. Once roots have formed (usually within 6-8 weeks), the young Forsythia can be transplanted to a nursery bed for a year of establishment before moving to its final landscape location.
