Border forsythia (Forsythia × intermedia 'Variegata')
Forsythia × intermedia 'Variegata' offers brilliant yellow blooms and creamy variegated foliage. This low-maintenance Border forsythia is hardy in Zones 5-8, ideal for hedges.
Complete Plant Information
Overview
The Forsythia × intermedia ‘Variegata’, commonly known as Border forsythia, is celebrated as one of the earliest harbingers of spring, blanketing the landscape in brilliant golden flowers often before new leaves emerge. What sets this specific cultivar apart is its attractive foliage; the ovate leaves are bright green artfully marked with creamy variegation, offering interest even after the spectacular spring bloom fades. This deciduous shrub is valued for its vigorous growth, reaching heights of 8 to 10 feet, making Forsythia × intermedia ‘Variegata’ an excellent choice for creating bold structural interest or screening. Gardeners appreciate the low maintenance requirements of Border forsythia, provided it receives adequate sun for the best floral display.

How to Grow
Plant Border forsythia in loose, well-drained soils. While it tolerates relatively poor and clayey soils, ensure the site receives full sun for the most abundant flower production; partial shade is acceptable but will reduce blooming intensity. Established shrubs show moderate drought tolerance, but consistent medium watering is ideal during establishment.
Maintenance is low, but pruning is essential to prevent an unkempt appearance. Perform necessary shaping and rejuvenation pruning immediately after the spring flowering concludes. Pruning after mid-July removes flower buds set for the following year. For rejuvenation, a major cut back of stems close to the ground can be executed every 3 to 4 years.
Vegetatively hardy in Zones 5 through 8, gardeners in colder Zone 5 locations should be aware that harsh winter temperatures or late spring freezes can damage flower buds, especially if temperatures drop below -5 degrees F. This shrub handles urban conditions well, requiring minimal intervention once properly sited.
Landscape Uses
The robust structure and colorful seasonal show of Forsythia × intermedia ‘Variegata’ make it highly versatile in landscape design. It excels when massed on banks or slopes, providing excellent erosion control combined with a burst of early season color. Grouping these shrubs in borders effectively creates a vibrant spring screen or backdrop for later-blooming perennials. Consider planting Border forsythia in cottage gardens or sunny woodland garden settings where its upright-arching habit can be appreciated.
These early bloomers pair effectively with late-flowering spring bulbs like tulips and daffodils, which emerge as the forsythia begins to fade, ensuring continuous color interest. Their structure also works well against evergreen backgrounds, which provide contrast to both the bright yellow bloom and the creamy variegation of the foliage in summer.

Noteworthy Characteristics
The Forsythia × intermedia, commonly known as border forsythia, is a deciduous hybrid noted for its brilliant, 4-lobed golden flowers blooming profusely along the branches in late winter or early spring. The cultivar ‘Variegata’ is particularly prized for its foliage, featuring bright green ovate leaves with creamy variegation, though the plant is often considered a “one-season wonder” after the initial floral display. This intermediate hybrid grows upright and mounded, typically reaching 8 to 10 feet tall, but requires timely pruning to manage its sometimes rampant growth habit.

- Deer
- Clay Soil
- Black Walnut
Potential Problems
Border forsythia generally exhibits low maintenance, but it is susceptible to certain aesthetic issues. Watch for common pests such as spider mites and aphids, which can affect the quality of the summer foliage. Fungal issues like leaf spot, as well as crown gall and dieback, can occur, often exacerbated by poor air circulation or overly wet conditions.
Deer generally avoid chewing on this shrub, offering a benefit in areas where browsing is common. However, the primary cultural challenge is managing the flower buds in colder climates. Vegetative hardiness extends to Zone 5, but the flower buds are susceptible to damage if winter temperatures drop below -5°F or if late spring frosts occur after the buds begin to swell.
Frequently Asked Questions
What hardiness zones is Border forsythia suitable for?
Forsythia × intermedia ‘Variegata’ is reliably hardy in USDA Zones 5 through 8.

This deciduous shrub generally matures to a height between 8 and 10 feet tall with a spread spanning 10 to 12 feet wide.
What sun exposure does Forsythia × intermedia ‘Variegata’ need?
For the best and most abundant yellow blossoms, this plant requires full sun, though it can tolerate partial shade.
When does Border forsythia bloom?
This iconic shrub typically flowers in early spring, usually from March into April, before the foliage fully emerges.
Conclusion
The striking early spring bloom of the Border forsythia ensures its place in cool-season landscapes, while the attractive creamy variegation of Forsythia × intermedia ‘Variegata’ extends its visual appeal through summer. Its low maintenance and tolerance for less-than-ideal soils make it a practical choice for many settings. Ensure you check your local climate suitability within Zones 5-8 and plan your pruning schedule immediately after flowering concludes for the best seasonal performance.
Companion Planting
When planning garden layers beneath your Border forsythia, focus on plants that either thrive in bright, early spring light before the shrub leafs out or those that tolerate the filtered light once the canopy fills in. Excellent companions for early color are spring bulbs like crocus, snowdrops, and daffodils, which bloom concurrently with or slightly before the forsythia.
For summer interest beneath established shrubs, consider groundcovers or perennials that prefer medium moisture and can handle the dappled shade cast by the maturing foliage. Hostas and certain shade-tolerant ferns work well, as they will not compete severely with the shrub’s root system once the forsythia is mature, and their contrasting leaf textures enhance the garden design.
Seasonal Care Calendar
Early Spring (Pre-Bloom): Monitor weather forecasts for late frosts, especially in Zone 5. If severe cold is predicted, minor protection may be necessary, though pruning should be avoided until flowering is complete.
Post-Bloom (Late Spring/Early Summer): This is the critical pruning window for controlling size and shape. Immediately after the yellow flowers fade, shear lightly for shaping or hard-prune older wood for rejuvenation. Avoid fertilizing unless soil tests indicate a deficiency, as too much nitrogen encourages leafy growth over flowers.
Summer/Fall: Water consistently, ensuring the medium moisture level is maintained, especially during dry spells. Once established, Forsythia × intermedia ‘Variegata’ is quite drought tolerant. Halt any significant pruning by mid-July to ensure next year’s flower buds are not removed. Raking up fallen leaves helps reduce overwintering pests and diseases.
