The ‘Chicago Fire’ Burning Bush is a popular choice for home landscapes, valued for its striking autumnal display. This deciduous shrub transforms from lush green to an intense scarlet in the fall, creating a captivating focal point.
Distinctive Features of ‘Chicago Fire’ Burning Bush
The ‘Chicago Fire’ cultivar of Euonymus alatus typically grows to a mature height of 8 to 10 feet with a spread of 6 to 8 feet, forming a dense, rounded shape. It is known for its intense, fiery red fall foliage, complemented by small, yellow-green flowers in spring and red-orange berries that appear in fall and persist into winter. Beyond its seasonal color, ‘Chicago Fire’ also features interesting corky wings on its branches, which contribute to its visual appeal, particularly during the winter months when foliage has dropped.
Growing and Caring for ‘Chicago Fire’ Burning Bush
Site Selection and Soil
This shrub performs well in a range of light conditions, from full sun to partial shade, though full sun exposure encourages the most intense fall color. It adapts to various soil conditions, including normal, clay, or heavy soils, and is not particular about soil type or pH. However, well-draining soil is important, as consistently soggy or wet conditions can lead to root rot.
Planting Instructions
Dig a hole that is at least 6 inches wider and the same depth as the root mass or container. For container-grown plants, thoroughly saturate the root ball before planting. Ensure the top of the root ball is level with or slightly higher than the surrounding soil surface. Backfill the hole with soil, tamping gently to remove air pockets, and water thoroughly to settle the soil around the roots. Applying a 2 to 3-inch layer of mulch around the base, away from the stem, can help retain soil moisture.
Watering Needs
‘Chicago Fire’ Burning Bush requires consistent watering during its establishment period, which typically lasts about six weeks after planting. During this time, water the plant every 2 to 4 days initially, then at least once per week. Once established, the shrub becomes drought-tolerant and generally has low to moderate watering needs, requiring water primarily during extended dry periods. To check soil moisture, insert a finger about 3 inches into the soil; if it feels dry, a thorough soaking is beneficial. Direct water at the base of the plant to saturate the soil, avoiding wetting the foliage to prevent fungal issues.
Fertilization
‘Chicago Fire’ Burning Bush is not a heavy feeder and generally does not require extensive fertilization once established. Young shrubs can benefit from a balanced, all-purpose fertilizer applied in early spring before new growth begins. For mature plants, additional fertilizer is generally not necessary and can even promote excessive growth, which may increase its potential for spreading.
Pruning Techniques
Pruning ‘Chicago Fire’ Burning Bush helps maintain its shape and health. Routine pruning can be done at any time, but major or rejuvenation pruning is best performed in late winter or early spring before new growth emerges. To encourage a fuller plant and better air circulation, thin out dense interior branches, cutting them back to their point of origin. For neglected shrubs, rejuvenation pruning involves cutting the entire bush down to a few inches above ground level, promoting new, vigorous growth. When forming a hedge, keep the base wider than the top to allow light to reach all parts of the shrub, preventing lower branches from dying off.
Pest and Disease Watch
The ‘Chicago Fire’ Burning Bush is generally considered a low-maintenance plant with good resistance to common pests and diseases. It is not typically bothered by insects or diseases. Regular observation can help detect any unusual changes, allowing for timely intervention.
Best Uses for ‘Chicago Fire’ in Your Landscape
The ‘Chicago Fire’ Burning Bush offers versatile applications in landscape design due to its vibrant fall color and adaptable growth habit. It serves as an excellent specimen plant, creating a dramatic focal point with its intense scarlet foliage. Its dense form and substantial size make it suitable for use as a privacy screen or a formal or informal hedge. It can also be incorporated into foundation plantings or used to soften architectural angles around a home.
Important Considerations Before Planting
The common burning bush (Euonymus alatus), from which ‘Chicago Fire’ is a cultivar, is classified as an invasive species in many regions. Its aggressive growth and prolific seed dispersal allow it to escape cultivation and outcompete native plants, disrupting local biodiversity. It is advisable to check local regulations regarding its planting and sale, as some states have banned its use. Even where not prohibited, considering native alternatives is a responsible choice. If already planted, managing its spread by removing berries and controlling seedlings can help mitigate its environmental impact.
