Cole's Compact Burning Bush - 1 Gallon

Cole's Compact Burning Bush is a deciduous, multi-stemmed shrub in the Celastraceae family, bearing the botanical name Euonymus alatus 'Cole's Compact'. It is native to forests and scrublands of eastern Russia, Japan, China, and Korea, and was introduced to the United States as an ornamental. This cultivar is distinguished from the broader Euonymus alatus species by its notably finer-textured foliage, more refined branching structure, and slightly smaller overall stature. The leaves are elliptic to obovate, finely toothed along the margins, 1 to 3 inches long, and emerge a rich medium to dark green in spring, remaining clean and lush through summer before erupting into brilliant scarlet-red in autumn. The stems bear subtle corky ridges or "wings" - the origin of its common name - though these wings are typically less pronounced on 'Cole's Compact' than on the parent species. In late spring, small, four-petaled yellow-green flowers bloom in clusters but are mostly hidden by the foliage. These give way to reddish-purple fruit capsules approximately one-third inch in size that ripen in fall, split open to expose vivid orange-red coated seeds, and persist on the bare branches into winter. The overall habit is dense, rounded, and uniform, giving the shrub an almost architectural quality in the landscape year-round.

This cultivar is considered more compact than standard burning bush, which can reach 15 to 20 feet tall in time. Cole's Compact maintains a manageable, naturally tidy form and is suitable for planting beneath power lines. It grows slowly enough that it rarely demands aggressive pruning to keep it in bounds.

Cole's Compact Burning Bush is reliably hardy in USDA Hardiness Zones 4 through 8, tolerating winter temperatures as low as -30 degrees F. It is well-suited to the diverse climates of Southern Oregon and Northern California, thriving across a range of elevations up to approximately 6,500 feet. The shrub performs well in both mild coastal-influenced conditions and the more continental temperature swings common in inland valleys and foothills. Sunset Climate Zones 2 through 10 and 14 through 16 are considered appropriate for this plant. It is not suited to the warmest, most humid subtropical regions, and the most spectacular fall color develops where nights cool significantly in autumn.

Cole's Compact Burning Bush is highly adaptable with regard to light exposure and will grow in full sun, partial shade, and even close to full shade. However, light levels directly affect the intensity of the fall foliage display:

• Full Sun (6+ hours of direct sun daily): Produces the most spectacular, deeply saturated scarlet-red fall color. Best for maximum ornamental impact.
• Partial Shade (2-6 hours of direct sun daily): Still performs well with good fall color, though slightly less intense than in full sun.
• Full Shade: Tolerated, but fall color will be noticeably diminished and the overall display significantly reduced. Not recommended for ornamental plantings where fall color is the primary goal.

For the best results in Southern Oregon and Northern California, plant in a location that receives at least a half day of direct sun, particularly during the late summer and fall months.

One of Cole's Compact Burning Bush's greatest strengths is its remarkable soil adaptability. It is not demanding about soil composition or chemistry and will perform well across a very broad range of conditions:

• Soil Types: Clay, loam, silt, sand, or chalk-based soils are all acceptable. The shrub tolerates compacted soils and is known to be resilient in difficult urban planting sites.
• Soil pH: Highly adaptable - grows well in acidic, neutral, and alkaline soils. No special amendments to adjust pH are typically required.
• Drainage: Prefers moist, well-drained conditions but tolerates periodically dry soils once established. The one condition to avoid is wet, consistently waterlogged, or poorly drained soil, which can lead to root stress and twig blight.
• Black Walnut Tolerance: Noted to be tolerant of juglone, the chemical produced by black walnut trees that is toxic to many other plants.

During the first season after planting, consistent watering is important to help Cole's Compact Burning Bush establish a deep, extensive root system. Water deeply and thoroughly once or twice per week, allowing the soil to partially dry out between waterings. Avoid keeping the root zone constantly saturated. Once fully established - typically after the first full growing season - this shrub is notably drought tolerant and requires far less supplemental irrigation. In the hot, dry summers typical of Southern Oregon and Northern California, established plants benefit from deep watering every two to three weeks during prolonged dry spells. Mulching around the base of the plant helps retain soil moisture, moderate soil temperature, and reduce the frequency of irrigation needed.

Cole's Compact Burning Bush is a low-feeding shrub that typically thrives without heavy fertilization, especially when planted in average garden soil. An optional light annual feeding in early spring as new growth begins is sufficient to support healthy development:

• Apply a balanced, slow-release granular shrub fertilizer (such as a 10-10-10 formula) in early spring before bud break.
• Follow package instructions for application rates based on the size of the shrub.
• Avoid high-nitrogen fertilizers late in the growing season, as they can encourage soft new growth that may be damaged by early frosts.
• Fertilizing is not required every year for established, healthy shrubs growing in reasonably fertile garden soil - observe the plant's vigor and foliage color to determine need.
• A 2 to 3 inch layer of organic mulch replenished annually contributes slow-release nutrients as it breaks down and is generally all the feeding a mature plant requires.

Cole's Compact Burning Bush is a naturally well-shaped, low-maintenance shrub that requires minimal pruning under most circumstances. Its inherently dense, rounded habit means it rarely needs reshaping to look tidy. Here are key pruning guidelines:

• Best Time to Prune: Late winter to early spring, just before new growth emerges, is ideal for any structural shaping or size reduction. The plant can also be pruned at virtually any time of year without serious harm.
• Deadwood and Damaged Branches: Remove any dead, damaged, or crossing branches whenever they are noticed to maintain plant health and appearance.
• Formal Hedge: When used as a clipped formal hedge, shearing can be done in early summer after the initial flush of growth and again in mid to late summer if needed to maintain a crisp edge.
• Rejuvenation: If the shrub becomes overgrown over many years, it responds well to hard renovation pruning, tolerating significant cutbacks with strong recovery.
• Maintenance Level: Considered low maintenance overall. No deadheading, staking, or special seasonal care is required.

1. Timing: Plant in early spring or fall when temperatures are moderate and the risk of heat stress is lower. Fall planting is excellent for establishment in the mild climates of Southern Oregon and Northern California.
2. Site Selection: Choose a location in full sun to partial shade with well-drained soil. Allow adequate space for the mature spread of 6 to 8 feet in all directions from neighboring plants or structures.
3. Dig the Hole: Excavate a hole two to three times as wide as the root ball and approximately as deep. Wider is more important than deeper to encourage lateral root spread.
4. Planting Depth: Set the root ball so the top of the root mass sits level with or very slightly above the surrounding soil grade. Do not plant too deeply.
5. Backfill: Refill with the native soil removed, breaking up any large clods. Amendments are generally not necessary except in extremely poor soils.
6. Water In: Water thoroughly immediately after planting to settle the soil and eliminate air pockets around the roots.
7. Mulch: Apply a 2 to 3 inch layer of organic mulch (bark, wood chips, or compost) over the root zone, keeping it a few inches away from the main stem to prevent rot.
8. Spacing for Hedges: For a dense, continuous hedge or screen, space plants 4 to 6 feet apart on center, depending on how quickly you want the hedge to fill in.

Cole's Compact Burning Bush is one of the most versatile deciduous shrubs for the home landscape. Its adaptability, low maintenance needs, and outstanding fall color make it suitable for a wide variety of applications:

• Informal or Formal Hedge / Privacy Screen: Dense branching to ground level makes it excellent for blocking views and creating living boundaries. It can be left to grow naturally or clipped into a formal hedge.
• Foundation Planting: Its tidy, rounded habit and ground-level fullness make it ideal for anchoring corners and softening building foundations.
• Specimen or Accent Shrub: Planted alone as a focal point where its fall color display can be fully appreciated from a distance.
• Mass Planting: Grouped in three or more plants to create bold sweeps of fall color across large landscapes or slopes.
• Mixed Shrub Border: Blends well with conifers, ornamental grasses, and other deciduous shrubs, providing seasonal contrast and color punctuation in autumn.
• Erosion Control: Dense root system and adaptable nature make it useful on gentle slopes and embankments.
• Parking Lot and Urban Plantings: Its tolerance of compacted soils, pollution, and urban conditions makes it well-suited to commercial landscape applications.
• Near Evergreen Backdrops: Particularly striking when planted in front of or adjacent to evergreen trees or hedges, where the dark green background intensifies the brilliance of the scarlet fall foliage.

Cole's Compact Burning Bush pairs beautifully with plants that complement or contrast with its dramatic fall color. Consider the following companions for a well-rounded, multi-season planting:

• Ornamental Grasses (Blue Oat Grass, Blue Fescue, Purple Fountain Grass): The fine texture and cool blue or warm burgundy tones of ornamental grasses create a striking contrast against the rounded green form and fiery fall foliage.
• Japanese Maples: Their own brilliant fall palette of gold, orange, and deep red creates layered, harmonious autumn color alongside the burning bush's scarlet display.
• Evergreen Conifers (Arborvitae, Emerald Green, Spruce): Provide a rich dark green backdrop year-round that dramatically amplifies the impact of the red fall foliage.
• Fall-Blooming Asters and Chrysanthemums: Purple, lavender, pink, or white flowering asters and mums create a complementary cool-warm color contrast when the burning bush is at its peak.
• Ornamental Kale and Cabbage: Deep purple or cream seasonal color adds a layered textural contrast in the autumn garden bed.
• Gold-Leaved Plants (Golden Spirea, Gold Mop Cypress): Golden foliage creates a particularly vivid warm-toned contrast next to the intense scarlet red of Cole's Compact in fall.
• Black-Eyed Susans: Gold and brown late-season daisy flowers echo the warm autumn palette and extend seasonal interest in mixed borders.

Cole's Compact Burning Bush is considered generally pest and disease resistant, making it a very reliable and low-stress shrub to grow. However, there are a few conditions to be aware of:

• Spider Mites: The most common pest concern, particularly during hot, dry weather. Infestations appear as fine webbing on leaves and a stippled, dusty appearance to foliage. Treat with insecticidal soap, neem oil, or a strong jet of water to knock mites off leaves. Keeping plants adequately watered during dry spells helps prevent stress-related outbreaks.
• Scale Insects: Occasionally noted on euonymus species; small bumpy growths on stems are the sign. Treat with horticultural oil applied in late winter or early spring before new growth emerges.
• Twig Blight: A fungal problem that can occur when plants are growing in consistently wet soil or are subject to poor air circulation. Avoid overwatering and ensure good drainage. Prune and dispose of affected stems promptly.
• Powdery Mildew: Can occasionally appear on foliage, particularly in humid conditions with limited air circulation. Rarely serious; improve airflow by avoiding overcrowding and consider a fungicide if severe.
• Deer: Euonymus is attractive to deer and can be browsed, particularly when plants are young. In areas with high deer pressure, consider protective fencing for newly planted specimens or apply deer repellent sprays.

While Cole's Compact Burning Bush is not a native species, it does provide modest wildlife value in the garden:

• Birds: The reddish-purple fruit capsules that split open in fall to reveal bright orange-coated seeds are eaten by a variety of songbirds during the fall and winter months. This includes cedar waxwings, robins, and other berry-feeding species.
• Bees: The small late-spring flowers, though inconspicuous, attract bees and other small pollinating insects when in bloom.
• Deer: This shrub is frequently browsed by deer and is not considered a deer-resistant plant. In high deer pressure areas, protection may be needed for young plants.

Note: Because birds consume and distribute the seeds, planting near natural woodlands, riparian areas, or undisturbed native plant communities is discouraged to prevent spread beyond cultivated areas. It is well-behaved in typical urban and suburban garden settings.

All parts of Cole's Compact Burning Bush - including the leaves, stems, sap, and especially the fruit and seeds - contain compounds that are toxic if ingested in large quantities. This is important to be aware of for households with young children, dogs, cats, or horses.

• Toxic to: Humans (especially children attracted to the bright berries), dogs, cats, and horses.
• Symptoms of ingestion (large quantities): Abdominal pain, nausea, vomiting, diarrhea, weakness, chills, and in severe cases convulsions or coma.
• Severity: Generally considered low severity - toxic only if large quantities are consumed. The bright orange seeds inside the fruit capsules may attract curious children.
• Contact Dermatitis: Does not typically cause skin irritation from contact.
• Precaution: Educate children not to eat any part of the plant, and consult a poison control center immediately if ingestion is suspected.
