Leaf Description
|
- The foliage is bright yellow to golden, emerging in spring and remaining vibrant throughout the growing season.
- The leaves are oval-shaped with finely serrated edges, adding texture and brightness to garden beds.
- The yellow foliage maintains its color throughout summer, fading to shades of orange or copper in the fall.
|
Flower Description
|
- 'Candle Light' produces clusters of soft pink, delicate flowers in dense corymbs at the tips of its branches.
- The flowers bloom in profusion in mid to late summer, creating a lovely contrast against the golden-yellow foliage.
- The blooms are attractive to pollinators and last several weeks, adding color to the garden during the heat of summer.
|
Planting Instructions
|
- Plant in early spring or fall to allow the roots to establish before the growing season or winter dormancy.
- Choose well-drained soil and amend it with compost or organic matter if necessary. Spiraea is adaptable to a range of soil types, including sandy or clay soils, as long as the drainage is adequate.
- Space plants about 3 to 4 feet apart to allow for their mature spread.
|
Pruning & Maintenance
|
Prune in late winter or early spring to shape the shrub and encourage fresh growth. Deadhead spent flowers after blooming to encourage a second, lighter bloom in late summer. Regular pruning helps maintain a compact form and stimulates healthy growth. - Maintenance: Apply mulch around the base of the plant to retain moisture, suppress weeds, and protect the roots from temperature extremes. This also helps conserve water in dry conditions.
|
Water Needs
|
- Water regularly during the first growing season to help establish deep roots. Once established, 'Candle Light' is moderately drought-tolerant and only requires occasional watering during prolonged dry periods.
- Avoid overwatering, as Spiraea prefers slightly dry to moderately moist conditions.
|
Light Needs
|
- Full sun is ideal for the best foliage color and flower production. It requires at least 6 hours of direct sunlight per day.
- In hotter climates, it can tolerate some light afternoon shade, but too much shade may result in reduced flower production and less vibrant foliage.
|
Harvesting
|
Spiraea is not typically used for cut flowers but can be harvested for casual or cottage-style floral arrangements. – Best time to harvest: Mid-morning after dew has dried, when flower clusters are fully open
– Harvesting tips:
– Use clean pruners and cut just above a leaf node
– Strip lower foliage to avoid rot in water
– Combine with airy fillers or wildflowers for informal arrangements
– Vase life: Moderate—about 5 days depending on conditions
– Deadheading: Encouraged after blooming to promote a clean appearance and possible light reblooming |
Fertilizing
|
Fertilize in early spring with a balanced, slow-release fertilizer to encourage healthy growth and abundant blooms. If the soil is already fertile, additional fertilization may not be necessary. Organic compost can be added around the base in spring to improve soil health. |
Additional Care Tips
|
- Pests & Diseases: Spiraea 'Candle Light' is relatively pest-free but may occasionally suffer from aphids or powdery mildew in humid conditions. Ensure good air circulation and avoid overhead watering to reduce the risk of fungal issues.
- Cold & Heat Tolerance: Hardy in USDA zones 4-8, this shrub can tolerate both cold winters and hot summers. In colder climates, apply a layer of mulch to protect the roots during the winter months.
- Drought Tolerance: Once established, 'Candle Light' is moderately drought-tolerant but will benefit from supplemental watering during dry periods.
