Turn up the drama with Nightglow™ Diervilla. Also known as Diervilla splendens Nightglow™ ('El Madrigal'), this bush honeysuckle has dark, moody burgundy foliage that becomes more vivid in the fall. The high-contrast flowers in yellow are trumpet shaped and frequented by both butterflies and bees. This tough little shrub flowers from spring to summer and looks amazing next to plants with chartreuse or golden foliage.
This is an upright multi stemmed shrub with a mounding form. It is small and compact, maxing out at 2 - 3 feet high and as wide. It is deciduous and hardy to zone 4. It is usually ignored by deer and tolerant of dry and clay sites. Because of their short stature, Nightglow works well in foundation planting for a pop of color, as a low hedge, as an accent focal point, and in containers.
Nightglow™ Diervilla Care
Bush Honeysuckle grows well in full to partial sun and will exhibit more intense foliage color with at least 6 hours of direct sun. It is very adaptable to a variety of soil types as long as the soil drains well. It also adapts well to dry conditions and exhibits drought tolerance once established. Water regularly during the first growing season to establish a strong root system. Apply a well-balanced organic fertilizer in the spring.
Nightglow maintains a naturally compact, mounded shape that doesn’t require much pruning. To clean up any damaged or irregular branches, prune in early spring. Bush honeysuckle blooms on new wood, so you can prune away without worrying about removing next year’s buds.
Nightglow™ Diervilla Spacing
Space Nightglow™ Diervilla plants approximately 2 feet apart to form a low hedge or dense groundcover. Increase the spacing to at least 3 feet for accent planting. Nightglow is a good candidate for container gardens, provided the pot is at least 18 inches in diameter.

New Wood
?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
- When to Prune
- Late winter to early spring, before new growth starts
