Diplacus ‘Burst™ Orange’ – A Fiery Native Bloom for Modern Gardens
Diplacus ‘Burst™ Orange’, commonly known as Burst Orange Monkeyflower, is a dazzling, compact shrub that captures attention with its radiant reddish-orange blooms and resilient nature. Bred from the hardy Diplacus aurantiacus, this cultivar is part of the innovative Burst Series developed by Ball Horticultural Company. With brilliant color, an upright, mounding habit, and adaptability to dry gardens, ‘Burst Orange’ makes a memorable statement in both native and ornamental landscapes.
Botanical Background
Diplacus ‘Burst Orange’ belongs to the Phrymaceae family, which previously fell under Scrophulariaceae. This perennial hybrid draws its lineage largely from Diplacus aurantiacus, the Sticky Monkeyflower, native to California’s rocky slopes and chaparral. The name Diplacus comes from the Greek words “di” (two) and “plax” (broad surface), referencing the split seed capsule.
Although the classification has evolved, many nurseries still list it under Mimulus, its former genus. ‘Burst Orange’ was introduced in 2013 and holds U.S. Plant Patent #29,434. It was bred for greater flower size, compact form, and adaptability.
Description
This small shrub reaches 18 to 24 inches (45 to 60 cm) in height and width, forming a tidy, well-branched mound. Its deep green, glossy foliage provides a lush contrast to its flamboyant flowers. Each bloom is large for a monkeyflower, flaunting a rich, dark orange hue with a soft yellow-orange throat. The five frilly lobes form a two-lipped shape—a hallmark of the Diplacus genus.
Blooms appear nearly year-round in frost-free coastal gardens, with a peak in spring and early summer. In inland areas, flowering may decline during hot midsummer periods but can return with cooler fall weather.
Ideal Growing Conditions for Diplacus ‘Burst™ Orange’
Light
Diplacus ‘Burst Orange’ flourishes in full sun near the coast but benefits from light afternoon shade in hotter inland areas. Too much shade may reduce flower production.
Soil
Well-drained soil is essential. It adapts to sandy, rocky, or loamy soils and even thrives in serpentine soils. Avoid heavy clay unless it is amended for drainage.
Watering
Low water needs make this monkeyflower a great choice for drought-tolerant or xeric gardens. After establishment, it prefers to dry out between waterings. Overwatering may lead to root rot and reduce plant longevity. For potted plants, water more frequently but allow soil to drain thoroughly.
Temperature and Hardiness
Diplacus ‘Burst Orange’ is hardy down to 15-20°F (-9° to -6°C), making it suitable for USDA Zones 8-10. In areas with frost, some leaf drop may occur, but the plant typically rebounds in spring.
Fertilization
Minimal fertilization is best. A light application of balanced, slow-release fertilizer in early spring is sufficient. Avoid high-nitrogen products, which can produce excessive foliage at the expense of flowers.
Pruning and Maintenance
To maintain a compact, blooming plant:
- Pinch back new growth in early spring.
- Deadhead spent blooms regularly.
- Cut back lightly after major flowering flushes to encourage rebloom and rejuvenate the foliage.
Landscape Uses
- Coastal gardens
- Mediterranean-style plantings
- Native plant borders
- Butterfly and hummingbird gardens
- Slopes, rock gardens, or containers
It works beautifully with other dry-loving natives like Salvia spathacea, Artemisia californica, or Eriogonum fasciculatum.
Wildlife and Companion Benefits
Hummingbirds and native bees find the tubular flowers irresistible. The plant is also considered deer-resistant, adding to its appeal for low-maintenance gardens.
Propagation of Diplacus ‘Burst™ Orange’
You can propagate Diplacus ‘Burst Orange’ by softwood cuttings taken in spring or early summer. Seeds are also viable, though they may not come true to type. For best results, keep cuttings in a humid, well-lit environment until rooted.
Seasonal Notes
In summer, especially in hotter inland zones, the plant may enter a semi-dormant state. Let it rest by reducing irrigation and giving it partial shade. Fall rains and cooler temperatures usually trigger renewed growth and flowering.
Summary
Diplacus ‘Burst™ Orange’ is an outstanding hybrid monkeyflower that brings fiery color and resilient beauty to water-wise gardens. With minimal input, it offers months of showy bloom, supports pollinators, and integrates seamlessly into both native and ornamental settings. Whether planted en masse or in containers, this compact powerhouse continues to earn its place among California’s most captivating garden selections.
