Diplacus ‘Burst™ Berry’ — The Brilliant Burst Berry Monkeyflower
Diplacus ‘Burst™ Berry’, sometimes known as Mimulus ‘Burst™ Berry’, and commonly known as Burst Berry Monkeyflower or Burst Berry Red Monkeyflower, is a dazzling addition to any garden that celebrates bold color, adaptable growth, and wildlife appeal. Belonging to the Phrymaceae family, this semi-evergreen perennial subshrub combines show-stopping blooms with easy-care qualities that make it a perfect choice for gardeners seeking vibrant, low-maintenance plants.
The genus Diplacus has undergone several taxonomic revisions in recent years, formerly classified under Mimulus. Thanks to DNA studies and botanical reevaluations, many species were reassigned, giving Diplacus its rightful place as a distinct genus. Diplacus Burst™ ‘Berry’ is one of the outstanding modern cultivars that continues to push this genus into the spotlight for contemporary gardens.
Striking Appearance of Diplacus ‘Burst™ Berry’
The standout feature of Diplacus ‘Burst™ Berry’ is its extraordinary bloom. The large, funnel-shaped flowers exhibit a deep, rich red hue, accented with a light orange-yellow throat. The two-lipped structure of the flower adds complexity and texture: the upper lip is split once, while the lower lip divides into three distinct, frilly lobes, creating a five-lobed, almost whimsical appearance. This unique floral form gives the plant its unmistakable monkey-faced resemblance, a trait common to many species within the Diplacus genus.
Beyond its blooms, the plant’s dark green foliage provides a perfect backdrop to highlight its vivid flowers. The glossy leaves are slightly sticky to the touch, contributing to the common name “Sticky Monkeyflower.” This semi-evergreen shrub maintains a tidy, upright form, typically reaching 45 to 60 cm (18 to 24 inches) in height and spread, though in ideal conditions it may grow slightly larger.
Blooming Season and Growth Habit
Diplacus ‘Burst™ Berry’ blooms profusely from spring through summer, often extending into autumn, especially in mild coastal climates where flowering can occur nearly year-round. Its peak display typically spans from April to July, delivering months of continuous color.
The plant grows in a compact, bushy habit, forming a pleasing mound that fits beautifully in borders, mixed beds, rock gardens, and xeriscape designs. Its fast growth rate allows it to establish quickly, rewarding gardeners with lush foliage and generous blooms in its first season.
How to Grow Diplacus ‘Burst™ Berry’
Light
Diplacus ‘Burst™ Berry’ thrives in full sun to light shade. In coastal regions where temperatures remain moderate, full sun exposure encourages maximum blooming. However, in hotter inland areas, providing some afternoon shade helps protect the plant from intense heat and prolongs its flowering season. Aim for at least 6 hours of direct sunlight daily for optimal performance.
Soil
Excellent drainage is crucial. Diplacus ‘Burst™ Berry’ prefers well-draining loamy soil but can adapt to various soil types, including sandy or rocky substrates, as long as drainage is sufficient. Heavy, poorly drained soils increase the risk of root rot, particularly during wet winter months.
Incorporating organic matter during planting improves both fertility and drainage but avoid overly rich soils that may encourage leggy growth at the expense of flowering.
Watering
Once established, Diplacus ‘Burst™ Berry’ displays impressive drought tolerance, making it ideal for water-wise and xeriscape gardens. During its establishment period, regular watering is essential to help the young plant develop a strong root system.
Mature plants benefit from infrequent deep watering, allowing the soil to dry almost completely between waterings. Overwatering can be detrimental, particularly in hot, humid conditions where root rot may develop.
In coastal areas, the plant may remain semi-evergreen and bloom sporadically through winter with minimal supplemental water. In hotter inland climates, allowing the plant to enter its natural summer dormancy helps preserve its vigor.
Fertilizing
Frequent fertilization is generally unnecessary for Diplacus ‘Burst™ Berry’. A light application of balanced fertilizer or compost in early spring can support healthy new growth, but excessive feeding may reduce flower production. In nutrient-poor soils, a second light feeding after the first bloom flush may promote reblooming.
Pruning
Pruning plays a key role in maintaining the health and appearance of Diplacus ‘Burst™ Berry’. After the main flowering period, lightly prune the plant to remove faded stems and encourage compact new growth. In early spring, additional light pruning helps shape the plant and stimulate further flowering.
Avoid heavy or severe pruning, as the semi-evergreen nature of the shrub means it may not regenerate well from hard cuts. Always leave some foliage below pruning cuts to support healthy regrowth.
Deadheading spent blooms throughout the season not only improves appearance but can also encourage prolonged flowering.
Propagation
Diplacus ‘Burst™ Berry’ may be propagated from softwood cuttings taken in late spring or early summer. Rooting hormone and a well-drained propagation mix improve success rates. While seed propagation is possible for many Diplacus species, named cultivars like ‘Berry’ are best propagated vegetatively to ensure genetic consistency.
Hardiness
Hardy to temperatures as low as -9°C to -12°C (15°F to 20°F), Diplacus ‘Burst™ Berry’ can survive light frost but may experience dieback during prolonged freezing periods. In colder zones, it benefits from mulching around the base for winter protection or may be grown as a container plant that can be sheltered during extreme cold.
Pests and Diseases
One of the many appeals of Diplacus ‘Burst™ Berry’ is its general resistance to most pests and diseases. Occasionally, aphids may appear, especially during periods of new growth, but these can typically be managed with insecticidal soap or a strong spray of water.
Root rot remains the most common problem when plants are grown in poorly drained soils or are overwatered. Ensuring proper soil drainage and cautious watering practices minimize this risk.
Deer generally avoid Diplacus ‘Burst™ Berry’, making it a valuable addition to gardens where browsing is a concern.
Wildlife Benefits
The vivid, tubular flowers of Diplacus ‘Burst™ Berry’ are highly attractive to pollinators, particularly hummingbirds, bees, and butterflies. Its nearly year-round blooming potential in mild climates offers consistent nectar sources that support local pollinator populations. This makes the plant not only a visual highlight but also an ecologically valuable choice for habitat gardens.
Garden Uses
Thanks to its versatility and vibrant display, Diplacus ‘Burst™ Berry’ fits effortlessly into a variety of landscape designs:
- Coastal gardens
- Rock gardens
- Xeriscapes and drought-tolerant landscapes
- Mixed perennial borders
- Containers and raised beds
- Pollinator and wildlife gardens
- Slopes or erosion-prone areas
Its compact size and upright habit make it an excellent filler between larger shrubs or as a colorful accent along pathways and garden edges.
Summary: The Vibrant Charm of Diplacus ‘Burst™ Berry’
With its glowing red blooms, low water needs, and strong performance in diverse conditions, Diplacus ‘Burst™ Berry’ exemplifies the modern monkeyflower’s horticultural potential. As adaptable as it is striking, it offers gardeners a vibrant, easy-care option that thrives with minimal intervention. Whether gracing a sun-drenched coastal border or brightening a dry inland garden, ‘Burst™ Berry’ delivers reliable color and enduring beauty throughout much of the year.
