China rose (Rosa 'Mutabilis')
Rosa 'Mutabilis', a dynamic China rose, offers continuous color change from yellow to deep red, blooming from May to frost in zones 6-9.
Complete Plant Information
Overview
Rosa ‘Mutabilis’, commonly known as the China rose, stands out in the garden due to its mesmerizing, continuously changing flower hues. This old garden shrub rose opens a fresh display each day, transitioning from soft yellow to vibrant orange, pink, and finally a deep reddish tone on the same plant. This characteristic makes the shrub in full bloom a living spectrum of color, often earning it the common nickname ‘butterfly rose’.
As a repeat-blooming shrub, Rosa ‘Mutabilis’ provides color interest consistently from late spring through the first frosts. It forms a rounded, manageable shape, typically reaching 3 to 6 feet in height, making it versatile for various garden placements. Gardeners value this China rose not only for its continuous floral show but also for its relatively tough nature as a hybrid shrub rose.
Successful cultivation focuses on providing adequate sunshine for the best flowering and disease resistance; however, it remains an excellent specimen plant for mixed borders or even formal hedges. Ensure good air circulation around the plant to maintain the health of the medium green foliage throughout the growing season.

How to Grow
Plant Rosa ‘Mutabilis’ during the dormant season when conditions are cool, ensuring it settles well before summer heat. This China rose performs best in medium moisture, slightly acidic, well-drained garden loams. While it tolerates part shade, achieving the best flowering display and maximizing disease resistance requires a location receiving full sun.
Water deeply and consistently, preferably in the mornings, avoiding sprinkling overhead water which can encourage foliar diseases. Good horticultural practice is key; maintain vigorous health by ensuring plenty of air circulation around the shrub. Applying a summer mulch will help conserve soil moisture, keep the root zone cool, and suppress competitive weeds.
Deadhead spent flowers regularly to maximize the duration of the rebloom cycle, which leads into autumn color. In regions experiencing very cold winters, crown protection may be necessary. Prune this shrub only as needed in late winter or early spring to shape the plant or remove dead wood.
Landscape Uses
The versatility of Rosa ‘Mutabilis’ allows it to anchor several garden designs. It is highly recommended for use as an informal hedge due to its dense habit and nearly continuous color display throughout the season. Alternatively, use this colorful China rose as a striking specimen plant where its unique color changes can be fully appreciated up close.
Consider planting Rosa ‘Mutabilis’ within mixed perennial borders, positioning it where its height (3-6 ft) provides a mid-layer backdrop, ensuring it has companions that appreciate similar sun and soil needs. Its ability to blend cottage garden charm with defined structure means it works beautifully near foundations or within dedicated rose gardens.

Noteworthy Characteristics
Rosa is a genus of about 150 species of deciduous (occasionally evergreen) shrubs and climbers noted for their beautiful, often fragrant, single, semidouble or double flowers which are borne singly or in clusters on often prickly stems clad with 5-9 leaflets often having toothed margins. Shrub roses are usually large-growing bushes between 4-10 feet tall and as wide. They are a very diverse group of hybrids and usually produce clusters of flowers several times a year but some may bloom just once in spring. Genus name comes from the Latin name for rose. ‘Mutabilis’, a China rose, is a rounded, repeat-blooming, old garden shrub rose which grows 3-6’ tall (typically to 3’ in northern climates and taller in southern climates). Features clusters of slightly fragrant, single flowers (3” diameter) which bloom in May and repeat throughout the summer into fall. Flowers change color (mutate as the cultivar name suggests) as they mature, opening yellow and changing to orange, pink and finally deep pinkish-red. Thus, a shrub in full bloom will feature a wide spectrum of flower colors.

Potential Problems
Roses, in general, are susceptible to many diseases, including common issues like black spot, powdery mildew, and rust, and insect pests like aphids and spider mites. While Rosa ‘Mutabilis’ exhibits good disease resistance for a China rose, consistent vigilance is crucial, especially in humid climates. Implementing good cultural practices—such as pruning for air flow and destroying fallen leaves during dormancy—is the first defense. Applying regular preventative fungicide treatments throughout the growing season is often required to manage persistent fungal outbreaks.

Companion Planting
Companion plants for Rosa ‘Mutabilis’ should share similar requirements for full sun and medium moisture, while also benefiting from the rose’s open structure. Consider pairing this China rose with traditional companions like Lavender (Lavandula) or Catmint (Nepeta), whose silvery foliage contrasts beautifully with the rose’s deep green leaves, and whose presence can help deter some pests. Hardy perennials like Salvias or ornamental grasses whose moderate height won’t compete with the rose’s 3-6 foot stature work well in front, providing varied textures when the rose is not in bloom.
Seasonal Care Calendar
Late Winter/Early Spring is the critical time for structural revision; prune Rosa ‘Mutabilis’ lightly or as needed before new growth begins. As spring emerges, focus on preventative care—monitor foliage for signs of black spot or mildew and apply appropriate treatments if cultural controls are insufficient. Summer care centers on consistent, deep watering in the morning, avoiding the foliage. Throughout the flowering season, deadhead faded blooms to encourage continued flower production from this excellent repeat bloomer.
