ROSA VIRIDIFLORA – green historic China rose - Smith
This extraordinary historic China rose brings a quietly theatrical presence to a family garden, its curious green pompon blooms suiting romantic, storybook borders and sheltered seating areas. As an own-root shrub, it develops with reassuring stability, building a discreet yet durable framework that fits comfortably into cottage-style planting and informal hedges. Over time, its well-anchored root system copes reliably even in exposed gardens where coastal wind and rain test less robust plants, while moderate size and bushy habit keep it visually balanced and easy to place. Cluster-flowered, strongly remontant blooms deliver a long season of interest with an unusual colour effect, especially attractive to collectors and those who favour a slightly eccentric, vintage look. Glossy mid-green foliage adds a healthy backdrop to summer perennials, and partial-shade tolerance lets you tuck it beside a path, arbour or kitchen-garden fence for a softer, more intimate mood. Own-root growth supports a long garden life with reliable regrowth after harder pruning or weather damage, settling in as a quietly distinctive highlight of your cottage-style border.
Usage options
| Target area | Reasoning |
|---|
| Romantic cottage border near a seating area |
The medium-sized, bushy, upright habit makes it easy to place in a mixed border without overwhelming nearby perennials or low hedging, while its rare green pompon blooms provide a conversation piece close to where you sit and entertain, especially for collectors. |
| Feature shrub by an arbour or arch |
Used as a specimen near an arbour, its gently upright framework and glossy foliage frame structures without demanding constant shaping; own-root growth gives long-term resilience and the plant can be refreshed by harder pruning once mature, suiting relaxed homeowners. |
| Small family garden bed or front garden strip |
Its 80–130 cm height and 60–100 cm spread fit well into modest front gardens and side beds, delivering historic character and repeat flowers on a scale that complements paths, driveways and low fencing, ideal for busy families. |
| Container on terrace, patio or balcony |
In a 40–50 litre or larger container it forms a compact, upright shrub with an extended flowering season, giving those with paved spaces or rented homes access to a distinctive historic rose without complex maintenance, appealing to space-conscious urbanites. |
| Naturalistic historic-rose collection or themed bed |
As a sport of ‘Slater’s Crimson China’ from the early 19th century, it brings genuine heritage value and botanical curiosity to collections of historical roses, offering a subtly theatrical green display prized by enthusiastic historians. |
| Mixed planting in partially shaded spots |
Its suitability for partial shade allows planting where sun is limited by buildings or taller shrubs; the foliage remains presentable and flowering continues reliably, making awkward side-return or corner beds more rewarding for casual gardeners. |
| Wind- and rain-exposed family plots |
Once established, the own-root system and moderately dense framework provide a steady, rooted presence that carries flowers without collapsing, even where frequent wind and rain would spoil more delicate blooms, reassuring practical owners. |
| Low informal hedge or repeated rhythm in a border |
Recommended planting distances allow informal rows or grouped plantings that read as a soft hedge; identical green blooms and mid-green foliage repeat rhythmically, giving structure with a gentle twist of character sought by design-aware beginners. |
Styling ideas
- COTTAGE-RIMMED PATH – Line a narrow garden path with spaced plants of this rose, underplanting with trailing bellflower for a soft, tumbling edge – ideal for romantic-pathway lovers.
- ARBOROUS TEA NOOK – Place a specimen near an arbour, pairing with Japanese honeysuckle to weave scent and texture around the seating area – perfect for afternoon-tea traditionalists.
- HISTORIC ACCENT BED – Combine it with other old roses and vintage perennials in soft whites and pinks so the green flowers stand out as a subtle curiosity – suited to heritage-rose enthusiasts.
- STRUCTURED POT GARDEN – Use a large container as a vertical anchor on a patio, surrounding it with terracotta pots of herbs for a relaxed kitchen-garden feel – appealing to small-space cooks.
- WINTER-FRAME BORDER – Plant against Midwinter Fire dogwood so the summer green blooms give way to glowing winter stems, keeping interest all year – attractive to four-season planners.

| Name and registration |
Rosa viridiflora, also known as Green Rose; a historic China shrub rose in the Heritage rose collection, marketed as a speciality old garden rose for beds, specimens and containers. |
| Origin and breeding |
Originated as a spontaneous sport of ‘Slater’s Crimson China’; bred by John Smith in the United States around 1827, later introduced into Europe in 1855 as a botanical curiosity. |
| Growth and structural characteristics |
Bushy, upright shrub reaching roughly 80–130 cm tall and 60–100 cm wide, with moderately dense, glossy mid-green foliage and only slight prickliness, suited to informal shaping or light hedging. |
| Flower morphology |
Small, double, ball-shaped to pompon flowers in clusters, with 26–39 petals; strongly remontant, providing abundant repeat flowering across the season when deadheaded to remove spent blooms. |
| Colour data and phenology |
Unique green flowers shifting from deep oil-green buds to vivid mid-green blooms, bronzing slightly in sun; colour retention is moderate, with a largely uniform mid-green surface in full flower. |
| Fragrance and aroma |
Fragrance is very weak and only barely perceptible, with a faint spicy character; the cultivar is grown primarily for its unusual visual effect rather than for scent or pollinator attraction. |

Double blooms usually set few hips; any produced are small, spherical, around 6–10 mm, in green to brownish tones, contributing minor late-season interest without heavy self-seeding. |
| Resistance and winter hardiness |
Hardy to about −21 to −18 °C (RHS H7, roughly USDA 6b); shows good resistance to powdery mildew and black spot, with moderate rust sensitivity, tolerating heat if watered during drought. |
| Horticultural recommendations |
Best at 55–60 cm spacing in beds or informal hedges; maintenance is medium, needing occasional plant protection and deadheading; suitable for partial shade and larger containers from 40–50 litres. |
