Introduction & History

When the venerable Luxembourg nursery firm of Soupert & Notting introduced 'Clotilde Soupert' in 1890, they presented the gardening world with a Polyantha of unprecedented fullness and sophistication. Named for a member of the Soupert family, this rose combined the prolific clustering habit of the Polyantha class with the globular, fully packed bloom form previously seen only in the finest Tea and Bourbon roses. Each flower is a miniature peony, densely packed with 50 to 80 petals that open white with a variable pink center, shifting shade with temperature and age in a captivating display of chromatic instability. In cool weather the pink tones deepen to near-rose, while summer heat bleaches the blooms to purest white. The result is a bush that seems to wear a different dress each week, keeping the gardener perpetually intrigued. Clotilde Soupert became one of the most widely grown roses of the 1890s and remained a commercial bestseller for decades, helping to establish the Polyantha class as a serious force in ornamental horticulture.

Breeding History

Clotilde Soupert was bred by the firm of Soupert & Notting in Luxembourg and introduced in 1890. The recorded parentage is Mignonette (an early Polyantha) crossed with Madame Damaizin (a Tea rose), a combination that explains the unusually full bloom form and variable pink-and-white coloring. This cross united the clustering, remontant habit of the Polyantha parent with the petal count, form, and Tea fragrance of the seed parent. Soupert & Notting was one of the most respected rose nurseries of nineteenth-century Europe, and Clotilde Soupert became their signature cultivar, exported worldwide and sparking numerous sports and seedlings. It was among the most commercially successful roses of the 1890s and directly influenced the development of subsequent large-flowered Polyanthas.

Flower Form & Fragrance

Clotilde Soupert produces remarkably full, globular blooms packed with 50 to 80 petals, each flower 5 to 6 cm across. The form is cupped to rosette, reminiscent of a miniature peony or Bourbon rose, which was revolutionary for the Polyantha class at the time of introduction. Color is variable and temperature-dependent: in cool weather, blooms open with a pronounced pink to rose center fading to white at the edges, while in heat they open nearly pure white throughout. This chromatic shifting is one of the rose's most distinctive features. Blooms appear in clusters of 3 to 10 on short stems. Fragrance is moderate, sweet, and pleasant, with Tea rose undertones inherited from the Madame Damaizin parent.

Garden Design & Uses

Clotilde Soupert shines as a low bedding rose, border edging, or mass planting where its dense, globular blooms create a sumptuous carpet effect. Space plants 45 to 60 cm apart for continuous ground coverage. It excels in formal rose beds, Victorian-style plantings, and cottage garden borders. The white-and-pink color scheme pairs well with nearly any companion, but it is particularly effective with old-fashioned annuals like sweet alyssum, violas, and annual phlox. Use as a low hedge along pathways or as container specimens for terraces and balconies. Its compact size suits small urban gardens perfectly.

Growth Habit & Hardiness

Clotilde Soupert forms a compact, bushy, rounded plant typically reaching 45 to 75 cm tall and 45 to 60 cm wide. Growth is moderate, building a dense framework of short, sturdy canes well-clothed in foliage. Leaves are medium green, semi-glossy, with smallish leaflets. Thorn density is moderate with small, fine prickles. The overall habit is tidy and self-contained, rarely requiring structural pruning. Canes are strong enough to support the heavy, multi-petaled blooms without drooping. In warm climates the plant may grow slightly taller but maintains its compact character. It is one of the most neatly habited of all old garden roses.

Climate & Hardiness

Clotilde Soupert is hardy in USDA zones 6 through 9, tolerating winter temperatures to approximately -20°C (-5°F) with moderate dieback. In zone 6 it benefits from winter mulching and may die back to near ground level but regenerates well. It performs best in zones 7 to 9, where it maintains semi-evergreen foliage and blooms for an extended season. Heat tolerance is good, though blooms bleach to white more quickly in extreme heat. Humidity tolerance is adequate, though the densely packed petals can ball in prolonged rain.

Seasonal Care Calendar

Planting & Container Growing

Plant in full sun (minimum six hours) for best bloom production, though it tolerates light afternoon shade in hot climates. Preferred soil is well-drained, fertile, with pH 6.0 to 6.8. Space plants 45 to 60 cm apart for mass planting, 60 cm for individual specimens. Amend heavy clay with compost and coarse sand. Mulch with 5 to 7 cm of organic material. Water deeply at planting and establish consistent moisture during the first season.

Container Growing

Clotilde Soupert is superb for containers given its compact, rounded habit. Use a minimum 20-litre pot with good drainage. Fill with a rich, well-aerated potting mix blended with compost and perlite. Water when the top 3 cm of soil feels dry. Feed every two to three weeks during the growing season with a balanced rose fertilizer. The dense, globular blooms look magnificent at close range on a terrace or balcony. In zones 6 to 7, protect containerized plants over winter. Feasibility rating: 5/5.

Seasonal Care & Pruning

Spring: Clean out dead wood once buds begin to swell. Shape lightly to maintain the rounded form. Apply balanced granular fertilizer and fresh mulch. Summer: Water regularly, aiming for deep soaks rather than frequent light watering. Deadhead spent clusters promptly to prevent balling and botrytis. Feed again in early July. Autumn: Enjoy the enhanced pink tones that return in cool weather. Cease fertilizing by mid-August. Reduce watering gradually. Winter: Mulch the crown in zones 6 to 7. In zones 8 to 9, the plant may hold some foliage through mild winters.

Common Mistakes to Avoid

1. Overwatering or planting in poorly drained soil, which promotes root issues from its Tea rose heritage. 2. Not deadheading, which allows spent blooms to ball and develop botrytis in wet weather. 3. Expecting consistent color; the pink-white variation is a feature, not a flaw. 4. Heavy pruning that removes the compact twiggy structure that produces the best bloom display. 5. Planting in deep shade, where the already moderate vigor declines and disease pressure increases.

Propagation

Clotilde Soupert propagates well from softwood cuttings taken in late spring or early summer. Take 8 to 12 cm cuttings of semi-ripe wood, strip lower leaves, dip in rooting hormone, and root in a perlite and peat mix under a humidity cover. Rooting takes four to six weeks. Hardwood cuttings in autumn have fair success in mild climates. Own-root plants are preferred for their compact habit and longevity. Division of established clumps is possible. Budding onto rootstock is unnecessary. Difficulty rating: Easy to moderate.

Diseases & Pests

Clotilde Soupert has moderate disease resistance. The densely packed petals make blooms susceptible to botrytis (gray mold) and balling in wet weather, which is the primary management challenge. Black spot can occur in humid climates, particularly where air circulation is poor. Powdery mildew appears occasionally. Good garden hygiene, prompt deadheading of spent blooms, and adequate spacing are the best preventative measures. Aphids target new growth in spring. Spider mites may appear in hot, dry summers. Overall disease management is moderate, higher than many simpler-flowered Polyanthas.

Cut Flowers & Exhibition

The full, peony-like blooms of Clotilde Soupert make charming cut flowers for small arrangements and floating bowls. Cut when blooms are three-quarters open for maximum vase life. Stems are short at 10 to 20 cm, best suited to low bowls, teacups, and nosegays rather than tall vases. The white-and-pink blooms add a romantic, vintage quality to table settings. Vase life is four to five days.

Collector & Exhibition Notes

Clotilde Soupert is an important heritage cultivar representing the moment when Polyanthas gained the petal count and bloom sophistication previously reserved for Tea and Bourbon roses. It is exhibited in old garden rose and Polyantha classes, where the extraordinary petal count and variable coloring attract attention. For shows, select blooms showing both the pink center and white outer petals for maximum visual interest. The rose has produced several sports, including Striped Clotilde Soupert. It is commercially available from heritage nurseries and is maintained in major heritage rose collections worldwide.

Comparison with Similar Roses

Compared to Marie Pavie, Clotilde Soupert has far more petals per bloom (50 to 80 versus 30 to 40) and larger individual flowers, but Marie Pavie is thornless and slightly more disease-resistant. Against Perle d'Or, Clotilde Soupert is shorter, more compact, and white-pink versus apricot, with a fuller, more peony-like bloom form. Versus The Fairy, Clotilde Soupert blooms earlier and has larger individual flowers with more petals, but The Fairy is hardier and more disease-proof.

Heritage & Conservation

Clotilde Soupert is preserved in major heritage rose collections including the Europa-Rosarium Sangerhausen and various American heritage gardens. It represents a pivotal moment in Polyantha evolution when petal count and bloom refinement dramatically increased. The rose is commercially available from specialty nurseries. Its genetics contributed to subsequent developments in the Polyantha and early Floribunda lines. The Soupert & Notting nursery itself no longer exists, making this cultivar a living legacy of Luxembourg's contribution to world rose breeding.

Cultural Significance

Clotilde Soupert was one of the most commercially important roses of the 1890s, helping to popularize the Polyantha class among gardeners who had previously dismissed small-flowered roses. Its Luxembourg origins represent the important but often overlooked role of smaller European nations in rose breeding history. The rose was exhibited at world's fairs and international exhibitions of the era, winning numerous medals. It demonstrated that Polyanthas could achieve the bloom sophistication of the finest Tea and Bourbon roses while maintaining the ease and florferousness of the class.
