ISIDORA™ – golden-yellow flowerbed shrub rose
Bring a touch of soft cottage-garden sunlight to your front path with ISIDORA™, a compact, golden-yellow shrub rose that feels perfectly at home in Irish borders and small Dublin terraces, even where rainfall and mild summers are the norm. Its bushy, naturally rounded habit makes it easy to place in mixed planting, while the 40+ petalled, cup-shaped blooms open from deep golden buds into buttery-yellow cushions that look lovely under green, soft light. The mild, spicy fragrance lends a gentle, comforting note to everyday garden strolls, and the remontant flowering pattern delivers a reliable second flush when many other plants are fading. Grown on its own roots, ISIDORA™ is designed for long-term lifespan and steady recovery after pruning or weather damage, building strong roots in the first year, fuller shoots in the second, and a settled, consistently showy display by the third season – an easy-going, “girly” cottage accent for busy home gardeners.
Usage options
| Target area |
Reasoning |
| Front-of-house bed in a Dublin terrace street |
The compact shrub habit and moderate 55–85 cm height sit neatly beneath windows without blocking light, while golden-yellow clusters read clearly from the pavement and pair well with traditional brick or painted facades; ideal for style-conscious homeowners. |
| Cottage-style mixed border in a family garden |
ISIDORA™’s very double, cup-shaped flowers and warm golden tones echo classic cottage borders, threading easily between perennials and giving structure without dominating, suiting relaxed, romantic planting for nature-minded beginners. |
| Feature group in a small lawn or front garden |
Planted in threes or fives at the recommended spacing, its compact but spreading habit quickly forms a rounded golden mound, creating a cheerful focal point that remains proportionate to modest urban plots, appealing to busy gardeners. |
| Own-root rose bed for long-term planting |
As an own-root shrub, ISIDORA™ matures steadily into a stable, uniform clump that regenerates well from the base after hard pruning, offering dependable ornamental value over many years with fewer replacement worries for long-range planning buyers. |
| Lightly used family seating area or patio edge |
The mildly spicy, restrained scent avoids overwhelming small spaces, yet still adds a pleasant note on damp evenings, making it suitable near seating where you want subtle fragrance rather than intensity, ideal for sensitive-nosed visitors. |
| Clay-soil border with improved drainage |
Placed in a slightly raised bed or backfilled hole with grit and compost, ISIDORA™ copes well in Irish gardens where heavier soils can stay wet, giving golden structure where other shrubs struggle, reassuring practically minded owners. |
| Large container on a sheltered doorstep |
Its compact frame and moderate spread allow successful container use in at least 40–50 litre pots, where consistent watering and feeding support repeat flowering, creating a welcoming, low-effort accent for space-limited balcony or doorstep residents. |
| Supervised family garden with routine care schedule |
This variety’s sensitivity to rust and other fungal issues means regular preventative spraying and good air circulation are needed, particularly in wetter, humid conditions often seen along the Atlantic coast during extended rainy spells, suiting engaged, learning gardeners. |

- Family-Focus – group three shrubs in a triangle near a seating area, combining them with airy grasses for movement and gentle colour – good for family gardens with informal gatherings

Modern shrub developed from a ‘Graham Thomas’ seedling by Biljana Božanić Tanjga at PhenoGeno Roses, Serbia; bred and introduced in 2018, with PhenoGeno as the initial distributor. |
| Growth and structural characteristics |

| Resistance and winter hardiness |
Hardy to approximately −26 to −23 °C (RHS H7, Swedish zone 4, USDA 5b); disease resistance is moderate to low, with particular sensitivity to rust, so regular protection and hygienic care are recommended. |
