Introduction & History

When David Austin named this rose in honor of Her Royal Highness Princess Alexandra, a cousin of Queen Elizabeth II and a lifelong patron of gardening charities, he chose one of his very finest creations to bear the royal title. Introduced in 2007, 'Princess Alexandra of Kent' produces sumptuous, deeply cupped, peony-like blooms of the warmest, most luminous pink, each one a masterpiece of petal arrangement that seems to glow from within. The flowers are unusually large for an English Rose, frequently exceeding 10 cm across, and are complemented by a rich, complex fragrance that evolves from fresh tea-rose notes to a deeper, more exotic lemon and blackcurrant character as the bloom matures. This is a rose that commands attention without demanding it, combining regal bearing with the generous, approachable spirit of its namesake. In gardens across the world, it has earned a devoted following for its sheer beauty and the emotional response it provokes in all who encounter it.

Breeding History

'Princess Alexandra of Kent' was bred by David Austin and introduced in 2007 under the registration name 'AUSmerchant.' Its detailed parentage has not been fully disclosed publicly, but it represents the advanced generation of Austin's breeding program, incorporating decades of selection for large bloom size, strong fragrance, disease resistance, and balanced growth. The rose was named with the personal approval of Princess Alexandra, who officially launched it at the Chelsea Flower Show. It has since received numerous awards, including the prestigious Glasgow Award for fragrance and awards from rose societies in Germany, Japan, and the United States, confirming its international standing as one of the finest English Roses ever created.

Flower Form & Fragrance

'Princess Alexandra of Kent' produces exceptionally large, deeply cupped, fully double blooms with 100+ petals, frequently reaching 10-12 cm across. The color is a warm, glowing pink with a luminous quality, slightly deeper at the center and softer at the outer petals. The peony-like bloom form is breathtaking, with petals arranged in concentric layers creating depth and visual richness. Blooms are borne singly or in small clusters on strong stems. The fragrance is outstanding and complex: opening with fresh tea-rose notes, then developing layers of lemon zest and blackcurrant leaf, classified by Austin as a traditional old-rose scent. It is strongly projecting and fills a room when used as a cut flower.

Garden Design & Uses

'Princess Alexandra of Kent' deserves a position of prominence in the garden where its large, luminous blooms and magnificent fragrance can be fully appreciated. Plant beside seating areas, along main walkways, or as the centerpiece of a rose bed. At 90-120 cm tall, it suits mid-border positions and formal rose gardens. The warm pink tones pair beautifully with silver-foliaged plants like Artemisia and Stachys, with blue companions like Nepeta and Perovskia, and with white flowers for a soft, romantic scheme. Groups of 3 plants create a stunning focal point. It also combines well with deeper-toned roses for a graduated pink display.

Growth Habit & Hardiness

'Princess Alexandra of Kent' forms an upright, rounded, moderately vigorous shrub reaching 90-120 cm tall with a spread of approximately 75-90 cm. The growth habit is well-balanced and bushy, producing strong, upright stems capable of supporting the large, heavy blooms without excessive nodding. Foliage is medium green, semi-glossy, and has good disease resistance. Leaves are of medium size with 5-7 leaflets. New growth emerges with an attractive reddish tint. Thorn density is moderate. The bush develops a pleasing, symmetrical shape with maturity and is well-proportioned for its bloom size. Deadheading promotes reliable repeat flowering.

Climate & Hardiness

'Princess Alexandra of Kent' is hardy in USDA zones 5-9, tolerating winter temperatures to approximately -20°C (-4°F). It performs beautifully in temperate maritime climates and adapts well to a range of conditions across Europe, North America, New Zealand, and cooler parts of Australia. Heat tolerance is moderate; in hot climates, afternoon shade helps prevent rapid petal drop. Rain tolerance is fair to good; the deeply cupped blooms can hold water, but the sturdy petals generally resist balling better than lighter-textured varieties. In humid climates, good air circulation helps maintain foliage health.

Seasonal Care Calendar

Planting & Container Growing

Plant in full sun (minimum 6 hours daily) in rich, fertile, well-drained soil with a pH of 6.0-6.8. This rose rewards generous soil preparation: dig a hole at least 50 cm deep and wide, incorporating abundant well-rotted manure or compost. For bare-root plants, soak roots and set the bud union 5-8 cm below soil level. Space plants 75-90 cm apart. Apply an 8 cm layer of organic mulch. The large blooms demand strong nutrition, so soil enrichment is particularly important for this variety.

Container Growing

'Princess Alexandra of Kent' can be grown in containers with attention to its substantial nutritional needs. Use a minimum 50-litre container with excellent drainage. Fill with a rich, loam-based compost mix (John Innes No. 3) with added perlite. Feed fortnightly with a liquid rose fertilizer during the growing season, supplemented by a slow-release granular feed at the start of spring. Water regularly and deeply; the large blooms demand significant moisture. Position in a sheltered spot where the fragrance can be enjoyed. Repot every 2 years. Feasibility rating: 3/5.

Seasonal Care & Pruning

Spring: Prune in early spring, reducing stems by one-third to one-half, cutting to outward-facing buds. Remove dead, weak, and inward-growing stems. Apply a generous dressing of rose fertilizer and thick mulch. Summer: Deadhead spent blooms to maintain continuous flowering. Water deeply twice weekly during dry spells. Feed in June and July with a balanced liquid fertilizer. The plant benefits from a foliar feed of seaweed extract monthly. Autumn: Cease feeding by September. Clear fallen leaves. Tidy the plant lightly but avoid pruning. Winter: Apply protective mulch in zones 5-6. Check for and remove any wind-damaged stems.

Common Mistakes to Avoid

1. Under-feeding this heavy-blooming rose, resulting in smaller flowers and reduced repeat flowering. 2. Planting in a windy, exposed site where the large, heavy blooms are battered and stems may snap. 3. Allowing water to sit in the deeply cupped blooms by overhead watering; always water at the base. 4. Pruning too lightly, which produces a tall, leggy plant that loses its rounded proportion. 5. Planting in shade, where the luminous pink color cannot develop its characteristic warm glow.

Propagation

'Princess Alexandra of Kent' is a patented David Austin cultivar; commercial propagation requires a license. Home propagation by softwood cuttings in June-July is possible but challenging, as the complex hybrid genetics can result in lower rooting success rates. Take 12-15 cm semi-ripe cuttings, treat with rooting hormone, and root under a humidity dome. Commercial propagation is by budding onto Rosa laxa rootstock. Layering offers an alternative for home gardeners. Seed propagation does not reproduce the cultivar true to type. Difficulty rating: Moderate to difficult.

Diseases & Pests

'Princess Alexandra of Kent' has good disease resistance. Black spot may appear during prolonged wet periods but is generally less severe than on older English Rose varieties. Powdery mildew can develop in late summer, particularly in crowded plantings with poor air circulation. Rust is uncommon. The deeply cupped blooms can occasionally develop botrytis in prolonged rain if not deadheaded promptly. Aphids are common on new growth in spring and are easily managed. Capsid bug damage may cause distorted shoot tips. Leaf-rolling sawfly and roseslug are occasional visitors. A light preventative spray program may be advisable in disease-prone areas.

Cut Flowers & Exhibition

The spectacular, deeply cupped blooms of 'Princess Alexandra of Kent' are among the finest English Roses for cutting. Harvest when the outer petals have unfurled but the center remains cupped, revealing the layered petal structure. Cut in early morning with stems 25-40 cm long. Strip lower foliage and condition in cool water. The complex fragrance fills a room magnificently. The warm pink color works beautifully alone or combined with white and cream flowers. Vase life is 5-7 days.

Collector & Exhibition Notes

'Princess Alexandra of Kent' is a premier exhibition and collector rose. Its enormous, perfectly formed blooms regularly win prizes in English Rose and fragrant rose classes at national and international shows. For exhibition, select blooms at the moment the full cupped rosette is visible with layered petals, before the center begins to open flat. The large bloom size is a significant competitive advantage. Transport carefully to avoid petal damage. Its royal naming, international awards, and consistent quality make it one of the most prestigious roses in any collection. Commercially available but universally coveted.

Comparison with Similar Roses

Compared to 'Gertrude Jekyll,' another iconic pink English Rose, 'Princess Alexandra of Kent' has larger, more deeply cupped blooms and a more complex fragrance, but 'Gertrude Jekyll' is more vigorous and taller. Against 'Gentle Hermione,' it has significantly larger flowers and a more complex scent, but 'Gentle Hermione' has slightly better disease resistance and a more compact habit. Versus 'Jubilee Celebration,' the color is warmer (warm pink vs. salmon-pink) and the fragrance profile is different (tea-lemon-blackcurrant vs. fruity).

Heritage & Conservation

As a recent, commercially successful cultivar, 'Princess Alexandra of Kent' faces no conservation concerns. It is prominently featured in the David Austin display gardens, the Royal National Rose Society gardens, and major public rose gardens worldwide. Its significance lies in representing the peak of English Rose breeding achievement in the early 21st century. The royal association adds a layer of cultural heritage that elevates it beyond ordinary horticultural significance, linking it to the broader tradition of royal patronage of gardens in Britain.

Cultural Significance

'Princess Alexandra of Kent' carries dual cultural significance: as a tribute to the British royal family's horticultural patronage and as a demonstration of the enduring global appeal of English garden roses. Its naming ceremony at the Chelsea Flower Show, the world's most prestigious horticultural event, placed it at the intersection of royalty, gardening tradition, and contemporary plant breeding. The rose has become a symbol of the David Austin legacy and is among the most photographed and discussed English Roses in international media and social media, introducing new generations to the pleasures of rose gardening.
