The plant has taken well, but the flower buds are drying out before fully blooming. I'd really like to know the reason—is it getting too much sun?

Description
Dianthus 'Mrs Sinkins' is one of the most popular carnations among gardeners. This very old variety produces a profusion of white double flowers in late spring, which are distinguished by their feathery appearance. Their fragrance is so strong that a simple bouquet can perfume an entire room. It can easily be propagated by cuttings, meaning you can quickly create beautiful borders at a lower cost. It is a problem-free perennial. Perfect in well-drained soil in the sun. It is fantastic in borders, rockeries, or even in pots.
'Mrs Sinkins' belongs to the Caryophyllaceae family. It is an English cultivar dating back to 1868, resulting from cross-breeding between Dianthus plumarius, D. caryophyllus, and D. gratianopolitanus among others. Its growth rate is quite fast. Its adult size will not exceed 35cm (14in) in height with a spread of 40cm (16in) or more. This carnation forms a dense tuft, from which a profusion of 4 to 5cm (2in) wide double flowers with intensely and finely fringed petals emerge in May-June, carried at the end of well-budded stems. Its linear, glabrous, pruinose-looking, pointed, evergreen, and leathery leaves are a superb grey-blue colour throughout the year.
'Mrs Sinkins' is an elegant and prolific variety. It is ideal in borders, embankments, and dry rockeries. It brings undeniable charm to a garden design dominated by stone. This plant looks lovely above and between the stones of a wall or pavement, in a trough, or in a container. In borders, it can, for example, accompany muscari, small lavenders, catmints, or other flowering cushions such as helianthemums, silenes, Phlox subulata, and Erigeron karvinskianus. To evoke gardens of the past, one can plant a small border of these charming carnations at the foot of peony clumps and old roses. They adapt very well to cultivation in pots, in light soil.

Planting and care
Plant Dianthus 'Mrs Sinkins' in ordinary, permeable and humus-bearing, gravelly, rather chalky, dry to moist, and especially well-drained soil. Gravel-rich soil yields good results. In the ground, this plant is quite hardy, withstanding temperatures down to -15°C (5°F). It prefers a very sunny exposure. Lightly trim the clump after summer flowering to encourage a second bloom in September. In rich soil, trim part of the foliage with shears after flowering to maintain a dense habit. Apply a balanced fertiliser to poor soil in March. Divide the clumps every 3 years to rejuvenate those with bare bases. Propagate through layering or by taking cuttings.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
