Crimson & Emerald & Sky Blue

Crimson is the rose — the deep vivid crimson of the most celebrated deep-crimson rose varieties at Chelsea: 'Tuscany Superb' (a Gallica rose — Rosa gallica — approximately 1820, one of the oldest cultivated rose varieties still in widespread cultivation, characterized by a deep vivid crimson semi-double flower with prominent golden stamens and a strong perfume — it is named for the Italian region and suggests the deep crimson of the Tuscan landscape and its historic rose cultivation); 'Crimson Glory' (Hybrid Tea — developed by Wilhelm Kordes in Germany, 1935, one of the most celebrated and most influential rose cultivars of the 20th century — characterized by a very deep, velvety crimson flower with an exceptionally strong, classic rose perfume, though susceptible to mildew on its typically dark leaves); and the deep crimson of 'William Shakespeare 2000' (David Austin rose — Rosa 'Ausromeo' — 2000, one of David Austin's most celebrated deep-crimson English Roses, named for the poet-playwright and characterized by densely petalled quartered-rosette flowers in the most vivid deep crimson). Emerald is the Chelsea turf — the vivid jewel-green of the most precisely prepared and most intensively maintained horticultural turf in the world. Chelsea exhibitors preparing a 'show garden' (the largest category of Chelsea exhibits — full-scale garden installations evaluated against a published criteria list by RHS judges) typically begin turf preparation 12-18 months before the show: seeding a specific fine-grass turf seed mixture (typically composed of fine fescues — Festuca rubra subspecies and Chewings fescue — and bent grasses — Agrostis species — in carefully selected proportions that produce the finest texture and the most vivid green without the tendency to yellow under stress), overseeding multiple times during the growing season, treating with precisely calibrated nitrogen-phosphorus-potassium fertilizer regimes (typically applied as liquid feed at weekly intervals during the growing season), and maintaining at a cut height of approximately 5-8 mm for the final weeks before the show. Sky Blue is the English May sky — the specific airy, pale sky blue of a clear English May day over the Chelsea grounds. The Chelsea Flower Show (held in the last week of May — typically the Monday to Saturday of the last full week of May, though the precise dates vary year to year) enjoys the specific quality of English late-spring light: the sun is at a declination of approximately +21° to +22° N (approaching the summer solstice), providing long hours of soft, diffuse daylight (approximately 16 hours from sunrise to sunset in London at late May), with a characteristic sky color that is specifically the pale, luminous, slightly hazy blue of the English late spring — not the deeper, more saturated blue of Mediterranean summer skies, but the most characteristically airy and most quintessentially English sky blue.
