Believed to be one of the tallest Dianthus, D. giganteus shares much in terms of looks with D. carthusianorum but is considerably taller. From May into June, small magenta-pink flowers open successively from tight clusters of red buds held high on willowy stems that rise above neat rosettes of slender, grass-like, evergreen foliage.
Never showy, this is a naturalistic perennial that draws you in and captivates. Ever since Cleve West showcased D. cruentus in his RHS Chelsea Flower Show garden in 2011, Dianthus have been growing in popularity — and deservedly so. Preferring a non-acidic, free-draining soil in full sun, they are perfect for weaving through a border, meadow or contemporary planting scheme, adding transparency and slow-burning pops of colour. Like many bulbs, they occupy little ground surface area but soar and flower between other plants without disturbing them. Bees and other pollinators love them.
