The silhouette of ‘Key Lime Pie’ Carnation (Dianthus ‘Key Lime Pie’) adds depth to garden compositions. Among its distinctive features: fragrant flowers. The foliage displays shades of green, to be highlighted among different textures. The usual flowering period is June-September. At maturity, expect 30 cm in height and 30 cm in width, which makes it suitable for use at the front of borders and rock gardens.
Successful cultivation of ‘Key Lime Pie’ Carnation begins with its location: full sun, in suitable soil (well-drained, rather light; avoid waterlogged areas around the crown). After planting ‘Key Lime Pie’ Carnation, water enough to thoroughly moisten the root ball. Once established, allow the surface to dry between waterings and prioritize drainage, especially during warm spells. A 30 cm spacing corresponding to its spread prevents having to move the clump in the first few seasons. The indicated hardiness zone is 5, to be assessed according to your garden's conditions.
To maintain the appeal of ‘Key Lime Pie’ Carnation after flowering, remove spent blooms and avoid watering that leaves the crown saturated at the end of the day. The carnation's crown should remain clear; lower leaves do not tolerate a layer of wet mulch pressed against them. For plant associations, consider yarrows, border salvias, upright sedums in varieties with similar needs. Keep its 30 cm height in mind to place lower plants on the correct side and allow the flowers to be visible during June-September.
