‘Flashing Light’ Pinks (Dianthus deltoides ‘Flashing Light’) bring a palette of pink to the garden. The foliage offers shades of green, best highlighted among different textures. The usual flowering period is June-October. At maturity, expect 15 cm in height and 30 cm in width, which makes it suitable for the front of borders and rock gardens.
Soil choice is essential for ‘Flashing Light’ Pinks: well-drained, sandy, calcareous. The preferred exposure is full sun to partial shade. After planting ‘Flashing Light’ Pinks, water enough to thoroughly moisten the root ball. Once established, allow the surface to dry between waterings and prioritize drainage, especially during mild spells. Keep a general spacing of 30 cm between plants; this helps maintain their shape and allows access for care. The indicated hardiness zone is zone 3, to be assessed according to your garden conditions.
Throughout the seasons, ‘Flashing Light’ Pinks benefit from timely care: remove spent flowers and avoid watering that leaves the crown soggy at the end of the day. The neck of the pinks should remain clear; the lower leaves do not tolerate a layer of damp mulch pressed against them. For plant associations, consider catmints, upright sedums, and yarrows in varieties with similar needs. By composing around its volume of 15 cm by 30 cm, you will preserve the visibility of its blooms (June-October) and allow for good air circulation between plants.
