Whistler™ Late Iberis

Whistler™ Late is the 70086780 selection in Syngenta’s Whistler series of Iberis sempervirens. The breeder lists a mounding habit and an early- to mid-spring flowering period, and says its F1 seed line is uniform in habit and flowering. ## Site and season Syngenta gives a garden height of 15–25 cm, a width of 8–10 cm, and sun-or-shade exposure. NC State describes evergreen candytuft as a low groundcover for full sun or light shade, with small spring flowers; its guide lists border and edging use for the species.

NC State notes that Iberis sempervirens tolerates moist to slightly dry soils but declines in wet or poorly drained ground; it also recommends neutral to alkaline soil. ## Maintenance Shear lightly after flowering if needed to encourage new growth and keep the mound neat.
