Zagreb Coreopsis (Coreopsis verticillata 'Zagreb') welcomes the springtime sun with bright yellow, daisy like flowers that envelop its compact foliage. At just around 18" high and wide, its thread-leaf leaves stay neat and tidy, and make a great plant to add textural dimension as well as color. Zagreb Coreopsis craves the sun and makes a bright addition to the rock garden or perennial bed. Plant among broader leaved plants like boxwoods and euonymus for dynamic interest even when not in bloom.
