Picea glauca 'Mac's Gold' is a striking dwarf evergreen conifer known for its vibrant golden-yellow new growth, which contrasts beautifully with the older green needles. This slow-growing cultivar of white spruce forms a compact, irregular pyramidal to globose shape, adding a bright accent to gardens, especially in spring when the fresh golden foliage emerges. Over time, the foliage gradually deepens to a soft green while retaining a golden hue in shaded areas. Its dense branching and fine texture make it a standout specimen in rock gardens, mixed borders, or as a focal point in small landscapes.
