A Fine-Textured Gold-Green Boxwood Alternative Thunderbolt Boxleaf Honeysuckle (Lonicera 'Thunderbolt') is a dense, fine-textured shrub with tiny glossy leaves that flush bright chartreuse-gold — a lookalike for boxwood that can be sheared into tidy edges, low hedges, and topiary shapes. It's grown for foliage, not flowers. In Minnesota it sits well beyond its comfortable hardiness range, so it's best enjoyed in containers or as a protected, microclimate planting rather than a reliable in-ground hedge in Edina, Woodbury, or Maple Grove.
