What customers say
Customers overwhelmingly praise the Delphinium 'Blue Mirror' for its intensely vibrant, true blue coloration, which creates a spectacular garden focal point. The quality of the plants received is consistently high; reviewers report healthy, robust specimens that establish well. While the compact habit is appreciated for easier management, the primary point of friction involves value. Despite excellent performance and reliable perennial return once mature, some buyers feel the premium pricing does not fully justify the initial size of the starter plant. Overall, it is viewed as a high quality, high impact investment for gardeners prepared for its specific care requirements.
