It mostly walker low catmint is in full bloom, it is been almost a month blooming. Pairing the blue with chartreuse is a real deal, beautiful, pop the color within dark green from the trees and lawn.
It is very low maintenance and drought tolerant, the only work I did to get this view, just cut back the last year growth on catmint in early spring, just leave about 1 inch above the base. I did different method to see how it survive during winter.
1. I cut it back in the fall after first frost
2. I cut it back in early spring
Both method are work, there is nothing different with the result. The catmint survive either way and still look gorgeous in the summer. It is hardy in zone 3.
