Denim ‘N Lace Russian sage is our Plant of the Week this week. Russian sage is a great spreading perennial for the garden. It fills in areas quickly and nicely by rhizomes. The silver-blue flowers add attraction to the garden.
Russian sage is hardy from Zones 5 to 10. In colder winters, it will die back to the ground, but generally does not. Denim ‘N Lace grows 2 1/2 feet tall and 3 feet wide, while slightly spreading outward by rhizomes. Other cultivars grow from 2 to 6 feet tall.
The leaves of Russian sage are silvery-green-gray, adding contrast to the garden. The flowers arise above the leaves and are shades of lavender, purple, or gray-purple. I have seen numerous pollinators on the flowers, from bumblebees to hummingbirds. https://www.livescience.com/57509-bumblebee-facts.html
Russian sage grows best in well-drained soils, but grows very well in heavy clay soils. It is adaptable and can withstand heat and drought without complications.
I like to prune Russian sage down by 1/3 to 3/4 in early spring, since the plant blooms on new growth best. Pruning can be done easily with pruners, shears, or a string trimmer and blade.
I love Denim ‘N Lace Russian Sage because it is shorter than other cultivars and fits nicely in to landscapes. It is very hardy and has lovely blue-green foliage that stands out in summer and fall – Nadine Champlin, Landscape Designer at Prairie Place Designs
