Chartreuse on the Loose Catmint (Nepeta ‘Chartreuse on the Loose’)

Chartreuse on the Loose Catmint (Nepeta ‘Chartreuse on the Loose’) is a unique and eye-catching perennial known for its vibrant chartreuse-yellow foliage paired with soft lavender-blue flowers. This striking combination provides season-long contrast in sunny landscapes, making it a standout choice for borders, edging, and mixed perennial plantings.

Unlike traditional catmint varieties that are primarily valued for their blooms, this selection offers strong foliage interest from spring through fall. The bright yellow leaves help illuminate garden spaces and pair beautifully with darker foliage plants and bold flowering perennials such as salvia, echinacea, and ornamental grasses. In early to mid-summer, spikes of soft blue flowers emerge, attracting pollinators including bees and butterflies.

In Alberta, Chartreuse on the Loose performs best in full sun and well-drained soil. It is drought-tolerant once established and thrives in hot, dry conditions, making it an excellent choice for Prairie gardens and low-water landscapes. Its compact, mounded habit keeps it tidy and manageable, requiring minimal maintenance throughout the growing season.
