Liriope ‘Big Blue’ is a reliable, evergreen perennial prized for its lush, arching foliage and striking summer flower spikes. Its deep green leaves form dense, fountain-like clumps that provide year-round structure, while tall stems of vibrant lavender-blue blooms rise above the foliage from mid to late summer. These long-lasting flowers add color and texture, followed by glossy black berries in fall that add another layer of visual interest. Versatile and dependable, Liriope Big Blue thrives in a wide range of landscapes, from borders and pathways to mass plantings and erosion-control areas.

This tough, adaptable plant performs well in full sun to deep shade and tolerates heat, humidity, and urban conditions with ease. It spreads gradually to form a lush carpet that suppresses weeds and stabilizes soil, making it an excellent groundcover choice. Its neat growth habit and evergreen foliage also make it a great option for foundation plantings, woodland gardens, and mixed perennial beds. Low-maintenance, resilient, and visually appealing across all seasons, Liriope Big Blue is a dependable choice for both beginners and experienced gardeners seeking lasting beauty.
