Salvia 'Blue Monday' is a striking perennial plant known for its vibrant and abundant blooms. It features tall, slender spikes adorned with deep blue-violet flowers that create a stunning contrast against its dark green, aromatic foliage. Typically growing to a height of 18-24 inches (45-60 cm) and spreading to about 12-18 inches (30-45 cm) wide, 'Blue Monday' is a compact and well-behaved plant that fits nicely in garden borders, containers, or as part of a mixed planting. It thrives in full sun to partial shade and prefers well-drained soil. This Salvia variety is not only drought-tolerant once established but also attracts pollinators such as bees, butterflies, and hummingbirds, making it an excellent choice for eco-friendly gardening. Blooming from late spring to early fall, 'Blue Monday' offers a long-lasting display of color and is relatively low-maintenance, requiring minimal deadheading to encourage continuous flowering. It is hardy in USDA zones 4-9, making it suitable for a wide range of climates.
