Salvia Indigo Spires


Description: Salvia 'Indigo Spires' is a vigorous and upright perennial that belongs to the mint family, Lamiaceae. It features elongated spikes of densely packed, tubular flowers that bloom profusely from late spring through fall. The flowers are a striking indigo-blue color with purple undertones and attract bees, butterflies, and hummingbirds to the garden. The foliage of 'Indigo Spires' is aromatic, with lance-shaped, gray-green leaves that provide a lovely contrast to the vibrant blooms.

Size: 'Indigo Spires' typically grows to a height of 3 to 4 feet (0.9 to 1.2 meters) tall and spreads of 2 to 3 feet (0.6 to 0.9 meters) wide at maturity. However, individual plants may vary in size depending on growing conditions, climate, and cultural practices. This salvia has a bushy and upright growth habit, forming a dense clump of foliage and flowers. It is well-suited for use as a focal point in garden borders, mixed perennial beds, or as a container specimen.

Best Growing Zones: Salvia 'Indigo Spires' is best suited to regions with warm, temperate climates and is commonly grown in USDA hardiness zones 8 through 11. It thrives in full sun exposure, receiving at least 6 to 8 hours of direct sunlight per day. 'Indigo Spires' is relatively tolerant of heat, drought, and poor soil conditions, making it well-adapted to hot and arid climates. However, it may benefit from afternoon shade in extremely hot regions to prevent heat stress and wilting.

Soil and Sun Requirements: Salvia 'Indigo Spires' prefers well-drained soil with good fertility and adequate moisture retention. It thrives in full sun exposure, which is essential for promoting vigorous growth and abundant flowering. Adequate sunlight also helps enhance the intensity of the flower color and promote compact growth. 'Indigo Spires' is relatively adaptable to a variety of soil types, including sandy, loamy, or clay soils, as long as they are well-drained and have good fertility.

Maintenance: Salvia 'Indigo Spires' is a low-maintenance plant that requires minimal care to thrive. Water regularly during the first growing season to establish a strong root system, then reduce watering to occasional deep soakings during periods of drought. Deadhead spent flowers regularly to promote continuous blooming and prevent self-seeding. Prune as needed to remove dead or faded blooms and to maintain the desired shape and size. 'Indigo Spires' may benefit from an annual application of balanced fertilizer in early spring to promote healthy growth and flowering.
