gentian sage 'Guanajuato'


Salvia patens 'Guanajuato', commonly known as Gentian Sage, is a striking flowering perennial known for its vibrant blue flowers. The plant features bright green, heart-shaped leaves that have a somewhat wrinkled appearance with serrated edges. These leaves are lush and create a contrasting backdrop for the blooms. The flowers themselves are large, tubular, and often described as a deep, eye-catching azure or cobalt blue, which is much sought after in garden settings due to the rarity of true blue colors in the floral world. Gentian Sage blooms form on long, arching stems that rise above the foliage, creating a dramatic and showy display. The individual flowers are arranged closely, and they have a velvety texture with small, white centers that add to their ornamental appeal. When in full bloom, the plant presents a spectacular splash of blue that can serve as a focal point in gardens or landscapes. The floral display usually occurs during the warmer months, often starting in late spring and continuing until the first frosts of fall, attracting pollinators such as hummingbirds and bees to the garden.

  • water dropWater

    The Gentian Sage should be watered deeply but infrequently once established, as it thrives in soil that is moist but well-draining. Generally, watering every 7 to 10 days would suffice, ensuring that the top inch of soil dries out between watering. During hot summer spells or if planted in containers, the watering frequency might need to increase. When watering, aim for approximately 1 to 1.5 gallons of water per plant, being careful not to overwater, as this can lead to root rot.

  • sunLight

    Gentian Sage prefers full sun to partial shade conditions. It flourishes best in an area where it receives at least 6 hours of direct sunlight daily. Avoid deep shade locations, as this can lead to poor flowering and leggy growth.

  • thermometerTemperature

    Gentian Sage is frost-sensitive and thrives in temperatures between 50°F and 85°F. It can survive minimum temperatures down to 40°F for short periods, but prolonged exposure can be detrimental. The optimal growing conditions for this plant are warm days and cooler nights within this temperature range.

  • scissorsPruning

    Gentian Sage benefits from pruning to encourage bushier growth and more blooms. Prune in the early spring to remove any dead or frost-damaged stems and again after the first flush of blooms to promote a second flowering period. Pruning should be light, removing only about a third of the plant’s overall height.

  • circleLife cycle

    'Guanajuato' Giant Blue Sage (Salvia patens 'Guanajuato') begins its life cycle as a small seed which, when sown in moist, well-draining soil and given adequate warmth and light, will germinate and sprout into a seedling. As the plant grows, it develops a set of true leaves and a sturdy stem, entering the vegetative stage where it rapidly increases in size. This perennial then produces buds which open into striking, large, deep blue flowers, typically during the summer months, attracting pollinators such as bees and hummingbirds. After the flowering period, pollinated flowers will set seed, which can be collected for propagation or left to self-sow in the garden. During the autumn, as temperatures begin to drop, the above-ground parts of the plant may die back, with the roots going dormant through winter, especially in areas with colder climates. In spring, the plant will regrow from its rootstock to complete the cycle, or it may be propagated from rhizome divisions.

    • Propogation time

      Spring-Early Summer

    • Propogation: The most popular method for propagating Salvia patens ‘Guanajuato’, commonly known as Gentian Sage, is through seed sowing. Propagation is best done in the spring after the last frost when soil temperatures have warmed sufficiently. To propagate Gentian Sage by seeds, one typically sows them directly into well-drained soil or starts them indoors in a seed tray filled with a sterile seed starting mix. The seeds need light to germinate, so they are usually pressed gently onto the soil surface or covered with a very thin layer of soil. If starting indoors, seeds should be kept moist and at a temperature of about 70°F (21°C). Germination usually occurs within two to three weeks. Once the seedlings have grown sufficiently and have at least a pair of true leaves, they can be transplanted to their final location in the garden.
