sage [Mystic Spires Blue]


Salvia Mystic Spires Blue, often known simply as Mystic Spires Blue, presents a striking appearance with lush green foliage that serves as a backdrop for its standout feature: long, slender spires of vivid blue flowers. The leaves are typically ovate to lance-shaped, with a slightly wrinkled texture and a tendency to be aromatic when crushed. The plant's deep blue flowers are densely packed in whorls around each spike, and these blooms are known for their ability to attract butterflies, bees, and hummingbirds who are drawn to their nectar-rich composition. Mystic Spires Blue is a hardy plant that holds its shape well, appearing bushy and full. It maintains a compact form, creating a neat and tidy appearance in garden settings. Its flowers have a tubular shape and are small and individual, but grouped together, they create a significant visual impact. This salvia variety blooms profusely, often from late spring through to the first frosts, providing a long-lasting display of color in gardens and landscapes. As a cultivated variety, Mystic Spires Blue is often praised for its improved characteristics over wild types, such as prolonged flowering time and a more manageable growth habit that makes it suitable for a range of garden applications, including borders, flower beds, and containers. The combination of its intense blue flowers and pleasant green leaves creates a contrasting tapestry that can enliven any garden space.

    Mystic Spire Salvia should be watered regularly, particularly during the growing season, to maintain consistent soil moisture. Allow the top inch of soil to dry out before re-watering to avoid overwatering. Typically, watering once or twice a week with about 1 inch of water should suffice, but this can vary based on climate conditions. During hot, dry spells, the plant may need extra water, but be cautious of waterlogging. During the winter, reduce watering frequency as the plant requires less moisture.

  • sunLight

    Mystic Spire Salvia thrives in full sun to partial shade, but the best flowering occurs in full sun. Choose a spot where the plant will receive at least 6 to 8 hours of direct sunlight daily. Avoid overly shaded areas as this can reduce blooming and cause the plant to become leggy.

  • thermometerTemperature

    Mystic Spire Salvia prefers warm temperatures and will perform best in a range with a minimum temperature of about 50°F and a maximum temperature below 90°F. The ideal temperature for this plant is between 70°F and 80°F. While it can survive light frost, it is generally considered a tender perennial, so protection or overwintering may be necessary if temperatures consistently fall below 50°F.

  • scissorsPruning

    Pruning Mystic Spire Salvia is essential for maintaining a bushy, healthy shape and encouraging more blooms. Prune early in the spring to remove any winter damage and again after the first flush of flowers has faded to encourage a second blooming. Deadheading, or removing spent flowers, can be done regularly throughout the growing season to promote continuous flowering.

  • circleLife cycle

    The life of Mystic Spires Blue Salvia ('Balsalmisp') begins with seed germination, where the plant emerges as a seedling under appropriate temperature and moisture conditions. Following germination, the seedling develops into a vegetative state, characterized by the growth of foliage and roots. As it matures, the plant enters the flowering stage, producing tall spikes of deep blue to purple flowers, which is when it is most attractive to pollinators such as bees and butterflies. After pollination, the flowers develop into small fruit which contain seeds, completing the reproductive cycle. If conditions are not favorable for seed dispersal and growth, the plant can also reproduce vegetatively through basal cuttings, allowing new plants to be cloned from the parent. At the end of the growing season, if the plant is not in a perennial climate it may die, but if it is hardy to the climate, it can enter a period of dormancy and regrow the next season from the root system.

      Spring to Summer

    • The most popular method for propagating the plant commonly known as Salvia Mystic Spires Blue involves taking softwood cuttings. This is typically done in late spring or early summer when the plant's new growth is just starting to harden but is still flexible. To do this, a gardener would select a healthy, non-flowering shoot and cut a 3 to 5-inch (approximately 7.5 to 12.5 cm) length, making the cut just below a node. The bottom leaves are removed, and the cut end is often dipped in rooting hormone to encourage root growth. The cutting is then inserted into a pot filled with a well-draining soil mix, ensuring that at least one node is beneath the soil surface. The pot is placed in a warm location with indirect light, and the soil is kept consistently moist until roots have developed, usually within a few weeks.
