Perovskia 'Blue Spire'
Perovskia 'Blue Spire' is a drought-tolerant perennial shrub with silvery-green foliage that produces lovely spires of lavender-blue flowers. Growing up to three feet tall this variety of Perovskia has fine to medium-textured stems bearing long panicles of blooms in early summer. The flowers attract pollinators like bees and butterflies and provide lasting color in the garden. It prefers full sun, well-drained soil and low moisture conditions. Established plants need little attention and can be pruned in late winter to maintain a tidy shape. This heat- and drought-tolerant plant is perfect for containers, rock gardens, and sunny borders.

watering
Perovskia is a low maintenance, drought tolerant plant, and will only require occasional watering. When watering, ensure that you do so deeply, allowing the water to reach the roots. During the summer months, it is best to water once a week, ensuring the soil is thoroughly moistened. During winter, Perovskia may require less water and should be watered only when the soil is dry.
sunlight
Perovskia 'Blue Spire' requires 6 to 8 hours of direct sunlight daily. To get the best performance, it should be planted in full sun, meaning that it should receive at least 6 or more hours of direct sunlight each day. Partial shade is also acceptable, but it will not grow as vigorously. If it's not placed in an area with direct sunlight, it will receive less light and flowers may not produce.
pruning
Perovskia 'Blue Spire' should be pruned twice per year for optimal growth. Pruning should occur in late winter, just before new growth begins in the spring, and then again in mid-summer. The pruning in late winter should be more extensive, cutting back old stems to 8-10 inches just above the ground. This promotes vigorous new growth which will bloom the following year. In mid-summer, prune off spent flowers to keep the plant from going to seed and to promote more abundant blooms. Additionally, prune out any thin, spindly stems to prevent the plant from becoming too leggy.
