How to Grow

Salvia nemorosa ‘New Dimension Blue’ should be planted early in the spring or early fall once major frost risks have passed. The key to success is ensuring excellent drainage; these plants thrive in average, dry to medium soils. While they tolerate drought, they prefer moist, gravelly, or sandy loams. Plant in a location receiving full sun, as insufficient light reduces flowering intensity and can encourage floppiness.

Watering should be consistent during establishment. Once mature, this Sage variety is highly drought tolerant, requiring supplemental watering only during extended, dry periods. Avoid overwatering, which can stress the root system and increase the risk of fungal issues. Fertilization is rarely necessary; rich soils often lead to leggy, less desirable growth.

Pruning is essential for maximizing the bloom period of Salvia nemorosa ‘New Dimension Blue’. Deadheading spent flower spikes encourages repeat blooming throughout the summer and possibly into the fall, provided regular moisture is maintained. If the plant becomes unsightly or floppy mid-summer, especially in humid conditions, cut stems back aggressively to the basal foliage. A harder cut after the main flowering has concluded will tidy the plant for winter preparation.

Landscape Uses

Salvia nemorosa ‘New Dimension Blue’ excels in traditional perennial borders, adding vertical interest without overwhelming neighboring plants due to its compact habit. Its intense violet-blue spikes provide a wonderful cool contrast against warmer reds, yellows, and oranges in cottage gardens or wild garden settings. Plant these Salvias in drifts for the most impactful display along paths or at the front of mixed borders.

Their reliability and low stature also make them excellent structural components in butterfly gardens, ensuring a constant source of nectar for pollinators. Because the foliage is aromatic when bruised, these plants are naturally avoided by deer. Furthermore, the compact nature of ‘New Dimension Blue’ makes it one of the best Salvias available for container gardening, providing reliable color all season.
