Complete Plant Information
Overview
Salvia nemorosa ‘Caradonna’, commonly known as perennial Sage, is celebrated in gardens for its exceptionally erect spikes of deep blue-violet flowers. This cultivar provides significant vertical interest, rising sharply above the foliage mound throughout the prime growing season. It is a hardy, low-maintenance centerpiece that thrives where many other perennials might struggle.
As an herbaceous perennial, this variety of Salvia nemorosa forms a neat, woody-based clump, prized for its dark purple stems that accentuate the vibrant summer blooms. It is highly attractive to essential pollinators, offering excellent value in butterfly and cottage gardens alike. Gardeners appreciate the reliability and drought tolerance once established.
The structure provided by Salvia nemorosa ‘Caradonna’ is fantastic for mass plantings along borders. Providing full sun and average, well-drained soil sets the stage for consistent performance from late spring well into autumn. Deadheading encourages the sporadic rebloom that keeps this favorite Sage looking fresh.

How to Grow
Plant Salvia nemorosa ‘Caradonna’ in spring or fall, ensuring it receives full sun exposure for the best flower production and strongest stems. This Sage variety adapts well to average soil, but excellent drainage is crucial; it prefers gravelly or sandy soils over heavy, water-retentive clay. Good planting location selection minimizes potential summer floppiness.
Care for this perennial is straightforward. It thrives with dry to medium water needs, establishing drought tolerance once mature, though regular moisture helps encourage repeated blooming later in the season. Fertilizing is rarely necessary; over-enriching the soil can lead to weak growth and flopping.
Pruning dictates the display. Deadhead spent flower spikes regularly to stimulate new blooms throughout summer and into fall. After the main flowering period concludes, or if the plant begins to look unsightly due to summer heat or humidity, cut the stems back hard to the basal foliage mound. This hard cut encourages fresh growth for the remainder of the season.
Landscape Uses
Salvia nemorosa ‘Caradonna’ excels when integrated into perennial borders, providing necessary upright structure among lower-growing companions. Its dark stems and vibrant flowers make it an excellent accent plant when grouped together, creating significant visual impact. Consider using this Sage in cottage gardens where its informal yet commanding spires blend beautifully with roses and ornamental grasses.
Due to its excellent drought tolerance and ability to handle air pollution, this variety of perennial Sage is ideal for planting along pathways or in the front or middle areas of sunny mixed borders. It pairs beautifully with silver-foliaged plants or silvery-leafed companions that complement the cool tones of the blue-violet flowers. Ensure adequate air circulation to mitigate potential fungal issues.
