Salvia nemorosa 'Caradonna'
Caradonna meadow sage
Garden selection; the species Salvia nemorosa is native to Europe and western Asia
Overview
Salvia nemorosa 'Caradonna' is Caradonna meadow sage (dark-stemmed salvia), an upright perennial growing 18-24 inches (45-60 cm) tall and 18-24 inches (45-60 cm) wide. Narrow dense terminal spikes 8-12 inches (20-30 cm) of deep violet-purple tiny tubular 2-lipped flowers on dark purple-black stems. Medium green lance-shaped textured (rugose) aromatic foliage. Square stems. In the mint family (Lamiaceae spp.). The dark purple-black stem color is the cultivar's defining trait — distinguishing 'Caradonna' from green-stemmed cultivars like 'May Night' (S. nemorosa 'May Night'). The narrow upright spikes are strongly vertical — the plant holds its form without staking. Six weeks of primary bloom (June-July) with a full second flush in September if sheared after the first flush. The dark stem color fades to brown in shade — requires full sun (6+ hours) for the darkest stems. Does not tolerate wet winter soil — crown rot in poorly drained clay is the primary limitation. Basal rosette is semi-evergreen. Deer-resistant. Drought-tolerant once established. Non-toxic. Zones 4-9. Full sun. Growth rate is moderate.
