Salvia pratensis is a woody-stemmed perennial that produces sticky spikes of deep violet or, rarely, white to pink flowers. It blooms from early summer to autumn. It has wrinkled leaves and forms an upright clump 3 feet tall by 1 foot wide.
Salvia pratensis, the meadow clary or meadow sage, is a species of flowering plant in the family Lamiaceae, native to Europe, western Asia and northern Africa. The specific epithet pratensis refers to its tendency to grow in meadows. It also grows in scrub edges and woodland borders. Salvia pratensis is an herbaceous perennial forming a basal clump 1 to 1.5 m (3.3 to 4.9 ft) tall, with rich green rugose leaves that are slightly ruffled and toothed on the edges. The stems have four edges and are clad in glandular and soft hairs. Salvia pratensis is native to Europe, western Asia and northern Africa where it grows in meadows, fields, banks and rough places. It has become naturalized in many parts of the United States, and is considered a noxious weed in the state of Washington.
The plant can be grown in the areas with the lowest winter temperatures of -40° to -30°F (-40° to -34°C).
Here’s a handy guideline: increase pot size by 2.5-5 cm (1 to 2 inches) in diameter for plants that are growing in pots 25.4 cm (10 inches) in diameter or less. For larger plants, those growing in pots greater than 10 inches in diameter, increase the pot size by 5 or 7.62 cm (2 or 3 inches) in diameter.
