Salvia
Salvia is a large genus, containing about 900 species. In our climate mostly common (evergreen) sage is grown for culinary uses. Also, very popular are those of subtropical origin that are used here as annuals with long flowering season, especially in public areas. We concentrate on herbaceous perennials which are not widely cultivated and we believe that there are species, hybrids, and varieties worth the job.Description of the plant:
Merleau Blue is a perennial flowering sage of compact habit. It forms dense clumps with 30-40 cm tall stems holding long spikes of hundreds of deep violet-blue flowers from June until September. The calyxes are light purple blue which makes a great effect even if the plant is not in full bloom. Leaves are mid green, narrowly ovate, wrinkled, and softly hairy. Cutting off stems with spent flowers will encourage new flowering.Sage will grow in almost any well-drained soil. For best results grow it in light, humus-rich, well-drained soil in full sun or light shade. It is perfectly hardy to about -34°C (USDA zone 4) and will grow in outdoor pots and throws, too.
