Autumn Sapphire Sage
'Autumn Sapphire' Salvia is another wonderful introduction by one of our favorite garden writers - Lauren Springer Odgen - and the Denver Botanic Garden. This beauty comes into bloom in late summer, when a lot of other flowering perennials are starting to slow down - and continues blooming right up until frost. As the name suggests, flowers are a rich cobalt blue; complemented by finely-textured green leaves. Plants grow to 18" to 20" tall and wide, and are hardy down to zone 5. Like most other Salvias, they also are great pollinator plants and are deer resistent. For best results, leave all the stems up until spring to make sure it survives the winter wet, and then prune back when new leaves begin to emerge. 'Autumn Sapphire' performs best in well-drained soil in full, hot sun. Looking for some good companion plants? Consider pairing it with Solidago, Rudbeckia, Echinacea, or Gaura - or create a mixed planting of 'Autumn Sapphire' and ornamental grasses!
