Tropicals provide an instant impact upon installation, and enjoyment for the entire growing season.
'Black and Blue' Anise-Scented Sage starts blooming in July and continues until the first frosts. The showy flowers are a deep cobalt blue, set off by black calyces. They are produced in great numbers on long spikes above shiny green foliage. Like other large flowered Salvias, 'Black and Blue' is an amazing hummingbird and Sphinx Moth magnet. Give it plenty of room in the late summer garden, as it is a sprawler. With lots of mulch, Salvia 'Black and Blue' has been known to overwinter in Zone 6 and 7.
