Salvia guaranitica 'Black and Blue'

Another plant catching visitors eyes can be found on the south facing top terrace next to staircase five. Salvia guaranitica 'Black and Blue' is a vigorous, half hardy plant (although we have not protected ours during the winter) and has been flowering in this full sun position since the end of June. The upright spikes carry a mass of dark purple-blue flowers held on at their base by black calyx, a real stunner.
