Salvia × jamensis 'Nachtvlinder' - Velvet-like plum-purple petals form hooded flowers over a long period in summer and autumn. Fully hardy in freely draining soils, this bushy shrub will become drought tolerant once established.
Black and Blue Salvia ~ I love this Salvia, it grows quite tall and Hummingbirds love it. It's an annual up here in Michigan, sometimes it will come up again but I usually have to buy new plants every Spring.
Stachys officinalis 'Hummelo' (salvia) -- This is a clump-forming perennial, which is mainly grown for the rose-lavender flowers which appear in summer. These flowers are held on upright spikes above the rosettes of dark green leaves and act as a magnet for bees. It provides great groundcover which is ideal for filling gaps at the front of the border.
