Mexican Sage (Salvia mexicana 'Limelight'),

This has been a reliable, pest-free perennial with low water requirements. I have it growing in full sun, where it is also open to the elements of wind and cold. It freezes to the ground each winter and comes back in late February. It will grow to about six feet tall and six feet wide by late summer in my garden. The long bloom spikes consist of gorgeous electric blue flowers emerging from lime green calyxes. It will bloom from late summer to the first hard freeze. It attracts butterflies, hummingbirds, bees, and neighbors (for those showy blooms).
This salvia was discovered growing in Quertaro, Mexico by Robert Ornduff in 1978. It is also known as Lolly Jackson salvia as it supposedly was found growing in her front yard garden.
