This is one of my favorite combinations in the garden right now–the orange Leonotis (Lion’s tail), the fuzzy red Salvia confertiflora, and Salvia mexicana ‘Limelight,’ with its bright purple flowers in chartreuse calyces. All three start blooming in early summer and keep it up until winter. The flowers last a long time, and the three plants will weave into each other and form one brilliant mass. Also, they’ll put up with a little shade–mine are on the west side of the house. They reach about six feet in my garden, but they’re easy to cut back, too.
