Salvia ‘Maraschino’ is a reliably cold-hardy salvia, the first red to reliably overwinter in our climate. (Good winter drainage is important.) A tiny plant grows over the summer into a 2’x2′ mass of red blooms. Hummingbirds and butterflies love them!
Look at that color!
Full sun, completely drought-proof once established. (I never water mine.) They detest soggy soil in the winter.
