Salvia lyrata 'Purple Knockout'

Purple Knockout lyre-leaf sage

Native to North America (cultivar)


Mainly grown for its rosettes of glossy burgundy leaves that transform to a deep purple in summer followed by red in the autumn, this native selection is the perfect substitution for non-native Ajuga.  Blue flowers appear in late spring and early summer - sometimes without petals, but despite they still attract a bevy of pollinators and butterflies.  Plants thrive in moist or dry soil as long as they are in sun to part shade and may self seed to produce a ground cover of plants 18" tall with a 12" spread.
