S. nemorosa‘White Profusion’
Back in the 1990s , when I was planting my first cock-a-hoop garden , May Night salviawas the Perennial Plant of the Year , and I loved its long - hold up blooms and all the bees it brought to the garden , though it did sometimes flop over . later on , ‘ Caradonna ’ salvia ( S. sylvestris‘Caradonna ’ ) came on the panorama . Hardy to geographical zone 4 , its blooms last for weeks and bees absolutely swarm it . Both of these stalwart varieties are still available and well deserving planting . But you have more options !
Here are five to consider and why you might plant each one .
