clary sage, is a biennial or short-lived herbaceous perennial
just like hybrid foxgloves
The may flower in the 2nd year and die, they may flower yearly for a few years and then die.
Some even flower soooo much they exhaust them selves and die
If the winter weather is bad they may die...........you get the picture.
In a nutshell..............they will flower next year, and if you're lucky they will last another year or 2
