Sage (common), Salvia officinalis
$6 per plant in 9cm pot
Oh sage, I do so love you and all of your cousins!
Common sage is a woody perennial that likes a nice sunny dry spot, in winter this is most important (the dry factor). You really ought to have it during winter too as it is a wonderful tea to have if you have a cold or gargle for sore throats. Of course it has all its culinary uses to boot.. grow lots and dry before the summers end
Grows well in containers.
