Baby, it can be cold outside in Zone 5 during the winter! But the roots of all of these tough sages (Salvia spp.) listed here survive sustained frost and snow, then rise up again in the spring.
To minimize weed growth, the best defense is the good offense of dominating a flowerbed with sages. Although much research is yet to be done, it appears that Salvia plant chemicals and growing patterns deter weed growth. Mixing in an efficient groundcover sage that forms dense clumps of foliage -- such as the lush Adora Blue Meadow Sage -- makes it tougher for weeds to gain ground.
Here are brief profiles of some of our favorite, powerfully fragrant sages that tolerate cold and grow well in full sun to partial shade.
Adora Blue Meadow Sage (Salvia x superba 'Adora Blue') Zones 5 to 9.

Mid-summer through fall is a fine time for planting sages. Most of these plants likely won't bloom until next season. However, gardening is an act of faith in beauty to come. Don't hesitate to contact us for information and encouragement.
