How a humble herb became the ultimate multitasker for cooks and landscapers alike

The Gardener’s Secret Weapon
Every herb enthusiast knows the frustration: you want aromatic foliage for cooking, year-round visual interest, and a plant that won’t demand constant pampering. Most rosemary varieties force you to choose – until now.
Salem Rosemary (Rosmarinus officinalis ‘Salem’) breaks all the rules. This vigorous perennial delivers exceptional cold hardiness (surviving down to 0°F) while maintaining the heat tolerance that makes rosemary a Southern staple. Its distinctive greyish-blue foliage offers ornamental appeal from January through December, culminating in a spectacular display of violet-blue flowers when most gardens are still asleep.
“I’ve stopped buying supermarket rosemary entirely. My Salem plant provides fresh sprigs year-round and survived last winter’s freeze when my other herbs died.”
– Margaret T., Zone 7b gardener
