Sun-loving and drought-tolerant, rosemary crops have fragrant green-grey foliage, but in addition open mainly blue flowers from springtime or winter. One cultivar, “Blue Spires,” with especially showy lavender-blue blossoms, has moved from a supporting part in the herb garden into a starring part in the flower border.
“Athens Blue Spires” is a patented rosemary cultivar selected in the University of Georgia Horticultural Division test gardens as one of Allen M. The Georgia of Armitage Gems. Armitage applied for the sole survivor of seedlings developed from a packet of seeds for a plant patent in 1998. Since its introduction, both vendors and growers usually shorten the title to “Blue Spires.”

Both cool and heat-tolerant, this cultivar grows nicely in U.S. Department of Agriculture plant zones 6 through 11, and Sun Set Zones 4 through 2-4. As is the situation for other crops with Mediterranean origins, cultivars that are rosemary will endure wind-swept, sea- areas however you like.
As well as using personal crops in herb gardens or several specimens in casual sunny, dry perennial borders, consider utilizing “Blue Spires” as a low hedge — to 3-foot-tall — or for topiaries or espalier.

Although suggestion-pruning to improve branching is generally un-necessary because of “Blue Spires'” self-branching habit, do prune to remove old-growth and to keep your plants in-bounds.
