Trailing Rosemary
Irene Rosemary is a trailing cultivar bred for ornamental and culinary performance in warm climates, thriving in hardiness zones 8-10. Unlike upright rosemary varieties, this plant cascades gracefully from containers and walls, reaching 2-18 inches tall depending on how you train it. Its evergreen, aromatic foliage produces vibrant blue flowers from late winter through spring, attracting pollinators while delivering the classic rosemary flavor gardeners expect. Grow it in full sun and you'll have a fragrant, flowering herb that doubles as striking landscape architecture.

Irene Rosemary's trailing habit transforms how you can use rosemary in the garden. Rather than standing upright in a border, it cascades over walls and container edges, creating a fragrant waterfall of aromatic foliage and blue blossoms. The evergreen leaves stay productive year-round, while the spring blooms bring pollinator activity and visual interest when many gardens are still waking up. Its ability to perform both as a functional culinary herb and a ornamental trailing plant makes it distinct from conventional upright rosemary selections.
Irene Rosemary functions as both an ornamental and culinary herb. The fragrant evergreen foliage can be harvested fresh for cooking, infusing dishes with the robust, piney flavor rosemary brings to Mediterranean cooking, roasted meats, and herbal teas. Its trailing growth habit also positions it as a landscape plant for hanging baskets, cascading over raised beds, wall planters, and groundcover applications where you want fragrant foliage at eye level or tumbling downward. The blue flowers are edible and add visual appeal to salads and garnishes.
Harvest Irene Rosemary foliage year-round by pinching or cutting sprigs as needed for fresh use. The best flavor develops in the actively growing period from spring through early fall. Pinch stems just above a leaf node to encourage branching and maintain the trailing form. Fresh rosemary sprigs can be used immediately in cooking or dried for longer storage.
Prune Irene Rosemary lightly after the spring bloom cycle to shape the trailing habit and encourage branching. Remove any dead or frost-damaged growth in late winter before the main flush of new foliage. Light pruning keeps the plant fuller and more densely foliated; avoid hard cutbacks that remove too much established growth at once. Allow the natural cascading form to develop rather than forcing upright growth.
