Blue Lagoon Rosemary (Rosmarinus officinalis 'Blue Lagoon') is a vigorous, upright ornamental herb shrub producing an abundance of rich, deep blue flowers above densely packed, intensely aromatic dark green needle-like foliage — delivering one of the most vivid and deeply saturated flower colors available in any rosemary cultivar. This outstanding selection combines exceptional ornamental beauty with the classic, intensely resinous rosemary fragrance and culinary versatility that has made this beloved Mediterranean herb an essential plant in organic gardens, pollinator plantings, and aromatic landscape designs for centuries.

Grown from certified organic heritage stock, each plant arrives with a Professional Grade root system — dense, fibrous, and fully established for strong, vigorous first-season growth. Blue Lagoon thrives in full sun with excellent drainage and develops strong drought tolerance once established, excelling in water-wise, Mediterranean-style, fire-resistant, and low-maintenance organic landscape applications. Its upright, well-branched habit performs beautifully as a specimen plant, fragrant hedge, container focal point, pollinator garden anchor, and productive culinary herb — delivering year-round ornamental value, irresistible fragrance, and an abundance of fresh, organic culinary harvests in a single outstanding plant.

  • Exceptionally Deep Blue Flower Color — Produces some of the richest, most deeply saturated blue flowers of any rosemary cultivar available, creating a vivid ornamental display that stands out beautifully against the dark green aromatic foliage throughout the bloom season.
  • Year-Round Ornamental & Culinary Value — Intensely aromatic dark green foliage provides year-round structural interest and an ongoing supply of fresh organic rosemary for culinary use, while seasonal blue blooms deliver outstanding ornamental beauty.
  • Premier Bee & Pollinator Plant — Deep blue flowers are among the most attractive blooms available for honeybees, bumblebees, native bees, and beneficial insects — making Blue Lagoon Rosemary one of the most ecologically valuable herbs in the organic garden.
  • Drought Tolerant & Water-Wise — Develops strong drought resistance once established, thriving with minimal supplemental irrigation in water-wise, xeriscape, fire-resistant, and California-friendly low-water organic landscape applications.
  • Fragrant Structural Landscape Herb — Upright, well-branched habit provides year-round structural form and irresistible resinous fragrance as a specimen plant, fragrant hedge, container focal point, and essential culinary herb throughout every season.

These 4" healthy live plants thrive in full sun (6–8 hours daily) with excellent drainage — plant in well-drained to sandy or gravelly soil and water moderately until established, after which minimal supplemental irrigation is needed. Hardy in USDA zones 7–11, growing 3–5' tall with a spread of 3–4'. Deep blue flowers bloom in late winter to spring (February–May) with potential rebloom through the season in mild climates; prune lightly after bloom to maintain a tidy, productive form throughout the year.

We use expedited shipping policies to protect plant health and minimize plant stress in transit.  All plants are in transit for only 1-3 days. (This does not guarantee 3-day delivery as orders are not always packed and sent out on the day of your order.) We send out deliveries on a weekly schedule to ensure quick transit times, so your order may not be packaged and shipped until later in the week. For instance, we may hold shipments to avoid weekend delays that keep plants in transit for longer.

Additionally, any delays or damages in shipping are covered by our Healthy Plant Guarantee.
