Rosmarinus officinalis 'Collingwood Ingram' (also known as 'Ingramii', or 'Benenden Blue') is a vigorous, evergreen shrub prized for its semi-upright to arching habit, aromatic foliage, and profuse, deep blue flowers. This distinctive rosemary forms a broad, mounding shrub with soft, needle-like, gray-green to dark green leaves that radiate from arching, semi-trailing stems, releasing a strong, classic rosemary scent when brushed. While aromatic, it is not considered the best choice for culinary use compared to other varieties. From late winter through spring, and often sporadically into summer, it produces an abundance of small, two-lipped, tubular, intense deep blue flowers that are highly attractive to bees, butterflies, and other pollinators. With its excellent tolerance for heat, drought, salt spray, deer, poor soils, and seaside conditions, as well as its versatile, semi-upright to semi-trailing habit, it is an outstanding choice for slopes, cascading over walls, low hedges, foundation plantings, containers, and as a sprawling specimen.
