Elevate your seasonal decor with Blue Spires Rosemary (Rosmarinus officinalis 'Blue Spires'), an aromatic evergreen shrub boasting silvery-green foliage and striking deep blue flowers from spring through summer. Reaching 4–5 feet tall with a narrow, upright habit, this drought-tolerant shrub doubles as a culinary gem—its sturdy stems serve as natural skewers for grilling, infusing dishes with robust flavor. Ideal for hedges or topiaries, it thrives in poor soils and resists deer, outperforming smaller rosemary varieties. Whether indoors or in gardens, its long bloom season and architectural form deliver year-round interest.
A live Blue Spires Rosemary reduces seasonal waste and offers a gift that grows. Its crisp, herbal fragrance enhances holiday ambiance indoors. Plant it outdoors after frost, and enjoy it as a fragrant screen or edible hedge. This living investment outshines disposable decorations for its longevity and culinary benefits.
Holiday Blue Spires Rosemary Care
Position the plant near a south-facing window for six hours of daily sunlight; supplement with full-spectrum LED lights placed 6–12 inches above if natural light is limited. Water only when the top inch of soil dries completely, and avoid high humidity to prevent mildew. Maintain indoor temperatures between 50–80°F, and rotate the pot weekly to encourage even growth. A pebble tray beneath the container adds subtle moisture without risking root rot.
Once nighttime temperatures stay above 50°F, acclimate the rosemary by gradually increasing outdoor exposure over 7–10 days. Plant in a sunny, well-drained location using sandy soil or a cactus mix for pots. Prune lightly after flowering to maintain shape, and harvest straight stems for grilling skewers. Whether in garden beds or patio containers, Blue Spires thrives with minimal care, rewarding gardeners with structure, fragrance, and flavor for years to come.
