Description
Rosemary (Salvia rosmarinus)
No garden or kitchen is complete without Rosemary, the ultimate Mediterranean multi-tasker. Renowned for its aromatic, needle-like foliage and intense herbal fragrance, this woody, evergreen perennial shrub is as tough as it is beautiful. From spring through summer, its dark green leaves are beautifully contrasted by dense clusters of delicate, nectar-rich blue, lilac, or white flowers that are an absolute magnet for bees and beneficial pollinators.
Rosemary is an exceptional, iron-clad performer. It is highly drought-tolerant, handles poor soils with ease, and stands up effortlessly to harsh coastal winds and intense summer heat. Whether grown as a culinary staple in a kitchen herb garden, trained into a low fragrant hedge, or allowed to cascade over a sunny retaining wall, Rosemary is a rewarding, low-maintenance asset to any landscape.

💧 Detailed Growing Conditions
Light: Full Sun (Non-Negotiable)
* Rosemary thrives on heat and requires Full Sun (at least 6 to 8 hours of direct sunlight daily).
* Planting it in the shade will cause the growth to become sparse, weak, and highly susceptible to pests and fungal diseases.
Water: Low (Extremely Waterwise)
* The Golden Rule: Rosemary hates “wet feet.” It has exceptionally low water requirements once established.
* Allow the soil to dry out completely between waterings. Overwatering is the quickest way to kill this plant, as its roots rot easily in stagnant moisture.
Soil: Poor, Sandy & Superbly Drained
* Prefers lean, sandy, rocky, or gravelly soils with a neutral to slightly alkaline pH
* It actually prefers poor soils; overly rich soil packed with organic compost will result in lush growth but will significantly reduce the concentration of aromatic essential oils.
* Excellent drainage is vital. If planting in heavy clay, you must amend the soil with plenty of coarse river sand or grit, or plant it in raised beds.
Maintenance & Pruning: Low Effort
* Pruning: To keep upright varieties bushy and prevent them from becoming woody and leggy, trim the plant back by about one-third after it finishes flowering. Avoid cutting back into old, bare wood, as it struggles to regenerate from old branches.
* Harvesting: Harvest sprigs at any time of the year by snipping the top 5–10cm of soft new growth.
🏡 Top Landscape & Retail Uses
* Culinary & Kitchen Gardens: An essential herb for roasting, grilling, and infusing oils. Place it near patios or kitchen doors for easy access.
* Waterwise & Xeriscape Gardening: Ideal for water-conscious landscapes, rockeries, and hot, dry embankments where other plants scorch.
* Fragrant Hedges & Edging: Upright varieties make excellent informal hedges along pathways, releasing their refreshing pine-like scent whenever brushed against.
* The Ultimate “Spiller” (Prostrate Varieties): Trailing rosemary is spectacular when allowed to drape like a green curtain over hot retaining walls, rock faces, or the rims of large patio pots.
* Coastal Tolerant: Highly resistant to salty sea air and strong coastal gales.
