SKU: 00840369421708 Spice Island Rosemary (Salvia rosmarinus 'Spice Island') in 3.5 pots

Plant Features & Growing Information

• Growth Habit: Upright, bushy, evergreen perennial herb with sturdy, woody stems and dense, aromatic, needle-like foliage. Typically reaches 24–36 inches tall and 18–24 inches wide at maturity. Growth is moderate to vigorous, forming an attractive, naturally rounded shrub.

• Bloom Color: Produces small, delicate blue to deep blue-violet flowers along the stems, primarily from spring through early summer. In favorable climates, occasional additional flowering may occur in fall.

• Fragrance: Exceptionally fragrant foliage releases a strong, refreshing, pine-like aroma with warm, woodsy, herbal undertones. Its fragrance becomes especially noticeable when leaves are brushed, crushed, or harvested. Flowers have a mild herbal fragrance.

• Fruit Flavor: Not grown for edible fruit. Rosemary produces tiny, dry, nutlet-like fruits containing seeds. These have no significant culinary value. The edible leaves provide a bold, savory flavor with notes of pine, citrus, cloves, and nutmeg.

• Culinary Uses: Highly valued as a premium culinary rosemary variety. Fresh or dried leaves are excellent for seasoning chicken, lamb, pork, beef, fish, roasted potatoes, vegetables, soups, stews, breads, and marinades. Sprigs can be used to infuse olive oils, vinegars, and herbal butters. Mature, sturdy stems may also be used as aromatic grilling skewers. The edible flowers can be used sparingly as garnishes.

• Medicinal Uses: Rosemary has a long history of traditional herbal use for supporting digestion, concentration, and general wellness. Its leaves contain naturally occurring aromatic compounds and antioxidants, including rosmarinic acid. Rosemary is also commonly used in herbal teas, aromatherapy, and cosmetic preparations. However, medicinal benefits are not fully established, and concentrated rosemary essential oil should not be ingested without professional guidance.

• Possible Toxicity to Pets or Humans: Generally considered non-toxic to cats and dogs and safe for human consumption in normal culinary quantities. Excessive consumption may cause digestive discomfort. Concentrated rosemary essential oils are significantly more potent than the culinary herb and may be harmful to pets or humans if improperly used. Some individuals may experience skin irritation from direct contact.

• Wildlife & Pest Resistance: Generally deer- and rabbit-resistant due to its strongly aromatic foliage. Its blue flowers attract bees, butterflies, and other beneficial pollinators. Typically resistant to many common garden pests, although aphids, spider mites, whiteflies, and mealybugs may occasionally appear. Good air circulation and proper watering help prevent fungal diseases and root rot.

• USDA Planting Zones: Best suited for USDA Zones 8–11 as an outdoor evergreen perennial. May survive in protected locations in Zone 7, particularly with excellent drainage and winter protection. In colder regions, grow as an annual or in containers that can be brought indoors before freezing temperatures.

• Sun Preferences: Thrives in full sun, requiring at least 6–8 hours of direct sunlight daily for optimal growth, fragrance, and flavor. Tolerates light partial shade, but insufficient sunlight may result in weaker growth and reduced aromatic intensity.

• Drought Tolerance: High once established. Spice Island Rosemary is well adapted to hot, dry conditions and requires relatively little supplemental watering after its root system develops. Young plants benefit from regular watering during establishment. Allow the soil to dry slightly between waterings, as excessive moisture can cause root rot.

• Soil Preferences: Prefers loose, sandy, rocky, or loamy soil with excellent drainage. Performs well in moderately fertile soil with a slightly acidic to alkaline pH. Avoid heavy, compacted clay and locations where water accumulates. Raised beds are particularly beneficial in areas with poorly draining soil.

• When to Prune: Light pruning can be performed throughout the active growing season, particularly in spring and early summer. Major shaping is best completed after the primary flowering period. Avoid heavy pruning in late fall or winter, especially in colder climates.

• How to Prune: Regularly harvest or trim the tender green stem tips to encourage branching and maintain a compact, bushy appearance. Remove dead, damaged, or weak branches as needed. When shaping, trim approximately one-third or less of the current green growth, avoiding cuts into old, leafless woody stems, which may not produce new shoots. Frequent light harvesting helps maintain an attractive shape while providing fresh herbs for cooking.

• Harvesting: Harvest sprigs as needed once plants are established and actively growing. For the best flavor, collect healthy stems in the morning after dew has dried. Leaves can be used fresh, air-dried, or frozen for future culinary use. Avoid removing more than one-third of the plant at a time.

Planting Instructions from a 3.5" Pot into the Ground

• Best Planting Time: Plant in spring after the danger of frost has passed and soil temperatures have warmed. In warmer climates, early fall planting is also suitable, allowing roots to establish before winter.

• Choose a Location: Select a location receiving 6–8 hours of direct sunlight daily with excellent drainage. Raised beds, herb gardens, rock gardens, and sunny borders are excellent planting locations.

• Prepare the Soil: Loosen the surrounding soil and remove weeds, rocks, and debris. If the soil is heavy clay or retains excessive moisture, plant in a raised bed or mound to improve drainage. Avoid excessive organic amendments that retain moisture around the roots.

• Dig the Hole: Dig a hole approximately twice as wide as the root ball and no deeper than the root ball itself.

• Remove from the Pot: Carefully slide the Rosemary plant from its 3.5-inch nursery container, supporting the root ball to minimize disturbance. Gently loosen tightly circling roots to encourage outward root development.

• Position the Plant: Place the plant in the hole with the top of the root ball level with or slightly above the surrounding soil. Avoid burying the crown or lower woody stems, as excessive moisture around the base can encourage rot.

• Backfill: Fill the hole with the original soil, gently firming it around the roots to eliminate large air pockets without excessively compacting the soil.

• Water Thoroughly: Water deeply immediately after planting to settle the soil around the roots. During the first several weeks, water when the upper 1–2 inches of soil begin to dry. Gradually reduce watering frequency as the plant becomes established.

• Spacing: Space plants approximately 18–24 inches apart to accommodate their mature width and provide adequate air circulation.

• Mulching: Apply a light layer of gravel, small stones, or coarse organic mulch around the planting area to help regulate soil moisture and suppress weeds. Keep mulch several inches away from the main stems to prevent excessive moisture buildup.

• Fertilization: Rosemary generally requires minimal fertilizer. If needed, apply a light application of balanced, slow-release fertilizer in spring. Avoid excessive nitrogen, which can encourage soft, leafy growth and reduce the concentration of aromatic oils.

Overwintering & Seasonal Care

• Zones 8–11: Typically remains evergreen throughout winter. Ensure excellent soil drainage, as cold, saturated soil can damage roots. Protect young plants during unusually severe cold snaps.

• Zone 7: Plant in a sheltered, sunny location with excellent drainage, preferably near a south-facing wall. Apply light winter protection during extended freezing weather. Survival is not guaranteed during severe winters.

• Zones 6 and Colder: Grow Spice Island Rosemary in a container that can be moved indoors before temperatures drop below freezing. Place it near a bright, sunny window or under supplemental grow lights.

• Indoor Winter Care: Maintain cool to moderate indoor temperatures, provide strong light and good air circulation, and water only when the upper portion of the soil begins to dry. Avoid overwatering, which is a common cause of winter decline.

• Winter Pruning: Avoid severe pruning during winter dormancy. Remove damaged or dead growth in spring once new growth begins.

• Spring Transition: Gradually acclimate overwintered indoor plants to outdoor sunlight and temperatures before returning them to the garden after frost danger has passed.

Additional Growing Tips

Spice Island Rosemary is particularly well suited for culinary herb gardens, Mediterranean-inspired landscapes, low hedges, and patio containers. Its upright growth habit makes harvesting convenient, while its evergreen foliage provides year-round ornamental interest in warmer climates.

For the healthiest plants and most flavorful harvests, prioritize abundant sunlight, excellent drainage, moderate watering, and regular light pruning. With proper care, Spice Island Rosemary can provide years of fragrant foliage and delicious culinary harvests.
