Set of 3 or 6 Rosemary ‘Blue Winter’ Herb Plants (Salvia rosmarinus), Hardy Evergreen Culinary Shrub, Outdoor Garden Ready, 1 Litre Root-Ball

Salvia rosmarinus 'Blue Winter' is a wonderfully hardy, evergreen rosemary that thrives outdoors year round across the UK. Renowned for its aromatic, needle-like foliage and striking blue flowers, this versatile culinary herb is as beautiful as it is useful in the kitchen. Whether you are roasting lamb, infusing oils, or simply brushing past it on a garden path, the rich fragrance of Blue Winter rosemary is hard to beat.

This collection of three established 1 litre plants gives you instant impact, perfect for creating a fragrant rosemary hedge, filling a raised herb bed, or adding structure to a Mediterranean-style border. Blue Winter is noted for its excellent cold tolerance, standing up to harsh UK winters far better than many other rosemary varieties. Its upright, bushy habit makes it equally suited to containers, window boxes, balcony gardens, and patio pots.

In late spring and summer, the plants produce a generous display of vivid blue flowers that are highly attractive to bees, butterflies, and other pollinators, making this a valuable addition to any wildlife-friendly garden. Low maintenance, drought tolerant once established, and evergreen throughout the year, Blue Winter rosemary is an ideal choice for both beginner gardeners and seasoned growers alike.

• Water regularly after planting until established. Once settled, Blue Winter is drought tolerant and requires only occasional watering during prolonged dry spells.


• Trim lightly after flowering to maintain a compact, bushy shape and encourage fresh growth.


• Avoid heavy pruning into old, bare wood as rosemary may not regenerate from woody stems.


• Feed with a balanced liquid fertiliser in spring if growing in containers.
