Rosemary Corsican Blue


Rosmarinus officinalisvar.angustissimus Corsican Blue

Deep blue flowers and dark green foliage

Rosemary is a must have for keen cooks, an evergreen shrub with highly aromatic dark green leaves which give off a powerful scent especially when planted in full sun where this Mediterranean plant is happiest. Deep blue flowers stud the stems in May and sporadically through the summer.


Happiest in full sun, sheltered from cold winds. It has a relaxed habit so great for the edge of raised beds, also happy in a container.


Easy to grow in a well-drained soil but add some coarse grit to the planting hole if your soil is heavy and wet in winter. Harvest the young leaves as required. Use a good quality general purpose compost for container growing and raise the pot on 'pot feet' through the winter months to help with drainage.

Add the leaves to soups, stews, sauces, stuffing and salads. Particularly good with chicken, lamb and vegetable dishes. May also be used to flavour oils and bread.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Position the stake in the hole, on the side of the prevailing wind and drive it into the soil, to a depth of 60cm. The stake should be a third of the height of the tree, when planted. Remove the pot and position the plant in the hole close to the stake, with the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Use two tree ties to secure the stem to the stake. Water in well and keep well watered during the plant's first year. Check ties regularly and adjust them as the tree grows.
