Frequently Asked Questions

Is Rosemary 'Boule' upright or trailing?
Trailing. 'Boule' forms a low, arching mound that spills over walls, raised beds and pot edges, rather than growing into an upright bush.

Does trailing rosemary taste the same as ordinary rosemary?
Yes. The leaves have the same rich rosemary flavour and can be used fresh or dried with lamb, potatoes, bread and roasted vegetables.

Can I grow Rosemary 'Boule' in a pot?
Yes, it is excellent in large pots and window boxes where it can cascade over the edge. Use a gritty, loam-based compost and avoid overwatering.

Is Rosemary 'Boule' hardy in the UK?
It is hardy in most UK gardens when grown in full sun and very free-draining soil. Cold, wet winter soil is the main risk, so in exposed or heavy-soil gardens grow it in a raised bed, on a wall top or in a pot.

How do I prune trailing rosemary?
Trim lightly after flowering to keep it bushy. Avoid cutting back hard into old, bare wood, as it rarely regrows from there.
