When it comes to choosing a hardy rosemary variety, there are a few options that stand out. Two varieties that are particularly known for their cold-hardiness are ‘Blue Winter’ and ‘Hill Hardy’.
‘Blue Winter’ is a great choice for those looking for a cold-hardy rosemary. This variety has an upright growth habit and can form shrubs up to 1m tall. The foliage of ‘Blue Winter’ is a beautiful blue-green color, which adds a touch of elegance to any garden. The light blue flowers that bloom on this variety are also quite lovely. I have personally grown ‘Blue Winter’ in my garden and have found it to be incredibly resilient, even during harsh winters.
Another hardy rosemary variety is ‘Hill Hardy’. This variety can grow up to 1.2m tall, making it slightly taller than ‘Blue Winter’. The flowers on ‘Hill Hardy’ are also light blue, but the foliage has a grey-green hue. I have seen ‘Hill Hardy’ used in landscaping projects and it has proven to be a reliable and hardy choice.
Both ‘Blue Winter’ and ‘Hill Hardy’ are excellent options for those looking for a rosemary variety that can withstand colder temperatures. They are known for their ability to survive freezing temperatures and still thrive.
If you are looking for the most hardy rosemary variety, ‘Blue Winter’ and ‘Hill Hardy’ are both great choices. They have proven their cold-hardiness and are reliable options for any garden or landscape.
