Planting Guides

To get established in USDA zones 5 & 6, Rosemary must be planted in spring or early summer, not in the fall. Protect your new plants over their first winter or two in your garden. Cover each plant with a generous pile of clean straw or pine needles. This allows the plant's crown (junction of root and branches) to mature and obtain maximum cold hardiness.

We have an area in our landscape that's too extreme for most plants. The plants we purchased from High Country have always been the hardiest plants for tough spaces. I wanted a rosemary that could handle the freezing temperatures we get in this space. The plant is faring very well and we've been into single digits, it's outside uncovered. It will be awesome to have fresh rosemary year round. Great cultivar for the area. HCG has done it again!

have planted this rosemary for 3 years, i like it's color, form, fragrance, and flavor. has grown well for me as an herb garden annual, and container plant that is brought in for the winter. however i have not had one survive a zone 6 newengland winter yet, i may try and use a rose cone over one this winter for a lil added protection.but if you don't mind replanting it every year or bringing it in for the winter it is a great cultivar.

            Comments about High Country Gardens Rosmarinus officinalis Alcalde Cold Hardy:

            The rosemary was planted with other herbs in a large window box and was lovely for the summer. Wehave had a very cold February. Even though the "potting shed" where the herbs winter was heated, the temperature occasionally dropped below freezing. I think all three rosemaries, inluding the Alcalde got too cold. I am trying tobring them back--we'll have to see. It was a very strange winter.

              Q & A

              Suggested Companion Plants:

              USDA Hardiness Planting Zones

              To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

              • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
              • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
