An upright growing Rosemary, 'Alcalde Cold Hardy' is a very cold hardy selection with wide, olive green leaves and a mid-spring display of pale blue flowers. Drought resistant/drought tolerant plant (xeric).
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).
30-36" x 24-36" wide (cutting propagated). Alcalde Cold Hardy is very cold hardy, upright growing Rosemary found growing in a northern NM garden where it has withstood years of sub-zero winters and intense, high elevation summer sun. With its pale blue flowers and thick, olive- green leaves, this is a beautiful xeric landscape plant. Brought into cultivation by agronomist Charles Martin.

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.

All perennials and spring-planted bulbs are packaged to withstand shipping and are fully-guaranteed. Please open upon receipt and follow the instructions included.
Perennials and spring-planted bulbs are shipped at the proper planting time for your hardiness zone. Perennial and spring-planted bulb orders will arrive separately from seeds.
