Rosmarinus officinalis Irene
Details12-24" tall x 4' wide (cutting propagated). This is a superior selection of Rosemary "Prostratus" discovered by Phillip Johnson. He spotted it as a volunteer seedling in a northern CA landscape. "Irene" has nice medium green leaves and a low mounding habit with branches that will trail over walls and containers. Its strong blue-violet flowers come into color in early spring and are the highlight of this plant as they are larger, bluer and more profuse than any other trailing Rosemary. Fantastic for pots and hanging baskets! (cv:Renzels' P.P 9124)

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).
