Gardeners' Notes:

Positive ABLivingscape On Jul 9, 2013, ABLivingscape from Atlantic Beach, FL wrote:

This is a go-to groundcover plant for our harsh coastal environment. Shows good salt, drought and humidity tolerance but seems to need better fertility than our sandy soils provide. Thinning occurs if water is withheld for extended periods. Flowering is profuse after cold winters but less so if winter is mild.

This is the best rosemary I know of for the desert. Stays green in the worst heat, and ignores the frost !

We tried another type of rosemary which was upright, but it never bloomed. Huntington Carpet blooms small but beautiful blue flowers (if it gets regular water) all winter ! Plus it's edible !

After trying various ground covers that couldn't handle the high heat on a west-sloping full sun area, we are going with this rosemary.

This is a great groundcover for hot, dry summer areas. It grows very quickly and branches will root to form new plants, but it is not invasive.

This is a beautiful prostate rosemary cultivator. It's very drought tolerant and grows quickly.

However, even though I've read sources stating its hardiness range to be zones 6-8, I lost two different plants two years in a row here in zone 8 where the rest of my rosemary plants fared fine with little to no winter damage. Both were first season plants growing in potting soil in whiskey barrels. When I lost the one the first winter I bought another the next spring, but that one too didn't survive the next winter.

It may be that the plants sensitivity is to our excessively wet winters rather than the temperature but while it's a fun one to try, it's not a guaranteed variety for western Washington. All the same, I think this variety is worth another try and will be trying it again in sandy, well drained soil to see if that makes the difference.
