To both of thank you so much. I finally am understanding the why's of the Sunset Zone system. It is a much better descriptor. Mine is a Mediterranean climate with very long growing season, but a very cool summer ( my max high last summer was 86ºF for just a few hours...we call that hot!!) . Summers have at least once an undesired frost (
), but knowingly one can protect if (not always) the forecast is accurate. I use the national met forecast, plus windguru, plus wunderground plus a climate disaster home committee meeting with my godson and finally pray...
We live off the land (13 yrs with my godson in charge) so we must be doing things right...
But actually your precise information Ann is invaluable. It really gives me a point for comparison. I always felt that the hardiness zone was an inadequate descriptor when compared to my site.
Since I also garden beyond roses, including many of your wildflowers, then a much better understanding of microclimates is essential. It also helps me much more to understand what others do or don't, so now I'm in the midst of trying to figure out where I would be placed. Perhaps closest is Sunset 9. I'm not sure though because of the cool summers.
