New zone map unveiled

The USDA has unveiled it's new hardiness zone map, and it's now interactive!  No more staring at a tiny map and guessing, especially when you are near the border between 2 zones.  Enter your zip-code and voila!  You can also zoom in.  Nice and handy.  And based on 30 year data the trend is slightly warmer zones, which I agree with.

  1. Thanks for posting this... all my suspicions have been confirmed and now that I am officially zone 5a, I can start buying and fretting over 6a plants!!

  2. Definitely. I'm sure you can find a 6a microclimate in the yard easily enough. Proper soil prep and winter mulch will go a long way to overwintering plants.

  3. I've been looking at that map and wondering what it really means all weekend! Looks like, due to a bit of heat-island effect, I'm actually 9a now...which is so weird! I can't help but feel a little guilt...I'm the only Portlander I know who doesn't even come close to pushing the zonal boundaries (mostly 8b around town). I doubt I have anything planted over zone 7! Is there such a thing as inverse zonal-denial? Either way...I think I have a little Zonal Guilt ;-)

  4. Scott, you have such a HUGE plant pallet to choose from for Portland that you really don't need to feel guilty about not pushing boundaries. That and I don't think anyone cares, your gardens are beautiful! Although you're now z9a, there are a number of really great plants that won't grow there because the climate is TOO mild. You just don't get warm enough in summer for some of them.

  5. I'm wondering if this might be the fellow whose list I saw some years ago regarding Magnolia acuminatas...
