| The American Rose Society accounced that a new plant hardiness zone map has been released by the USDA; the first zone changes in over 20 years. According to the map, I've moved from 6b to 7a. Although, I guess your location can vary your zone within a zone anyway, but I thought it was interesting..

| Mine went from 5a to 5b. That's only 5 degrees but when you're talking below zero temps I'm still preparing for the worst. |
|
| I went from 5b to 6b--never quite believed the 5b anyway, as my experiences never matched what the books said for our supposed zone. But my default Zone on here continues to be south z5 unless I change it for each new message, as the "Zone" link is broken and I'm not sure how else to change my default. |

| Sitting on the edge of 7a/7b. |
|
| It explains why I've never the problems with my China and Tea roses that other zone 6 gardens have had. I knew I was on the 7a border before, and 7a seems a lot more accurate to me in terms of hardiness. I guess adding a few more teas and chinas is now justified! ~Tammy |

| Wow, I'm up to an 8 |
|
| I just went in and changed my profile to show my new zone. Don't forget to do that if yours has changed! |
|
| Glad to see I'm in 7A now, instead of 6A or B, whatever it had been. This makes better sense to me based on my experience in recent years, but I was concerned about adding in plants which the zone chart previously said wouldn't work for me. Certainly opens up a whole new world of gardening! |

| Southern Ohio is now in the same zone as southern Michigan. Let me tell you, there is a difference. |
|
| Well the difference is that the weather in areas along the lakes are very much tempered and affected by them. That's why the eastern lakeshores of the Michigan are in warmer zones. I've known this for years as I have been able to grow plants that were at least a zone warmer than the previous maps said we were without any problems. This just confirms it. |

| I am now 8a - the small change does not have any practical implication to me as we are at risk for the occasional deep freeze. Whatever the average annual extreme temperature, we are still at risk of going down to -15 to -20 C and those are the important temperatures I need to keep in mind. It helps me to keep my ambitious, adventurous but futile plant selection tendencies in check. |
