I live in the blue zone (NW Oregon) but occasionally have frost as late as Memorial day.


i live in ocean springs/vancleave area of mississippi and was wondring about my zone and frost date. on your charts it looks like it could be either zone 8 or 9 and frost date looks like light orange or bright orange. would either be ok at guessing or is there a rule of thumb to go by????? thank you for taking the time to help. coleen

Hi coleen,
A lot of town are on the line. I live on the cusp of two zones, myself. If you want to use your zip code, try the USDA Hardiness Zone map.
Happy Gardening,

James Robinson

I planted bonnie bell vegetables last year&they grew beautifully. I had planted peppers red/yellow&orange according to directions but they all came up green! I was very dissappointed to say the least. They were delicious but they were green. I’m certain the tags were wrong but I don’t want the same thing to happen this year. What do I do or what can you to prevent the same situation?

Hi Diana,
If you feel as though your plants were mislabeled, please contact Customer Service. We want to ensure you are happy and successful in your garden. On some varieties, though, it takes (what seems like) forever for the fruits to turn from green to yellow or gold and red. I can understand the frustration if you never got the vegetable you intended. Please let us know. ~Mary Beth, Bonnei Plants


thankyou for updating our frost dates, you are my reality, i tell custumers this every day, and they look at me like i am an idiot.
