Personally I measure up the last ten years of minimum temps I've experienced in my area, then consider the lowest on record in the last 50+ years and definitely put that in perspective with not-so-cold hardy plants. For example, we normally don't go below 18 degrees out here, which makes it that some plants I'm growing are fine as they're hardy to 15 degrees, but, I know we've gone below 18 more than once in the last 20 years, so, I always keep supplies around just in case a big/bad one hits. If freezes ever start going below 28 degrees, I start covering anything hardy to 15.

Let's face it - There's just some things you GOTTA grow even if your area isn't perfectly warm enough lol. Pineapple Guava, Chilean Guava, Jelly Palm, Date Palm, cold-hardy edible Bananas, Loquats - All not the most cold hardy things but will survive out here in most winters. They're just too good of plants to not take on the challenge with!
