Plants that Survived 9° in My Zone 8a Winter Garden & Plants I Added in January

After having lived in New Jersey for several years, I am back in Mississippi, and I am in awe of all my garden plants that were not phased by January’s brutally cold weather. In spite of the fact that the temperature dropped down to 9° this past month, several of my plants are still growing strong.

Are Roses Evergreen?

I am especially impressed with how my roses fared the cold weather. In my experience, Roses are semi-evergreen in Garden Zones 7 and above, but I live in a slightly warmer area now. The roses that I have allowed to grow since spring were not phased by the 9° temperature I experienced in Mississippi Garden Zone 8a during  January.

Very Old Garden Plant – Probably Dates Back to Medieval Europe

Because the ground was frozen last week, I have postponed planting my Variegated Iris Pallida until today. But I planted some non-variegated Pallida the week before the hard freeze, and those starts have remained green.
