when is blackberry winter
Blackberry winter is the name for a brief cold snap that usually happens in late spring, when wild blackberry bushes are blooming, often around early to midâMay in many parts of the U.S. South and lower Midwest.
What is âblackberry winterâ?
- It is a folk term for an unseasonably chilly spell after warm spring weather has already arrived.
- The name comes from the timing: it shows up when blackberry canes are leafing or blooming, their white blossoms standing out during a last taste of cold.
- People often treat it as a weather âsingularityâ â a recurring pattern that shows up in at least half of years.
When does blackberry winter usually happen?
- In much of Tennessee and neighboring Appalachian areas, it tends to fall in early to midâMay , often coinciding with the last frost threat of spring.
- Some regional descriptions place it as late as early June in cooler or higherâelevation spots, but still keyed to when blackberries bloom, not to exact calendar dates.
- Modern observations note that with warmer temperatures, these âlittle wintersâ are now running two to three weeks earlier than they did in the 19thâ20th centuries.
