It was cold out there, but no evidence of damage to the floral buds.

Ouachita bud sliced open lengthwise after one night of 10 F, Feb 19, 2015. No damage evident.

Ouachita buds, from same field on second night, when temps were 10 again. No damage evident.

Last week, we had record low temperatures in parts of North Carolina. At a farm in western NC, near Shelby, a grower cut samples after two consecutive nights of cold temperatures. He brought me Ouachita because its buds were a bit more swollen than Navaho.

We saw this last year, the center of the Navaho bud is blackened. So, you need to look closely.

Navaho bud showing blackened center, this is damaged.
