We had a hard freeze the other night. It went down to about 27 degrees. It seems interesting that the petunias never froze and are still blooming but the impatiens were zapped the first time it hit 32 degrees. Has anyone seen a chart that tells the lowest temperatures that various flowering annuals can tolerate? It would be nice to know what plants need to be covered up and which can survive a light freeze. Thanks for any help.
