Flowers and Herbs

Flowers: Store flowers in plastic or glass vases with warm water. Make sure to cut the stems diagonally before adding to the vase, and remove lower leaves so they don’t sit in water. Ideal temperatures range from 36-55° for individual flowers.

Herbs (including Chives, Thyme, Oregano, Rosemary, Basil, Parsley, Cilantro, and Dill): Cilantro, Dill, and Parsley can be refrigerated in a glass of water about an inch deep and covered with a plastic bag. Basil can also be stored in water but should not be refrigerated. Chives, Thyme, Oregano, and Rosemary can be wrapped in a plastic bag and stored in the warmest part of the refrigerator.
