Many HERBS, such as Basil, Thyme, Cilantro, Parsley, Dill, Oregano, Sage, and I’m sure many others can grow at high elevation. Some of the herbs that are perennials in other locations are grown here as annuals, as they don’t survive the harsh winters.
Basil is transplanted outdoors AFTER the last frost, and must be harvested prior to the first frost, usually the beginning of September. Also grown in the greenhouse.
