From roughly October through May in Tucson, herbs that don’t tolerate high temperatures grow well. These include things like cilantro, parsley, dill, and caraway. When temperatures creep up, these herbs bolt, which means that they flower and then die. To keep these plants going next season, remove the winter herbs in May and save their seeds. Replace them with herbs that can tolerate the Tucson summer heat. Herbs that grow well in the heat include basil, lemon balm, lemon verbena, oregano, mint, and garlic chives. Mexican mint marigold—also referred to as Texas tarragon and winter tarragon—is a heat-loving version of tarragon that is well suited to Tucson’s summer climate.
Landscaping Herbs
Herbs that can grow year-round in Tucson are easily integrated into landscaping. A popular example of this is rosemary, which many people in the region use for groundcover in their landscaping. Germander (Teucrium chamaedrys) is another popular choice for this purpose, as is lavender.
If you opt for lavender, stay away from English varieties and look for French (photo at left) or Spanish lavender (lavender pink), which will be better suited to the climate in Tucson. Some summer herbs, such as lemon verbena and lemon grass, can be used for landscaping as well, if they are planted in protected areas and covered in the case of frost.
Arizona has two planting seasons—a cool season (September through mid-November) and a warm season (mid-February through March).
Cool-season annuals include cilantro (coriander), dill, German chamomile and garlic and; while basil, epazote and summer savory are warm-season annuals. Sep 21, 2021
