Cilantro plants are grown from coriander seeds. The plant is related to the parsley plant, and cilantro is often referred to as Chinese parsley. The herb is commonly used in Mexican and Southwestern dishes often served in Texas. Cilantro prefers cool weather, so Texas gardeners must sow their coriander seeds in February to harvest in March through April. Because of the mild fall and winter weather in Texas, gardeners enjoy a second growing season suitable for cilantro: plant in October to harvest in November through December.
Rosemary plants develop into large shrubs that reach heights of 3 to 5 feet. The edible leaves are shaped like pine needles and have a very strong taste. The leaves are used in Mediterranean and Italian dishes and in teas. Rosemary plants like full sun and quick-draining soil like the sandy loam found in south Texas. Once the plants are established, they become drought resistant, which is ideal for the extended dry periods during Texas summers.
Like rosemary, sage plants grow to be large shrubs. Sage leaves are wrinkled and velvety. Sage has a mild flavor that lends itself to poultry--it is a common ingredient used for Thanksgiving recipes. Sage prefers well-drained soil; if your soil is clay-like, plant your sage on a hill so that excess water drains away easily. Once it is established, sage plants survive on infrequent rain water.
Mint plants have a cool flavor that goes well with summer dishes and beverages. Mint grows well in Texas if it is given a shady area in which to thrive. Be forewarned, however: mint is an invasive plant that will overtake a garden given the opportunity. Mint plants need to be corralled to keep from choking out other plants. Use borders buried 10 to 12 inches below the surface of the soil to keep the mint controlled.
