Planning your spring garden or patio plants? You might have limited space, and certainly should consider limiting water use, so I’ve got a few tips for choosing low-water herbs for your garden, kitchen window or patio.
The good news is that like many xeric plants we grow in New Mexico gardens, many herbs have their roots in the Mediterranean. They prefer well-draining soil and low water.
Rosemary (Rosemarinus officinalis) is the first herb that comes to mind, and is one of my favorites, both as an herb and as an ornamental. You can grow a small rosemary in a pot, keeping it trimmed (by cutting the tips and using the herb in recipes, of course) or grow a mounding or spreading form of the plant in your low-water garden. As an ornamental, rosemary has attractive foliage and blooms with light blue or pink flowers. It’s a tough herb that survives cold to about 15 degrees Fahrenheit. Just watch for overwatering and snow damage. If you get a heavy snow, try to knock the powder off your rosemary plant. Here’s a link to the Herb Society of America’s fact sheet on rosemary.
Thyme (Thymus) is another low-water favorite. Thymus vulgaris is the common shrubby herb, but several ornamental forms provide interest in the garden, and other flavors provide culinary variety. For example, lemon thyme is a favorite for marinades or sauces. I love to walk around our rock garden and rub my fingers on the leaves of our thyme shrub just to get a whiff of the scent, which is sort of a combination of earthy and salty. We use the dried leaves in several recipes and also enjoy the tiny, delicate lilac-colored flowers in summer. Thyme only needs water in the hottest zones and times of year.
Lavender (Lavendula) is a favorite Mediterranean herb, and we are experimenting now with several varieties. Our biggest mistake was to place the mail-ordered plants in the ground a bit early. The soil was not warm enough for the sun lovers. Lavender must have well-drained soil to prevent the roots from sitting in water. In New Mexico, French of Spanish lavender works much better than English lavender varieties. Be careful not to cut into the woody stems when trimming. Check with nurseries or catalogs for the best variety in your area and zone and for the purpose you want. I’ve used lavender in recipes, and have dried stalks of it in vases throughout my home just for scent and attractiveness. We’ll keep trying to improve our lavender-growing skills, and studying ideas for uses. Check out our Pinterest board for more on lavender.
Fennel (Foeniculum vulgare) needs full sun and most varieties require no watering. Although not as attractive as the other plants I’ve mentioned, fennel is a versatile herb and easy to grow. We haven’t planted any, but it’s popped up around our garden, presumably from seeds of past plants. The fern-like leaves do have some appeal, and birds love the seeds once they turn brown. With a flavor similar to anise, fennel is a stock herb for many breads and pickling mixes. Learn more from the Herb Society of America.
