Rosemary: How to Grow This Classic Garden Herb


Rosemarinus officinalis, or rosemary, is an evergreen, woody herb native to the Mediterranean region. An ancient herb steeped in myth and tradition, it’s well-known and beloved in the kitchen for its sweetly pungent leaves and flowers.

Growth of rosemary left in pots for too long can be stunted. Check out our tips:

Masses of tiny blue, white, pink, or purple flowers appear in late winter and early spring, covering its stems in blossoms for a striking early-season display. This mass flowering also makes it an important early food source for pollinators and cold weather hummingbirds.

Rosemarinus is Latin for “dew of the sea,” and officinalis indicates this is an official variety used in medicine, or that the plant is considered to have medicinal properties.

Slow-growing in its first year or two, it will grow up to 4 feet tall with a spread of 6-8 feet, depending on the variety you’ve chosen.

Grown for culinary, cosmetic, and ornamental value, rosemary is easy to grow and care for when given the right conditions.

In the Kitchen

This classic herb has long been used with meats such as lamb, pork, veal, and stews, and it’s a natural with poultry and fish.

Along with other herbs – like marjoram, oregano, savory, and thyme – rosemary is an ingredient in one of the essential blends of French cooking, herbes de Provence.

With its delicious and distinctive pinewood flavors, it’s also liberally used with veggies and in dressings, vinaigrettes, butters, jam, breads, and stuffing.

The leaves, or needles, give their best flavor when used fresh, but they also store well by either freezing or drying.

And a chunk of dried wood from pruning, or green stems placed on the barbecue grate, add a sweet, smoky taste to many grilled foods.

Pour Les Toilettes

With intense fragrance, the essential oils are popular for use in perfumes, lotions, and toiletries, while the dried needles and flowers are a favored addition for linen sachets, potpourris, and aromatherapy.

The oil is often used as a stimulant said to boost memory, concentration, and mental clarity. It’s also often found in dental health products, such as mouthwash, due to its astringent, antibacterial properties.

You can also enjoy its aromatics in your own bathtub.

Bundle 4 to 6 tender tips together. Then, tie them in a piece of cheesecloth to make a sachet. Add to your bathwater, and once it’s been warmed, gently squeeze the sachet to release the oils, and breathe deeply. Repeat until dreamy…

For the Ornamental Garden

With its fragrance, profusion of tiny flowers, shape, and robust growth, the many cultivars of Rosemarinus are also useful and handsome ornamentals in the garden.

A ground-hugging cultivar such as R. officinalis prostrates ‘Clera McHenry’ can effectively be used as a ground cover. Tall, upright varieties such as R. officinalis ‘Tuscan Blue’ make a handsome hedge, or can be used as anchor plants. And dwarf varieties like ‘Roman Beauty’ can easily be trained and trimmed into bonsai shapes, or standardized.

There are two main varieties, upright and creeping, both of which are highly fragrant. Uprights are better suited for shaping and as specimen plants, while the creepers are good for ground covers, or to add slope stability.

This garden stalwart also makes an excellent companion plant, as few pests find its intense flavor and fragrance to be palatable.

It may become susceptible to powdery mildew when crowded or grown in a wet environment. Ensure your plant has plenty of sunshine, good drainage, and adequate air circulation to restore health.

When needed, prune hard after flowering by cutting back by one-third to one-half. And savor the intense aromatics as you remove the cut branches – it’s like being at the spa!

Also, you’ll want to save the larger pieces of wood after a hard pruning.

Stripped of their leaves and branches, a chunk of rosemary smoking on the barbecue adds delicious, savory flavor to grilled foods!

Cultivation and Care

Rosemary is easily grown from seed and stem cuttings, which you can learn about here, and loves an environment similar to its native habitat.

Give it a full-sun exposure in a well-drained location, with average soil. It requires only moderate amounts of water, and a top dressing of organic material in the spring will round out its care requirements.

It can’t abide wet feet and enjoys soil that has a bit of texture from sand or small rocks to improve drainage.

Collect seeds from the stems in summer after they’ve dried, and sow in early spring. Or, after flowering, take stem cuttings from old wood with a bit of new growth at the tip.

For aromatherapy and perfume, the essential oils are most concentrated just before the plant flowers, but needles can be harvested at any time of the year.

For a Fresh, Potted Supply

Rosemary does grow in pots, but it won’t thrive in containers the way it does when grown in the ground.

With minimal care, this bushy herb will grow with abandon, often growing 12 to 16 inches in a summer. But if grown in pots for too long, plants can lose their vigor and become stunted.

To ensure the most tender, flavorful leaves for the kitchen herb garden, replace your container every spring with a fresh plant.

It’s easy to start new plants from cuttings.

For a steady supply of young potted plants, take several stem cuttings each spring and plant them up in two 6- to 8-inch pots. Leave them in a sheltered spot in the garden with morning sun and adequate moisture until the next spring, when the pot with the best growth may be moved to the kitchen garden.

The second pot can come indoors in autumn to overwinter if needed. Find a bright spot to grow indoors, water regularly, and mist the needles weekly to help to provide humidity.

To keep rosemary compact, pruning should be done after flowering in late spring to mid-summer. And avoid pruning in autumn or winter, as this tender perennial needs to harden off to survive cold weather.

Thanks for your question, Antoinette. Chives should do well in your hardiness zone, given the proper conditions. Are they planted in well-draining soil, in an area with full sun? What specific issues are you experiencing with your plants? With a little more detail, we can try to help you to troubleshoot! In the meantime, please see our article on growing chives for more info.
