Rosemary Seeds for Planting: A Fragrant Perennial Herb from Seed

Rosemary is a woody, evergreen herb with needle-like leaves that smell wonderful in the garden and even better in the kitchen. Starting it from seed gives you lots of plants for the price of a single nursery transplant, and you get to grow them in your own conditions from day one. Our collection of rosemary seeds is a great way to add a classic herb to your garden. Fresh sprigs bring savory flavor to roasted potatoes, bread, chicken, and marinades, and the plants make an attractive, drought-tolerant addition to herb beds and containers.

Rosemary Seeds for Sale: A Long-Lived Herb for Garden and Kitchen

When you browse rosemary seeds for sale, you're choosing a plant that can last for years. Rosemary grows into a bushy shrub that stays green through the seasons, with pale blue flowers that bees love in spring. Once it's established, it needs little more than sun, good drainage, and an occasional trim. In the kitchen, the leaves are used fresh or dried, and the woody stems can even double as skewers for the grill. Because rosemary is so productive, a few plants are usually enough for a household.

Rosemary from Seed: Start Early and Be Patient

Growing rosemary from seed takes a little more patience than most herbs, but the process is simple. Start seeds indoors about eight to twelve weeks before your last spring frost. Rosemary seeds need light to sprout, so press them onto the surface of moist seed-starting mix and cover them with only a very thin layer of soil. Keep the tray in a warm, bright spot, and water gently from below to avoid washing the seeds away. Once seedlings have several sets of leaves and the weather has settled, harden them off and transplant them into a sunny spot with fast-draining soil, spaced two to three feet apart. The Seedtime planting calendar works out your indoor sowing date from your frost dates, and the layout planner helps you give each plant room to grow into a shrub.

Frequently Asked Questions

How long do rosemary seeds take to sprout?

+

Expect anywhere from two to four weeks, sometimes longer, and expect uneven results. Rosemary has a low germination rate, so sow more seeds than the number of plants you want. Warm soil, around 70°F, helps, and a heat mat under the tray speeds things up. Keep the mix lightly moist but never soggy, and don't give up if nothing happens in the first couple of weeks.

Will rosemary survive the winter?

+

It depends on your climate. Rosemary is a tender perennial that handles mild winters outdoors in warmer regions, but it can be damaged or killed by hard freezes. In colder areas, grow it in a pot and bring it indoors before frost, then set it in your sunniest window or under a grow light. Water sparingly over winter, because indoor plants are especially prone to rot.

When can I start harvesting rosemary, and how should I prune it?

+

Let young plants get established for the first season, then harvest freely. Snip the top few inches of stems rather than stripping leaves, and never cut back into bare, woody growth, which often won't regrow. Regular light trimming keeps the plant bushy and productive. Prune after flowering to shape the shrub.

Why is my rosemary turning brown or dying?

+

Overwatering is the most common cause. Rosemary comes from dry, rocky ground and rots quickly in soggy soil, which causes browning from the base and dropping needles. Plant it in gritty, fast-draining soil, let the top inch or two dry out between waterings, and make sure pots have drainage holes. Poor air circulation indoors can also cause mildew, so give plants a little space.

Is rosemary grown from seed the same as rosemary from cuttings?

+

Not exactly. Plants grown from seed vary, so one may be more upright, spreading, or aromatic than another, while cuttings are exact clones of the parent. Seed is a great way to grow a lot of plants cheaply, and you can keep the ones you like best. If you find a favorite, you can take cuttings from it and grow identical copies.
