Spinach Seeds for Planting: Crinkled, Smooth, Red-Stemmed, and Winter Varieties

Spinach is one of the first crops that goes in the garden in spring and one of the last that comes out in fall. It grows quickly in cool weather, takes very little space, and gives you crisp, tender leaves for salads, smoothies, sautés, and soups. Our collection of spinach seeds covers classic crinkled Bloomsdale types, smooth-leaf varieties, hybrids bred for vigor, a red-stemmed beauty, and winter-hardy types for fall sowing. Growing spinach from seed is inexpensive, and a single packet can supply several small sowings through the cool seasons.

Spinach Seeds for Sale: Bloomsdale, Viroflay, Space, Giant Winter, and More

When you browse spinach seeds for sale, the leaf type is the first thing to choose. Bloomsdale, Bloomsdale Longstanding, Long Standing Bloomsdale, Abundant Bloomsdale, and Winter Bloomsdale all have the dark green, crinkled (savoyed) leaves that gardeners love for their rich flavor, and the long-standing types are known for holding up longer before they send up flower stalks. Viroflay and Giant Noble have large, smooth leaves that are easy to wash and perfect for cooking, and Butterflay and American are other dependable green spinaches.

If you want vigorous, uniform plants, look at the F1 hybrids Space, Regiment, and Renegade. For something different, Beaujolais has deep red stems that add color to a salad bowl. Giant Winter and Winter Giant are good for fall sowings that carry through into the cold months, and many varieties here are heirloom and open-pollinated, so you can save your own seed.

Growing Spinach from Seed: Sow Early in Spring and Again in Fall

Spinach loves cool soil and cool days, so plant it as early as the ground can be worked in spring, a few weeks before your last frost. Sow seeds about a half inch deep and an inch or two apart in rows, then thin seedlings to three to four inches. Expect sprouts in one to two weeks, and plan to harvest in roughly six to eight weeks. For a fall crop, sow seeds about six to eight weeks before your first expected frost, when the soil begins to cool. Spinach grows best in rich, well-drained soil that stays evenly moist, with full sun in cool weather. The Seedtime planting calendar works out your spring and fall sowing windows from your frost dates, and the layout planner helps you fit a fast crop of spinach into a bed before warm-season plants take over.

Buy Spinach Seeds with One Flat Shipping Rate

When you buy spinach seeds here, you can combine packets from different suppliers in one order and pay one flat shipping rate rather than a separate shipping charge for each supplier. Seedtime members also get discounts on seed packets, so if you're planning a full cool-season garden, compare Seedtime's plans to see what membership includes.

Frequently Asked Questions

Why did my spinach bolt, and how can I prevent it?

+

Bolting means the plant sends up a flower stalk, which turns the leaves bitter and ends the harvest. Spinach bolts when days get long and warm, so most plants go to seed by early summer. Sow as early as you can, choose slow-bolting types like the long-standing Bloomsdale varieties, keep the soil evenly moist, and use shade cloth during warm spells. Pull plants that bolt and replace them with a summer crop.

How do I harvest spinach so it keeps producing?

+

Pick the outer leaves first when they're about three to four inches long, and leave the center growing point intact so new leaves keep forming. You can also cut the whole plant an inch above the soil, and it will often regrow for a second, smaller harvest. Harvest in the morning when leaves are crisp, and rinse well, since savoyed leaves hold grit.

Can I grow spinach through the winter?

+

In many climates, yes. Sow a winter-hardy variety in fall so that plants reach a small size before the coldest weather. Mulch lightly, and protect plants with row cover or a cold frame if temperatures drop well below freezing. Growth slows to a crawl in the darkest months, then picks up quickly in late winter, giving you some of the earliest leaves of the year.

Why won't my spinach seeds sprout?

+

Heat is the usual culprit. Spinach germinates best in cool soil, and seeds often stay dormant or rot when soil temperatures climb above the 70s. If you're sowing in late summer for a fall crop, keep the bed cool and shaded, water the soil before sowing, and cover the row with a board for a few days to hold in moisture. Old seed and crusted soil can also hold sprouts back.

Can I grow spinach in containers or partial shade?

+

Yes to both. Spinach does well in a pot at least six to eight inches deep, and a window box works for baby leaves. In partial shade, plants grow more slowly but stay tender, and they bolt later than those in full sun. Shade is especially helpful in late spring, when afternoon sun can push plants to flower early.
