Recommended Spinach Varieties
While there are many things that are called spinach, including some oddball things like chard, the spinach plant is known by the botanical name Spinacea oleracia. Believed to have originated in ancient Persia, it rapidly spread from there to India, then China, and then throughout most of the world.
Three basic types of spinach are currently being sold today. These are savoy or crinkled-leaf spinach, flat leaf spinach, and semi-savoy hybrid varieties.
Savoy Varieties
When you go to the supermarket, it’s likely that savoy spinach is what you’re going to see in the produce aisle. Savoy types tend to have a crinkled or curled leaf shape, and work beautifully for fresh eating.
| Variety | Growing Time | Description | Where To Buy |
| Bloomsdale | 50 days | Heirloom savoy variety from 1925, extremely popular. Cold tolerant. | Buy Seeds |
| Escalade | 43 days | Mild flavor, upright habit, mildew resistance, and a reluctance to bolt. | Buy Seeds |
| America | 43 days | Thick green leaves perfect for freezing, canning, or fresh use. | Buy Seeds |
| Palco | 38 days | Quick-growing savoy type. Bolt and disease-resistant. | Buy Seeds |
Flat-Leaf Varieties
While these spinach varieties look much different from the savoy due to their smooth, uncurled leaves, they are still spinach! Easier to clean than savoy varieties, the flat leaf spinach types are often used for processing into frozen or canned spinach. They also work well in other cooked applications where the leaf shape isn’t as identifiable.
| Variety | Growing Time | Description | Where To Buy |
| Red Kitten | 40 days | Medium green leaves with red stems. High resistance to downy mildew. | Buy Seeds |
| Akarenso | 50 days | Slightly serrated Japanese spinach variety with red-purple stems. Mild flavor. | Buy Seeds |
| Baby’s Leaf | 40 days | Lots of leaf, very little stem. Early producer. Easy to clean. | Buy Seeds |
| Renegade | 42 days | Succulent, round dark green leaves. Hybrid variety with consistent growth. | Buy Seeds |
| Giant Nobel | 48 days | Heirloom from the 1920’s. Extremely large plant, spreading habit. Slow bolt. | Buy Seeds |
Semi-Savoy Varieties
Hybrids of the flat-leaf and savoy spinach types have produced a semi-savoy. It has some of the easier-to-clean benefits of flat leaf varieties, but works well in both fresh and cooked uses.
| Variety | Growing Time | Description | Where To Buy |
| Kolibri | 29 days | High downy mildew resistance, quick growing. Great for baby leaf production. | Buy Seeds |
| Seaside | 40 days | Resistant to heat bolting, semi-smooth leaves. Downy mildew resistant. | Buy Seeds |
| Responder | 42 days | Strong germination. Disease-resistant with uniform growth, great flavor. | Buy Seeds |
| Carmel | 25 days | Quick-growing, very uniform spinach with high downy mildew resistance. | Buy Seeds |
| Okame | 50 days | Slow to bolt and can take hotter temperatures. Downy mildew-resistant. | Buy Seeds |
| Crocodile | 45 days | Extremely heat resistant. Great as both baby leaf and mature. | Buy Seeds |
Other “Spinach” Types
These other plants are often confused with Spinacea oleracia and referred to as spinach. While they may be similar in how they’re used culinarily, they aren’t the same plant. However, they can be quite popular. Seeds for these plants are often found alongside spinach seeds in catalogs or online.
Chard, also known as Swiss chard, is often called “beet spinach” or “perpetual spinach”. While unrelated, it is often grown for its leafy greens as well, although the stalks can also be consumed.
Strawberry spinach is a common name for Blitum capitatum, also known as Chenopodium capitatum or strawberry blite. This plant produces edible leaves, but is often grown for its bright red edible fruit.
Red Aztec spinach (Chenopodium berlandieri) is widespread as a weed plant. More commonly known as red lamb’s quarter or goosefoot, this particular plant produces edible leaves. It’s not a true spinach, but it has a similar flavor when cooked.
