Coverage & Planting Details
| Coverage | This packet sows up to 37 feet. |
|---|---|
| Row Spacing | 18" |
| Seed Depth | ⅛" |
| Seed Spacing | A group of 3 seeds every 6" |
| Thinning | When 1" tall, thin to 1 every 6" |
| Germination | 10–14 days |
| Start Indoors | 8 to 10 weeks before your average last frost date; transplant outside 4 to 6 weeks after starting inside. |
| Direct Sow | 4 to 6 weeks before your average last frost date, as soon as soil can be worked, or 8 to 10 weeks before your average first frost date. Mild Climates: Sow in fall and winter for cool–season harvest. Ideal soil temperature for germination is 60°–70°F; soil temperature over 78°F halts germination. |
| Growing & Harvesting | Harvest in the morning and before temperatures get above 90°F. You might want to discard the outer leaves, as they tend to be more bitter than inner leaves. Dunk plants in cold or ice water to cool, then drain before storing. The leaves can actually be harvested any time in a ôcut-and-come-againö fashion; this is particularly good when seeds are sown too late in the spring, and warm weather is approaching quickly, threatening to cause plants to bolt. In fall, harvest after first couple of light frosts; flavor is actually improved with light frost. When plants are 6" across, entire head can be cut at the base. |

- SaraVerified ReviewerRated 3 out of 5 stars4/27/26Delicious, but pretty sure I got lettuce seeds
I sowed these seeds into a 6-cell and planted them out in early March (zone 8b). It is late April now and they are going into maturity -- while beautiful and healthy, they look and taste just like butterhead lettuce. I'm not entirely disappointed because they taste so good, but I was really looking forward to getting those frilly chicory leaves. I'm very confident that I didn't mix up the seeds on my end, because I don't even have lettuce seed packets. I'm wondering if anyone else is experiencing the same thing? I purchased the seeds at the end of 2025 (the packet says packaged for 2026).

Besides just making a beautiful presentation, it was never bitter early season, mid season, or late in the season. My husband had never had Endive before and I was afraid he would turn his nose up at it. But he did not, it turned out he really enjoyed it so that's the best testimonial I can give to you.
