Why We Love It
Dark, glossy leaves that love the cold, so fresh greens grow right through winter.

Smoothie season doesn't end just because the garden is asleep. This spinach is built for the cold: the variety does best in winter and likes temperatures between 40 and 70F. Let it get too warm and it tends to bolt. The organic heirloom seeds sprout in 5 to 10 days and reach maturity in about 45. Harvest the older outer leaves first so the young ones keep coming. Those dark, glossy, crumpled leaves work in salads, in cooking, and yes, in the blender.
Cold outside, fresh greens inside. Winter just lost a little of its edge.

Description
Grow your own nutritious greens with our Organic Spinach Seeds! These seeds will sprout into delicious spinach, perfect for adding to salads, smoothies, and more. These seeds are organic, non-GMO, and heirloom so you can grow the highest quality harvest.
Instructions:
We recommend using the following to sow the seeds:
- 12 Cavity Greenhouse or Planter with Humidity Dome
- Soil Pods
- Liquid Fertilizer
Spinach prefers cooler climates, and this particular variety does best in winter. In fact, if it’s too warm, they’re likely to “bolt”. Spinach is a fast-growing plant, and as such would benefit from some fertilizing.
The best method for doing so is to harvest the outer, older leaves so that the younger leaves have time to grow in. This variety works great in salads or in cooking.
