Spinacia oleracea The Northwest's favorable conditions for spinach production allow us to focus our selection criteria on flavor, vigor, and bolt and disease resistance. The highest-protein vegetable, leafy spinach greens boast an unmatched, synergistic complement of vitamins, minerals, flavonoids and carotenoids that when combined, protect eyesight, help prevent the buildup of cholesterol, and target cancer-causing free radicals.

Days to maturity are calculated from date of direct seeding.

• Optimum soil pH range is 6.5-7.5
• Spinach grows best during cooler weather of early spring and fall
• Soil temperature above 80°F can cause erratic germination
• Bolting is caused by rising temperatures, day length and water stress; see specific varieties for bolt resistance
• Apply 1/2 cup of TSC's Complete fertilizer per 5 row feet, and 1 inch of compost

Best spinach I have ever grown

I was a market organic veg grower for 15 years. Now at home gardening and tested this spinach a few years ago. Nothing like it! I just started the main harvest of large flat leaves just 34 days after sowing on July 7. VERY slow to bolt, even as bolting the leaves taste wonderful. Easy to wash. Side-by side growing test with Bloomsdale show that this one is the only one I will grow, from now on.
Blah Flavor

I didn't think this variety had a very good flavor. Kind of bland and not very spinach-y. Was slower to bolt than the Bloomfield Longstanding that I had also planted, which was good, but due to the blah taste, I'm going to find a different variety.
