Giant Winter Spinach

Giant Winter Spinach


45 days. A special strain bred specifically for late summer and fall seeding for a crop in early spring. The large dark green leaves are smooth, semi savoyed and flavorful. Wonderful steamed, or excellent in fresh spinach salads. Remarkably cold hardy, and stands well in all but the worst weather we experience here in the Northwest.

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

Direct Sowing
• For baby spinach sow 20-25 seeds per foot in a 2 inch wide furrow, in rows 6 inches apart, thin to 1 inch
• Sow July—August for a fall crop
• Sow late-August for an overwintering crop

Great Winter Variety

Grew this over winter under greenhouse panels laid over my garden boxes here in Reno, NV. I planted it in September and was harvesting the sweetest most tender melt in your mouth spinach starting after Christmas and ending in March. The flat leaves made it so easy to rinse. Each plant was so prolific in the cool season that I had plenty to share with a local food pantry. This will be a staple in my winter garden from now on.
