Corvair Spinach

Corvair is a smooth flat spinach, ready in about 27 days. Sweet, tender leaves for salads raw or wilted in a pan. Spinach is fast and cool-season — it bolts in heat and long days, so grow it in early spring and fall.
“A tender, fast cool-season green for salads and cooking.”

Zone 6bGreenhouse or cover on: your start slides ~4 weeks earlier and your harvest stretches ~3 weeks later (shown striped).
Planting seeds straight in the ground only works where the season's long and warm — most gardeners start seeds indoors or buy young plants, or you'd pick your first tomato right as frost hits.
Comfortable — first ripe fruit lands around late Apr, well before your typical frost (~late Oct).

Growing Corvair — the things that trip people up
- Spinach bolts (shoots to seed) fast in heat and long summer days. Grow it in the cool and short days of early spring and fall, and sow a little every couple of weeks for a steady supply.
- Pick the outer leaves young, or cut the whole plant. Give it rich soil and steady water — stressed spinach bolts even sooner.
