530 seeds. 45 Days. Spinacia oleracea. Annual.
 
Spinach 'Bloomsdale Long Standing' has dark green, savoyed leaves. This 1826 American heirloom was developed to be slow to bolt. It is also known as Burlington and Late Seeded Bloomsdale.
 
In the spring of 2023, I grew three spinach varieties: Viroflay, Giant Noble and Bloomsdale Long Standing. The Bloomsdale Long Standing spinach was smaller than the other two spinach varieties in our experiment, but its puckered leaves make salads more light and airy. In our experiment, Bloomsdale Long Standing bolted after Viroflay.
 
Sowing Spinach Seeds: 
 
Sow seeds outdoors 1/4 inch deep and 2 inches appart in early spring as soon as the soil thaws. Or sow spinach seeds in late summer. Thin the seedlings to 4–6 inches apart. Space rows 16 inches apart.  Spinach seeds are dormate in temperatures above 80 degrees fahrenheit. Full sun to part shade.
