This white sweet corn is an heirloom that stores for weeks into winter, as discussed in my book, Forgotten Skills of Self Sufficiency. We hang the entire plants upside down in a shed or garage and then harvest the sweet corn as desired through Christmas. 50 heirloom, chemical-free seeds per pack. HOW TO GROW: Plant seeds 1 inch deep after all danger of frost has passed. For best pollination, plant corn in a block of at least ten plants by ten plants (larger if possible). Harvest when the corn is tender and the silk has just dried. Annual. 100% natural, grown without chemicals. Free shipping on orders over $34.
