Stowell’s Evergreen Sweet Corn is one of the oldest corn varieties in existence, dating back to the mid 1800s. This heirloom, open-pollinated sweet corn varieties produces consistent 8″ ears of delicious white kernels. Because it is a standard (su) variety, it matures slightly later than (se) or supersweet varieties. Stowell’s Evergreen Sweet Corn is relatively drought-tolerant and adaptable to a wide range of growing conditions. Ears of this variety remain in the milking stage for longer than most, hence the name “evergreen”. Old timers were known to hang the stalks in the barn and harvest ears as they were needed. This is a great variety for canning or freezing.
Sweet corn should be planted in the spring after the last frost date. Sweet corn can be grown throughout the warmer months up until fall, as long as time is permitted for harvest before first frost. Succession planting is recommended with at least two plantings, one in early spring and one in late summer/early fall. Corn ear worm pressure will be greater in the warmer months, but this can be alleviated by applying spinosad to silks and tassels once they appear.
We recommend planting sweet corn using a walk-behind planter like our Hoss Garden Seeder. Once plants emerge, thin plants to 6-8″ depending on adequate irrigation. If drip irrigation is used, in-row spacing may be as close as 6″. If water is scarce, a wider in-row spacing will be necessary. For pollination purposes, corn should be planted in a square plot with rows on 30-36″ spacing. Planting a few long rows will result in poor germination and absence of kernels on the cobs.
