|'Oklahoma Delaware White', also known as 'Puhwem', is an heirloom variety. The stalks are quite tall, sometimes reaching up to 15 feet. Each produces two ears with pink silks, about 5 feet up. The stalks are extremely sturdy, and useful for stringing some pole beans. Not generaly recommended for areas north of Zone 6. This variety is generally used for making flour. Originally domesticated by Mesoamericans, it is a staple food with many other traditional uses. Home gardeners love to grow corn, and there are many varieties suited to different climates. Plant seeds 1 inch deep in rows or clumps, two weeks after the last frost date. Corn needs rich soil, full sun and adequate moisture to produce good ears. It is wind pollinated, so if you want to save seed, you will need to either stagger the planting time of different varieties, or plant them 1/4 mile apart. Water deeply.
