Glass Gem Corn is a visually stunning variety of maize, known for its kernels that shimmer with translucent, rainbow colors. This heirloom flint corn, developed through selective breeding from traditional Native American varieties, has become a symbol of seed preservation and natural beauty. Its vibrant appearance makes it highly sought after for both cultivation and decoration. This guide will direct you to reliable sources to purchase either the seeds or the dried kernels, depending on whether you intend to grow it or use the finished product.
Understanding Glass Gem Corn
Glass Gem Corn is classified as a flint corn, a type of Zea mays known for its hard, outer-shell kernels that resemble the mineral flint, hence the name. Unlike sweet corn, which is eaten fresh off the cob, this variety is typically left on the stalk until the kernels are fully dried and cured. The dried kernels retain their spectacular colors, making each ear a unique piece of natural artwork.
While prized primarily for its ornamental qualities, Glass Gem is also fully edible. The hard kernels can be popped to create popcorn, although the vibrant colors will be lost in the popping process. The kernels can also be ground into cornmeal, which can then be used to make polenta, grits, or various baked goods. This combination of decorative beauty and functional use makes the heirloom variety popular.
Purchasing Seeds for Cultivation
For those looking to experience the magic of harvesting their own multicolored ears, purchasing high-quality seeds is the first step. The most reliable sources are specialized heirloom seed banks and non-profit organizations dedicated to seed conservation. Organizations like Native Seeds/SEARCH, which originally preserved the variety, often sell Glass Gem seeds and can guarantee true-to-type heritage stock.
Reputable commercial seed retailers also offer Glass Gem seeds, often listed as an open-pollinated variety. When sourcing from these companies, check for details like the days to maturity, which is typically around 100 to 120 days, to ensure it suits your growing season. It is advisable to buy from a supplier who details their seed testing, ensuring a high germination rate.
Successful cultivation requires planting seeds in a block of at least three rows rather than a single line to ensure full kernel development. Seeds are typically planted after the last expected frost date. Seasonal availability means that many suppliers will temporarily sell out of this popular variety during peak spring planting time, so securing your seeds early is recommended.
Purchasing Dried Kernels
If your goal is to use the finished product for decoration or immediate consumption, you will be looking for the dried ears or shelled kernels. Dried ears of Glass Gem Corn are commonly available in the autumn months, which aligns with the typical harvest and curing period. These decorative cobs can be found at seasonal venues such as local farmers’ markets and pumpkin patches, where independent growers sell their unique produce.
For year-round access, large online marketplaces and specialty craft supply stores frequently stock the dried cobs, particularly those intended for ornamental displays. When purchasing decorative ears, look for product descriptions that emphasize the color vibrancy and the intact, translucent sheen of the kernels. Quality dried kernels, which can be popped or ground into flour, are also sold by some specialty food producers and online vendors.
If you are buying shelled kernels for popping, ensure the moisture content is specifically mentioned as suitable, ideally between 13% and 14.5%. Kernels that are too dry or too moist will not pop correctly. Buying the finished product offers a straightforward transaction without the commitment of a four-month growing cycle.
