Planting & Growing
Glass Gem Ornamental Corn will grow to be about 5 feet tall at maturity, with a spread of 18 inches. When planted in rows, individual plants should be spaced approximately 18 inches apart. This fast-growing vegetable plant is an annual, which means that it will grow for one season in your garden and then die after producing a crop.
This plant does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. This plant is a heavy feeder that requires frequent fertilizing throughout the growing season to perform at its best. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This is a selection of a native North American species.
Glass Gem Ornamental Corn is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its height, it is often used as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
