Corn (Mays)

The Corn (Mays) is generally described as an annual graminoid. This is not native to the U.S. (United States) and has its most active growth period in the summer . The greatest bloom is usually observed in the early summer, with fruit and seed production starting in the summer and continuing until summer. Leaves are not retained year to year. The Corn (Mays) has a short life span relative to most other plant species and a rapid growth rate. At maturity, the typical Corn (Mays) will reach up to 8 feet high, with a maximum height at 20 years of 0 inches.

The Corn (Mays) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by seed. It has a slow ability to spread through seed production and the seedlings have high vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 32°F. has low tolerance to drought and restricted water conditions.
