Cornsilk is edible and is considered to have many medicinal properties. See related link below.
No. The moths (adults) will lay their eggs on any fresh silks, regardless of the corn type.
Yes, they do. The structure of the corn plant which has the cob, silks, and kernels contained inside the husk is commonly referred to as an ear of corn.
Corn (maize) "goes to seed" once the tassels have released their pollen onto the silks down where the ear develops.
Corn is ready to be picked when the kernels are plump and milky, and the husks are dried and brown. This usually occurs about 20 days after the silks appear on the corn.
The tassels on top of the corn plant are the stamen that produce pollen. The silks ar the ends of each corn cob are the pistils leading to the ovaries. Each one will produce a grain of corn.
The "silks" are the female flowers. The "stalk" at the top is the male flower. Pollen from the stalk is windblown around and some of it inevitably sticks to the silks. For every silk that is pollinated, that ear of corn will have one kernel develop - hence the majority of silks must catch a grain of pollen to have well-filled ears. Ears "missing" kernels (usually near the tip) had a few silks that did not get pollen grains. Since corn is wind pollinated, it should alwyas be planted in blocks (like 4x4, 8x8) to help assure pollination.
You can determine when corn is ready to pick by gently squeezing the kernels to see if they are plump and milky. Additionally, the husks should be green and the silks should be brown and dry.
non is eatable
Corn is monoecious (mon-ee-shuss) which means that there are both male and female flowers on each corn plant. In some monoecious plants, male and female parts are in the same flower. In corn, male and female flowers are in different locations - the male flowers form a tassel which is at the top of the plant. The female flower is located at the junction of leaves and stem. It consists of a collection of hairs (silks) enclosed in the husks of what will become the ears. These silks are pollen-receiving tubes. Wind-blown pollen from the male flowers (tassel) falls on the silks below. Each silk leads to a kernel, and pollen must land on all silks for the ear to fill out completely with kernels. Kernel "skips" (ears only partly filled out with kernels) often are the result of poor pollination.
No it's not eatable
The colours a jockey wears are known as 'silks'.
If you really want to. Yes, they are eatable.
