Is flower nectar sweet?
Nectar is a sweet liquid secreted by plants, and especially by flowers. Nectars range in sweetness from as little as 8% to as high as 50%. Nectar is produced in the plant by glands called nectaries. Floral nectaries can be located on various parts of the flower, depending on the species.
Do flowers make more nectar?
You need a flower to make nectar, and those plants that do produce nectar will produce it as long as their flowers are open. Some plants are hermaphroditic, meaning they’re both male and female. These plants tend to produce nectar every day. When the nectar is depleted, the plant will make more, but it takes some time.

The female elements are collectively called the pistil. The top of the pistil is called the stigma, which is a sticky surface receptive to pollen. The bottom of the pistil contains the ovary and the narrowed region in between is called the style.
What does the style do in a flower?
Style – This is the name for the stalk of the pistil. When pollen reaches the stigma, it begins to grow a tube through the style called a pollen tube, which will eventually reach the ovary. The style therefore acts as a buffer against pollen contamination, since only compatible pollen is able to grow a pollen tube.

Stigma is the swollen structure at the end of a style. Stigma along with the style and ovary compromises of the pistil which is known as the female reproductive system of the flower.
