Flower Parts and Functions

1 Petals
The most attractive part of most flowers. Colour often attracts insects to aid pollination. A whorl of petals is called a Corolla

2 Sepal
In buds the sepals enclose and protect other parts of the flower. As the flower opens the green sepals curl away or fall. Several sepals together form the Calyx

Petals and sepals together form the Perianth. In tulips and some other flowers the petals and sepals are not separate and they are called Tepals.

3 Anther
The anther carries the male pollen. Anthers are supported by 4 the Filament that together with anthers make up the Stamen.

5 Stigma receives the pollen and is generally at the top of the 6 Style. The style connects to the 7 ovary and these parts collectively are called the Pistil or female organs. The ovary is where the seeds develop.

8 Receptacle is the fatter part that supports the flower above the stalk.

9 Pedicel is the stalk or stem of an individual flower. With a group of flowers on one stem or inflorescence this is named a Peduncle.

Just a bit of botany can go a long way for gardeners but it is good to know the basics.
