I just started saving seeds... If you are growing a radish,then do not pick a few. When the stalk(leafy part) is about 2-3 feet tall you will see the seeds at the top of the stalk(it kind of looks like mini broccoli) Then let the seeds dry out,and plant them :)
Anything with seeds should be considered a fruit.

Begonias do have seeds. Most people do not have the space or ability to grow them from seed. It is far less trouble to buy them in flats and put them into your garden.
The three most popular varieties of begonias for gardening are tuberous begonias, Rex begonias, and fibrous rooted begonias. Fibrous rooted begonias are also called the old fashioned wax.
Scarlet Begonias was created in 1974.
