How to Get Seeds From Broccoli


A member of the cabbage family, broccoli is grown by many home gardeners. Broccoli seeds are usually started indoors, the small seedling plants transplanted to the garden in the early spring and a fall crop planted in the late summer. Seeds from broccoli plants are harvested after the flowers appear and produce seed heads on the plants. In order to save seeds from broccoli, the gardener should allow several plants to flower and create seed heads.

Step 1

Select one or more of the strongest looking broccoli plants in your garden from which to save seed.

Step 2

Allow the plants to mature past the edible stage of growth.

Step 3

Allow the plants to flower. The flowers will be small, with yellow petals.

Step 4

Remove the silique, or seed pod, when they form on the stalks. Place the silique on newspaper, turning several times a day, to dry thoroughly.

Step 5

Break apart the seed pods and collect the seeds inside. Work over a clean sheet of newspaper so the seeds will not scatter.

Step 6

Place the collected, red-brown to black, seeds in an envelope. Seal the envelope and label with the contents and date.
