How to Collect Petunia Seeds

Updated April 17, 2017

Petunias are capable of producing an abundance of blooms throughout the growing season. The blooms of the petunia plant are available in single blooms, double blooms, solid, striped, veined, ruffled, or smooth. They make excellent additions to rock beds, ground covers and window boxes. Petunias are also available in tendencies that mound, wave, cascade and climb. To capture the treasures of the petunia bloom before the seeds have a chance to disappear, follow the instructions below.

Open the end of the tulle bag with your fingers.

Place the open end of the tulle bag over the spent bloom, careful not to knock the bloom off of the petunia plant.

Pull the drawstring on the tulle bag and tie loosely to the stem of the petunia plant.

Observe the tulle bag daily for seeds to appear once the seed pod splits.

Use scissors to cut the stem of the plant about 1 inch past the tulle bag so that a portion of stem is sticking out of the bag.

Open the drawstring of the tulle bag carefully over a pie plate.

Remove the stem from the tulle bag.

Write the date and label on a piece of paper, fold and stick into the bag with the petunia seeds.


Petunia seeds are very small and are released once the seed pod begins to split. Since timing is crucial, it is recommended to put the tulle bag on the bloom as soon as the bloom has expired.
