Overview

The vibrancy and beauty of petunias stand out as a staple of summer. Sure to brighten any garden, petunias can be grown in the ground, containers or hanging baskets. The nice thing about petunias is that you can allow the flowers to dry and collect the seeds to grow in years to come. There are different ways to store petunia seeds for best viability, however, so storage of these beauties should be more than labeling a few envelopes and filling them with seeds.

Step 1

Look over your seeds to make sure they are fully dry. If not, spread them out on a paper towel and leave in a room with low humidity for a few days.

Step 2

Label a plastic bag with the type of seeds, the color of the blooms and the date you collected the seeds.

Step 3

Place your dried seeds into the plastic bag, press out any excess air and seal the bag well. If you have them available, you can place a silica gel packet inside the bag.

Step 4

Store the bag in a dark, cool, dry place, such as a closet or seed box for anywhere from 3 to 4 years.

Step 5

Increase your storage time and viability to 5 years by placing the plastic bag of seeds into a refrigerator.
