How to Collect Hollyhock Seeds


Hollyhocks feature tall, majestic flowering stalks that can grow up to 9 feet tall. Landscapers often select hollyhocks as a backdrop to a flower garden or along fences. If you have hollyhocks and would like to plant more in other areas of your yard or pass some seeds on to a friend, collect the seeds at the end of the growing season.

Step 1

Wait for the seed pods on the hollyhock to turn brown. The hollyhock seed pods develop at the base of the flower. While they start out green, they turn brown and papery as the seeds start to mature.

Step 2

Snip the seed pods off the plant when they become dry and papery using a pair of pruning scissors. Drop the pods into a wicker basket. Leave at least one seed pod on the hollyhock plant so it can naturally reseed itself.

Step 3

Lay the seed pods out on a screen to dry for three more days. Place the window screen on a counter and place a 2-inch block underneath each corner. A child's alphabet block would work fine. Leave the seed pods alone and allow them to dry the full 72 hours.

Step 4

Peel back a layer of the seed pod. Inside you will see a ring of seeds. At this point the seeds should be dark brown to black in color. If they are, peel the pod and empty the seeds into a sieve. If they are not, close the pod back up and allow it to continue to dry. Check the seeds daily to see if they have turned color. Once they have, open the pod and empty them into a sieve.

Step 5

Shake the sieve full of seeds lightly. This will bring the debris from the pod to the top and the seeds will filter to the bottom. Separate the seeds from the debris and place the seeds in a covered plastic container.

Step 6

Write the date and the color of the hollyhocks on a piece of masking tape and tape it to the plastic container. Store the container in the refrigerator until you are ready to plant your hollyhock seeds.
