Harvesting Dahlia Seeds

This year at the rental house I grew Dahlias in pots, started from seed back in March/April. Now they are starting to die back, and the flower heads are ready to be harvested for seeds, so I can grow more next year. This was my first year growing Dahlias; now that I am in Washington, I can grow them in the ground and leave them over the winter because the winters here are so much milder than in Massachusetts. I was not interested in growing them back East, because they would have needed to be dug up every autumn  and replanted in the spring. I'm too lazy for all that work!

Anyway, I popped the spent flowers off the tips of the stems, and stored them overnight in a cabinet, hoping they might dry out a bit. They didn't, but I decided to harvest the seeds from them anyway.

Here is a picture of the spent flowers:

Here's what the mature seeds inside looked like, once they were separated from the chaff:

The term chaff is a botanical term meaning "all the useless bits." When I first opened the flower head, the seeds were still connected to the chaff. I needed to separate them, so they could dry out and be stored without getting moldy. When I first separated the seeds, they were waxy and a bit slimy.  They tended to stick together, to each other, to the chaff, to my fingers, to the plate.... They looked like this:

I just fanned them out and picked them apart. Some flower heads had a lot of seeds, some had only a few. Sometimes they were all around the outside edge of the flower, sometimes they were in a cluster in the center. It was a treasure hunt.

Sometimes there were what I think of as "fake me out" seeds. They look sort of like seeds, but not as big, and they didn't have that thicker part on one end.

They look like seeds, don't they? But here they are next to the real seeds:

These seeds are from the pretty red and white Dahlia, called 'Harlequin', that is pictured at the top of the page with my title. I also saved seeds from a yellow and pink one, a red one, and a streaky red, pink and white one. I want to grow loads of these next year in my new garden.


  1. so they can be in the center I havent been able to find any on my dahlia???

    1. Yes, the seeds should be in the center of the dried flowers, but not all dahlias have seeds. Some of the very fancy ones don't have any seeds, or they have only one or two.

    2. OK Thanks but are the ones in the center like the pics

    3. The seeds in the pictures came from the the dried flower head, not necessarily from just the center, but from all around inside it. Hope that helps. If you basically just take the whole thing apart, you should see them. If you don't see anything that looks like these pictures, then the dried flower head is sterile and has no seeds.

  2. I hope you can help me ,Iv been surching for days and when I say days I mean Days, the cinter I thought was the just the center of the flower can they hold the seeds

  3. one more questind,does the cenyer seeds look lkie the pic too?

  4. does the center seeds look like the seeds in the pic


Gardening is a solitary activity. But blogging about it is a social phenomenon! I don't make money from my blog by advertising, or use it to drive customers to a business. If you liked my post, or my writing or photography, or even just one picture or turn of phrase, I'd love to hear from you. That's how I get paid.
