Dahlias grown from seed will not be true to the bloom they were collected from! They will be genetically similar but a complete surprise! All the seeds in our mixes were collected in our field of fully double blooms and grown separately from any seedlings we grow for ourselves. One of the main genetic traits for dahlias are “open centers” which are quite common. However, starting with seeds from fully double blooms gives that much more of a chance for a double bloom beauty. Some of the seed parents in our Mixed Seed packet are: Bracken Rose, Black Satin, Seabeck Shirley, Skipley Spot of Gold, Boom Boom White, KA Mocha Katie, Cosytown Gale, 20th Ave Gwen, Darcy, and many more! Our seed is hand sorted and selected and as such, you might find the occasional chaff or thinner seed.
A note on germination:
Dahlias are notorious for poor/low germination rates. While we have tested our mixes with good results, we can not guarantee a certain percentage will germinate.

We recommend the paper towel method for germination. Lay seeds out on a lightly damp paper towel (we prefer shop towels as the fibers are denser and hold moisture longer). Fold over the paper towel, being sure the seeds are separated and store in a zip top plastic bag. Dahlia seeds germinate at different rates but expect anywhere from 3-20 days with most germinating in 5-10 days. Dahlias do not need light to germinate and prefer temps of 65-70 degrees. Once you see a little taproot forming, you can carefully transfer the seed to a cell tray, covering over no more than 1/4” with a quality potting mix. We like Dirtcraft Organics, Fox Farm CocoLoco, or ProMix. Since the size of each seed can vary from variety to variety, bury the seed the same depth as the length of the seed. Start your seeds anywhere from 3-6 weeks before your last frost date. Typically we start our dahlia seeds 6-7 weeks before our last frost date as we like to transplant them out of the cell trays and into 4” pots to grow a little larger before planting out.
