If your dahlias go to seed, what to expect if you plant the seed?
I know that growers will allow their dahlias to produce seed to produce new hybrids, but they carefully control the process, making sure that the flowers are only pollinated by pollen from the flowers that they choose.
But if I allow my 7 closely growing dahlias to seed, without controlling where the pollen comes from, what would I expect if I grow those seeds next year?
Lets say a yellow flower is pollinated by a pink flower....Would it be safe to say that the resulting seeds will produce a pink and yellow flower that is in between the size of the 2 parent plants? What if pollen from more than one flower from different dahlias pollinates a single flower of another flower.... Will there be traits of 3 or more flower combined?
Have you tried this, and what was the result? Will most probably end up looking bad and maybe only a few will look OK?
