I now have a weelbarrow full
I now have a weelbarrow full of dahlia tubors from 3 years of growing. Started with about 30 from my mother. Both she and I have had the same problem. The colored ones seem to all become white in subsequest years. We have added new varieties and they all seem to eventually become the same variety. Are there more dominant varieties / colors that take over the genetics? By the way, the all seem to become white as years go by. Odd
