Dalia sorensenii is a wild relative of the common garden dahlia and probably one of the two original parents of the garden dahlia, along with D. coccinea. Native range is higher elevations in central Mexico. Like many of the wild dahlias, it has pink/purple, star shaped, single flowers. Plants reach about six feet here, before the tops are killed by frost. Flowers at about the same time as garden dahlias.
None of our dahlias are grown on a spacing that precludes cross pollination between species. They aren’t right next to each other, so they will be reasonably pure, but there is always the possibility that you will get some seedlings that are inter-species crosses. To my way of thinking, that only adds extra value, but if you have a need for absolute purity in your seeds, these might not be what you are looking for.
