Found new information on my Dark Red Blizzard pelargonium. You can read the updates on its page on the Garden Image site. I will also update the pages of the White and Blue Blizzards.
The US Plant Patent pages on Google have all the information I've been searching for. Now I will be able to include the breeder's name and origin. Also added a source from the UK. Can't find an online source for the US right now. But you might be able to find it at your local nursery soon.
Will be adding Lulumex, trade name: Picasso. Started them from seed and they are coming along nicely.
