Those are some lovely pelargonium. I wish they did well here in Seward. Our climate is pretty wet and cool for them, but I just love a clay pot of bright red ones! The ivy varieties are lovely draping in baskets, too. I started several varieties of pelargonium under lights in my basement this winter. I had to start them in December in order to have them in bud by June, but I sold every one! I had planned to save a couple for myself, but forgot, but it is just as well, since we haven't had the weather for them to do well.
I'm not very smart about pelargoniums. I started the Ringo series from seed because I could purchase individual colors and they were supposed to be early bloomers. Our season is short here. I believe they are also zonal, so the pretty leaves make it easier to wait for blooms. I'll have to check to see if I can order seeds for the Regals.
