I love Baby Boomer too.. It bloomed for the first time last year, but it only had a couple of buds. This year it is doing much better.
Jan, you are correct, Karen Newman is his US distributor. She is also his test grower for the States. She does send great plants. I don't have either one of those that you mentioned. I do have a few others of his, but I don't think that they are part of the WWI memorial series. Glad that your Charles Johnson survived the winter. Mine bloomed a long time last year. Hope yours does equally as well.
