Or is it possible I’m just impatient and she’s not ready to bloom. The smaller one already blooming made me concerned

Not sure where you are, but I'm in SE Michigan, zone 5b/6a, and no blooms yet on my Rozanne, which is normal. :-)

I gave up on my Rozannes and gave them away. I found they were great the first few years and then I had very few blooms in relation to the size of the plant. i divided it 2 summers ago and last year it was the same -skimpy in the bloom department. Mine was in full sun, maybe it didn’t really like it. I’m in Ontario zone 4b

I moved my Johnson’s Blue into a “rough” bed to put in the Rozannes because I thought the Rozannes were more exciting. But now I like the Johnson’s Blue better (so fickle -lol) and have divided the clump and put them where the Rozanne’s were

My Rozannes aren't blooming yet either. I think Rozanne is one of the latest geraniums to emerge in spring and then bloom. I think I see little buds coming up in yours so give it a little time.

I think it is early days yet. If you can figure out how to add your zone it would be helpful to get info from people in similar climates. Many other geraniums are blooming, but Rozanne was always about two weeks later. I'm sure of it.

Mine is now about 3 feet tall with 1 flower...

Here Rozanne starts around July 1st and keeps going for the rest of the summer. I used to have several of them, but I found her a difficult plant to keep happy. Only one left, growing on the north side where it gets some morning sun and I think afternoon shade.

Roxanne is a summer bloomer while many of the other perennial Geraniums are spring bloomers. I have several kinds of spring blooming Geraniums , but I really like Rozanne because it blooms at a time that my garden has fewer blooms and so it helps fill the gap.
