I started with one pot of immortality in 2020 fall and it has consistently rebloom for me from May to November. I think it like my garden, lots of sunshine and lots of rainfall. I also has harvest of memories that boom the first season I planted and rebloom in the first season. But Harvest of Memories does not have good substance, form is not good. I would recommend Again and Again, which not only rebloom in my local public garden also has better form.
