They will all flower if conditions are just right for the species. Some are harder to bring to flower, but give them losts water in the spring, rain water is especially great for them. I have several in flower at this time of the year, and for some reason
Sept. is the best month for flowering for me. That rosette will not flower again, but it will put out a lot of babies if you let it and they should flower. The neglect did it, it is celebrating it's new life. This flowering rosette will not die, it will just produce new plants for you. Congratulations. Norma
