Q.Cyclamen blooming well – despite not having any leaves!
I’ve had this particular (indoor) Cyclamen plant for exactly 1 year now … and despite the fact that it has no leaves at all, it is continuing to bloom with plenty of lovely flowers! Currently there are 27 flowers fully open, and a further 6 buds. Is this unusual?

Yes, that is very unusual. Since it's doing so well, I wouldn't change any of your cultural practices, but when the flowers start to fail, you might want to let it go dormant for a couple of months, then see if it will regrow leaves. https://www.gardeningknowhow.com/houseplants/cyclamen/cyclamen-care.htm
