A bit of colour

I like flowers but they’re not my strong suit. I’m more qualified to differentiate a Hereford from a Shorthorn or a Beagle from a Basset.
I called in at Graham and Bec’s today and thought these looked very photogenic but I’m undecided on whether it’s a Gladiolus or an Iris. I not too confident about the pink one in the background either, maybe a Dahlia or a Chrysanthemum.
It’s taken me 73 years to learn this much but I’m working on it.
