Trouble getting pollen from Magic Carrousel

I’ve been trying to get pollen from ‘Magic Carrousel’ but it never seems to shed any. I’ve been picking the flowers that I expect to open that day and put them in a shady warm dry place in a bowl and still don’t get any pollen. Is this normal for MC? It looks like there should be lots. I’m having the same trouble with ‘Snow Carpet’. Looks like there should be lots of pollen but I’m getting none.
