now that the irises shown below have finished the muscari is now the focus of this rack of pots, outside the muscari are blooming as well (pic to follow), there's no forcing these, muscari will bloom when they are good and ready! regardless of M+S and other shops selling them as forcing bulbs

a whole view of the plants shown in the close-up above
crocus blooms after they've been inside on the windowsill a couple days
a period outside has helped these bulbs, the hyacinth has a second bloom and the crocus has a couple more buds ready to open
some time outside and then being brought inside has forced these irises to bloom, as well as the crocus
