If you didn't know this teeny tiny little factoid about me, the Dutch Iris is my favorite flower. *Especially* the deep purple colored ones. Good thing I planted 120+ of them around my yard this year. However....too bad I chose the variety bulb packs and the majority of them appear to be the white.

I really like Iris's too! I guess if you don't really like the white ones
you could put some kind of marker right next to them like a small stone or
popcicle stick and when the timing is right you could dig up the bulbs and
plant some you know you'd like in that spot instead. You might want to
group all your white ones in a different area in the yard and maybe you'd
like them better around a bird bath or something like that or else you
could simply give away the white bulbs to someone else.
