I don't consider myself a novice gardener but apparently I am when it comes to iris. My mom gave me several rhizomes last summer, one had a spent stalk on it, no leaves. I planted it along with the others, occasionally checking for growth. After 6 months of nothing, no rot, no roots, no leaves I did a search. Well well after a mother blooms that's it for that rhizome? When dividing, discard the mother bulb and keep the daughters? I know when I found this information I actually said what?! out loud. I need to check in with y'all more often!
