I planted peonies (roots) this spring and they both grew up with one stem each and a few leaves. In September one of the stems died and disappeared. I don't know if that plant is dead or it's just resting for autumn. Strange thing, the other plant's stem is still up even right now! Is the stemless plant dead or resting? Should I dig it up and check? But I don't want to disturb it (if it's resting). But I'm quite curious to check on its condition... Thanks for any help! Oh, and the peony I'm talking about is the regular peony, not tree peony.
