I've had a King Henry for the past few months that has been growing very vigorously. Soon after receiving it, it began producing a division at the oldest point on its rhizome, which I believe is the typical point from which divisions arise.
What has me puzzled is the sudden appearance of new growths directly on some of the youngest shoots of the rhizome. They began appearing over the past few days, and from what I can see, there's at least 4 of these new structures (I assume they're axillary buds). It seems pretty clear that they'll eventually develop into new shoots.
I'm curious if anyone might know exactly what these growths are, and how/why they're growing on such new areas of the rhizome? These amazing plants continue fascinating me, and it's clear I've got a lot more to learn.
