Finally, some new leaves popping up deep in the core. So all appears well.

So a full year after I first noticed some small activity in the resuscitated core, there is evidence of "normal" growth. I expected this a year ago, but it just sat and did nothing last year after reacting to the onset of spring by generating a small flush a cm or two long, apparently still dealing with consequences of the severe rot that nearly killed it 2.5 years ago.

OTOH, I don't want to get ahead of myself. The center of the plant now looks like it should and is definitely growing, but there is still no way to tell where this is heading. Fingers crossed for no more surprises.

Another notable update in the continuing saga of my zombie Dasy. I now see (well sorta) why this plant sat seemingly dormant for nearly all of last year after initially developing a small flush deep in the core. That core is no longer active, and the new flush shown is from a new core. Well, that isn't exactly right either. It isn't an entirely new core. It looks to me as if the original core split in two (branched), now with one active (front) and one inactive (behind) core.

Does that make sense? This plant is a trip. New flush is growing vigorously.

Given its recovery to date, I think the plant is OK and will grow and produce new leaves on its own schedule. Just an opinion.

I'm not so sure it's OK. It's clearly working toward that end, but I would breathe a little easier if it would just settle into some level of "normal".

My surviving Dasylirion quadrangulatum takes core damage like that every winter here, and I cover it or take it in for the worst of the weather. It survives though and I’ve seen huge specimen around town that seemed to do better.

As you can see from snaps here, there is nothing normal about this -- aside from the fact that Dasys don't normally produce large flushes like this at all, instead deferring to a slow steady stream of individual leaves. This new flush has a dramatic lean to it, rather than coming straight up as it should. If anything, the lean is even more dramatic than indicated by snaps.

Could this "cycad" flush be caused by the rot preventing new leaves to come out? They may have accumulated until the rot problem got sorted and instead of going one by one they are all pushed out at once. Just a guess, really.
Regarding its leaning, you wrote it now has two cores. Wouldn't they try to point away from each other? Another guess.

Sure, something like that. Tho the new flush is leaning toward the now defunct core, rather than away from it. This has all been going on for a long time now, and the second time it produced a large flush. Also, we're now experiencing the same kind of extended heat spell that led to its near demise three years ago. It has all been very interesting, but more and more, I doubt it's ever going to truly recover.

The Dasy that wouldn't die. This is the third new growth point it's formed over the past few years. This one looks a little screwy, but it's green and growing. Sadly, it is also likely to pass from excessive heat this summer. Fingers crossed.

Ron, can you get close into the spoon to take a picture? I'm wondering if it might be D. longissimum, rather than quadrangulatum. Not that it makes any practical difference other than what to write on the headstone :D

Not exactly sure what you want to see that you haven't already. Clarify or post a sample snap to emulate.

This sort of thing.

BTW, I also tried a smallish Dasy longo a little while back and it was dead as a door nail within about three weeks of things heating up. Unfortunately, these entirely desirable Dasys are entirely ill-suited to the current ravages of summer here. There used to be several other Dasy quads along my street. All died during the same summer that first took mine out.
