So the Dracaena fragrans 'Sol' that I've had since February 2008 has produced a sucker.
This is the first time I've seen a D. fragrans do this, and I actually had kind of forgot that it was even a possibility, so this was a nice surprise.
That said, I'm not really sure what to do about it; at one point, the prospect of having propagatable material for this plant would have been fantastic, exciting news, but now? Not so much. Of all the plants to have more of, Dracaenas are way too big to be very high on my list. So the plan is basically to leave it alone and see what happens. Which is a plan I've been falling back on quite a lot lately.
