I've owned several sago palm houseplants over the years. Mostly they just sit around and do absolutely nothing for years on end, being so boring as to either make you forget to water them or decide they are dead and throw them away.
But they're architectural and non-messy, so I like them despite their boringness.

Recently in my world of ownership of two boring sago palms, however, A DEVELOPMENT!

That is a new set of leaves!
Holy crap, and yikes. I'm thrilled one of my pair of palms actually did something, but I'm not sure I'm on board with this whole tripling in size thing. I seem to be having an issue with houseplants bossing me around lately, just ask the 14+ foot bird of paradise and anyone who has paid my living area a visit recently.
Anyway, how weird that these new leaves are completely different than the existing leaves in their appearance. I assume this is due to the conditions here at Modern in MN vs. those of wherever it lived before I was it's momma, but still....very strange, in a prehistoric, Invasion of the Body Snatchers kind of way.
