Mr. Subjunctive from Plants are the Strangest People sends along a funny.
This is growing on E Washington St. in Washington, IA; the photo was taken 26 March 2012. I’ve seen it on previous trips as well, and thought of y’all, but things hadn’t worked out to take a picture of it, and we don’t actually go to Washington that often.
I think the bloom is new since the last time I saw it. Both the color (black?!) and form (more like an aroid flower than a cactus flower, really) are noteworthy. I presume, based on the bloom, that this is a Discocactus of some sort? It’s a slow grower, but I suppose that’s to be expected for any Iowa cacti.
First you need to click the picture above to get a closer look at the details. And then, here’s a Discocactus in bloom, so we can judge the similarities and determine the species.
