My cactus, that I’ve had for fifteen years or so. It has suffered a few indignities: being pinched in a too-small pot, being chewed by squirrels, having its needles bitten off by chipmunks. This year the cactus is making only one flower (last year, two), but—a complete surprise—it has started a tiny arm. I thought all along it was a barrel-type cactus, but it may be more akin to a saguaro.
A venus flytrap I bought at Walmart, just to add another item to my pitcher plant tub. But it stuck up a flower head, and this is what the flower looks like.
