It's took a few days to gather the supplies, but my birthday succulents are now happily planted in well-draining soil and ensconced in a planter holder outside my office window. Shockingly (to me) this pot is the only of my 15 potted plants that has more than one species of plant in it! I really need to branch out with my planting strategies. Unfortunately, I've run out of surface area near windows on which to set more potted plants, so I'm stuck with the current arrangement for the time being. (Eventually I will live somewhere that has windows on more than one side of the building. And, while I'm wishing, more than one door so the place isn't a total fire trap.)
I think that my arrangement, while simple, turned out rather cute.
