I was floored to see this at one of the local plant shops! (If you’re in Seattle, please visit the Indoor Sun Shoppe. They have so many weird plant beebs that aren’t being sold!)
This is Oxalis gigantea, which as the name suggests, is a giant, shrub-like form of Oxalis. In general I’ve really been getting into the more exotic Oxalis species and had been wanting this one but, it’s been tricky to find online and in stock.
I took one of the larger planters and put the Oxalis palmifrons in it as well to create a desert Oxalis planter!
