There's also O. corniculata that looks similar, and probably others. But yeah, I mulched, watered, fertilized that plant... probably deadheaded it. LOL! A little taller than sources say it gets, but who else has pampered that plant to see such results? It was probably a 2nd year plant, not a new sprout from that year.
It's possible some or all of the sprouts I've been pulling here in AL are O. corniculata or dillenii. I haven't let any of them grow enough to notice a possible difference. If I notice it's not a bulb Oxalis leaf, out it comes.
