We got a huge bag of 1,000 Oxalis triangularis pips donated almost a year ago. They've been sitting in the cooler this whole time, but they still look viable. Some of them even have tiny light-starved shoots growing out of them.
They sold really well in last year's sale, so I potted some up for this year's sale. We can market these as both a houseplant and an annual, so I'm growing two batch for the two different displays.
I'm not sure if "pip" is the correct word, but that's what I've always heard these worm-like roots called. I also heard citrus and apple seeds called pips, so maybe it's just a general word for small seed-like thingy.
