"Nyctinasty (nyc = night or darkness, nastic = firm or pressed close) is the specific movement of leaves or flowers in a daily pattern, open during the day and closed at night. Nyctinastic movements are accomplished by the flow of water in and out of specific cells in the pulvini (swellings, singular is pulvinus) at the base of the petioles (the stalk that attaches the leaf blade to the stem). It is not unlike our muscle movements in that there is an extensor and a flexor pair. When K+ and Cl- are pumped into the extensor cells on the bottom of the pulvini, they become hypertonic and water follows the ions through osmosis. This causes the extensor cells to swell due to increased turgor pressure." - http://biologicalexceptions.blogspot.com/2011/11/plants-that-dont-sleep-will-take-dirt.html "A pulvinus is also sometimes called a geniculum." - https://www.boundless.com/biology/definition/pulvini/

Do add to fofoca's great advice, "Be careful not to overwater while it's recovering" which was an awsome point, please don't miss it.. Then, to see the roots recover quickly, make sure when you pot it, to put in an open, loose, airy well draining soiless mix. The looser the soil, and the faster draining it is, the more likely you will avoid future root rot problems and let your roots breathe as soon as possible. Good air exchange and quicker drying out of mix, if you do so..Your roots will thank you for it! You want your soiless mix to dry out at least every couple of days. For some here, that is still to long to wait..For some, to much of a hassel to HAVE to water so frequently. Your plants will LOVE you for this too..lol Remember, the first most important thing is, the soiless mix you'll be using, then everything will follow to your benefit..:-) Happy growing and I hope everything goes well..

I looked all these latest suggestions up and Foxtail Lily is almost exactly what I saw! I remember the leaves as being different but I WAS looking at them as I was driving by. I did get the feeling it was a bulb of some sort. Woo hoo, I think you may have done it Christie!
