Jen, the trick with buying them from Menards is to get them early enough. I bought some last year, when they were on sale half off (which they should be going on sale soon, I would guess, so watch for that!) and all of mine grew EXCEPT the deep burgandy one, which was the one I really wanted the most. BUT, if they have growth, they WILL grow! The problem is that people peek inside to see if they have growth, then don't close up the bag, and it needs to stay moist, so they get dried out and die. Stupid people. LOL But, yours looks very nice and will grow for sure. I would suggest that you put it in a larger pot right off the bat, though. This spring, my pots that they came in were split and tubers were growing out the top and the sides and everywhere else. It makes it harder to get them out of the pot later. Just a thought. I took a 3.5 gal bucket, cut off the bottom about 5" high, put cat litter (regular clay, unscented, NOT the scoopable type be sure!) and popped the tubers into that. Put some bigger rocks around it to keep the koi from digging, then go ahead and put it down where you want it. I put mine in those little pots at about 18" an they did fine. If you are putting them 3', then do it slower, though. Good luck! I'll be VERY jealous if you get a really deep red like the pic! I'm watching for them to go on sale (maybe Memorial Day weekend ...) and going to try to get a good red one then. Otherwise, I have plenty of lilys. LOL
Oh almost forgot, your pink lily is really beautiful! Looks almost like a double, so many petals. Gorgeous!!!
