Wow, I have waited a long time for these "walking irises" to bloom so that I could remember what color they are! I walked outside to an awesome surprise tonight, N. longifolia in bloom with two flowers and a bud! Of course I got pics! Will add one when I feel like downloading them. Now I have to go get a label so I don't forget what it is when it is done blooming! They are called "walking irises" because after they bloom a small plantlet will grow at the end of the bloom stalk and when that plant gets big enough gravity will pull it down to the ground and that little plant will root out into the soil, thus "walking" :D
Ok, here it is!
