This week, it was the Surprise Lilies (Lycoris squamigera) that prompted the onset of the mental gymnastics. They've been in my garden a number of years and they never fail to surprise and delight me, as they have yet again this season. Sometimes, in the spring, I'll see the daylily-like foliage and have to think a minute to remember not to weed it out, but I've spread these so they now pop up several places in the garden. Whether my next garden is 10 acres or 10 square feet, I always want these Naked Ladies (their other, less politically-correct name) to pop up and delight me.
Unless, of course, it grew feet and walked. Sometimes plants try to sneak past an inattentive gardener.
