I believe it is totally fine to choose a plant because its name resonates with you. I planted Blue Jacket hyacinths on the grave of my father-in-law, who was on the first ship hit at Pearl Harbor. I sent an assortment of daylilies with names like “Crimson Pirate” to my nephew, a then budding gardener. (My gifts are usually spot-on, but a box of roots did not thrill the young boy. His mother (my sister) did love them for years until something the guy truly did want – dogs – dug them up. Such is life.)
So when I decided to add to my iris collection Goodnight Moon was too sweet of a name to pass up. Now this plant has been divided a couple times, with one rhizome going to friend who raves about it every spring. Last year I moved a few rhizomes into a new bed by our deck and this spring it is reminding me why Goodnight Moon is my favorite iris. As I write this, she stands about three feet tall with at least five blooms. Although each bloom does not last long, they are so huge and numerous that this iris has been a show-stopper for quite some time. And, being an iris, no deer repellent has been needed.
That deer resistant foliage is a great addition to the garden even when the blooms have gone. I think that once you cut back the stem, the linear, upright leaves add an architectural accent to the planting bed. And in a few years you can divide the iris and add that accent throughout your garden.
