Part of my purchase decision for both daylilies and irises is name based. So I will buy things with SF or certain (literary) fantasy themes, or those with family or friend names, or those pertaining to attributes or interests of family or friends (or myself), or those that remind me of places that I have visited (or lived), or perhaps a song, and so on.
In the iris world, for some quick examples, the following have made their way into my garden based on their names: LOVELY LOIS, LORD JEFF, SARA'S BEAUTY, WEDDING KISS, ONE LAST KISS, PASSIONATE KISSES
, BOTTLE ROCKET, TOTAL RECALL, UNCLE CHARLIE, GAME PLAYER, PURPLE PEOPLE EATER, POEM OF LOVE, GLACIER POINT, PRINCESS BRIDE, HELLO DARKNESS.
In the daylily world, some daylilies that were chosen largely if not entirely for their name: SEARS TOWER, DECEMBER WEDDING, WINTER WEDDING, FOR LOIS, LOMA PRIETA, SACRAMENT OF HEALING, APRIL FOOLS, STARS MY DESTINATION.
Of course, sometimes a plant has a great (or meaningful) name, but it turns out to either be a bad plant (for your garden), or just not to your taste. (I won't name a certain popular iris that I gave away this summer - because in person, it was not to either my, or DH's, taste.)
Sometimes the plant may not be a great plant (not truly horrible, just not really good), but the name association is powerful enough that the plant stays.
But sometimes you luck out, and a plant that you bought pretty much solely for the name, turns out to be a great garden plant (for you, anyway).
