LydiaIvy. I am not fond of Ivy because it reminds me of IV (and I'm terrified of needles) and because the plant is essentially a weed which does massive, damage to buildings and forests.
Ivy is such an annoying plant, and I don't like the way it starts with I. Same as Megan sometimes starts with Me!So, though I find Lydia pretentious, I'd go for LydiaIvy any time.
