Japanese Barberry: One Japanese Barberry!!
Larkspur: Two Spur!!
Nightshade: Nightshade! HAA-HA HA HA HA!!

1 Ok, this one is pretty much untranslatable. Plus I'm not sure I get it 100%.
There's a folk belief in Japan that if you see Mount Fuji, an eagle and an eggplant in your first dream of the new year, you'll have good luck in it.
As for the characters: I don't really know why Japanese Barberry (Megi) was dressed as the mountain, but the other two may have a connecting point.
Larkspur is dressed as a bird and says only the "Spur" so maybe the connection here is Lark (being a bird).
Nightshade's japanese name, Warunasubi, actually contains the word for eggplant, Nasu/Nasubi.
