Helwingia japonica (chinensis broadleaf)

Rates an 11 on the weird meter, a cornaceous shrub in which the flowers are born from the center of the leaves, actually they're not, it just looks that way but that's another story. More of a curiosity than an outstanding ornamental plant, it's great for playing stump the botanist, they'll never even guess the family; and if worst comes to worst you can always eat it, they do in Japan, (it'll never replace lettuce).
