Beginner Gardening: What Datura species is this?, 1 by thetripscaptain

I bought and grew some seeds this year, which the seller told me were the white-flowered Datura metel. Searching through online pictures has just confused me, as I think alot of them are misidentified. After reading some general descriptions I wonder if my plant is, in fact, something else.

Here is as detalied a description as I can give:

The stem is bright purple, with a texture like it has been sanded with sandpaper.

The leaves are thick, velvety, and dark blue-green with off-white veins that are very pronounced. When small, the leaves are not serated but they develop some as they grow. The serrations are very rounded, and are more like two small lumps on either side of the leaf towards the stem side. (I know that's a crappy description... pictures will be included.

The flower is white, sometimes with a blueish-purpleish tint at the rim. It has ten "folds" but only five "teeth" on the outside of the flower. The outside of the flower has green veins down by the calyx.

The seed pod hangs downwards, and is covered in spikes.
