Asiatic.

There were descriptions of the leaves and stalks that can help decide, but another way I have read about is the color. Asiatics are usually one solid color only and Orientals tend to (or maybe always do) have a mixed coloring.

The single coloration notwithstanding - the easiest distinguishing difference in Asiatic vs. Oriental lilies is the leafing.

On the Asiatics there are lots of slender leaves whirling/ bristling up the stalk. Orientals have fewer larger leaves which are more stem hugging.

There shouldn't be too much questioning that the lily in the OP's picture is an Asiatic.

Asiatic for sure
