Here are two of the darkest lilies growing in my garden. Night Flyer is another dark lily in my collection that unfortunately got eaten by a deer before it bloomed.
Landini, upfacing and does not open wide enough.
Dimension, some sellers call it Dimention.
Dimension, its orientation is also upfacing and it opens wide and the tip of the petals recurve a little bit.
Both of these lilies are Asiatic.
