I'm writing in one of my few waking moments, which means, in turns, that I am not making much progress on my first horticulture lesson, which is about plant classification and nomenclature.
"What's in a name? That which we call a rose by any other name would smell as sweet."
Alas it rings so true while trying to memorize plant variants on a headache!
P.S. As you can see, my graph is a bit of a battlefield and took one week to put together (in my present condition), but I think I have captured most of the concepts that needed capturing... Oh, no, just realised I have forgotten something: a list of the 6 plant's features: chlorophyll, roots, leaves, stems, flowers, seeds.
