I was gently reminded by a couple of perfumer friends that plants can also be depicted in an olfactory manner. So olfactory depictions (ie: perfumes) are another way to express your love of plants. Of course, I don't recommend using the scent of Senecio flowers...or hoodias.... And music/soundscapes are another great idea. Or combine all the senses in one work, there's a challenge! But I'm not going to attempt that challenge just yet.
