Oh I've done this with lavender on a sunny day and it's glorious! You actually have to draw fast-ish because the shadows keep moving, which gives you the added bonus of being reminded that the earth is revolving around the sun and we are all just insignificant motes of dust. Glorious. If it's not a sunny day, you can also do this: clip some branches, bring them inside, set them in a vase, set up a reading lamp (one with an angled neck) and cast a shadow on the wall. Tape your paper to the wall (use removable tape!) and trace away. You can get really interesting results by angling the lamp to create exaggerated shadows.
