7.22.11 I'm always gratified when I find a good reason not to keep a weed-free garden; today I found three reasons! The Night-flowering Catchfly which left my fingers feeling very sticky after handling it; the Moth Mullein whose nickel-sized blossoms last but a day; and a pink Hemp-Nettle. Hemp-Nettle has white or pink blossoms, both with purple markings, protrusions from the lower petal that look like fangs, and hairy spikes on the upper petal. I don't know the name of the insect on the Hemp-Nettle, but it seemed more interested in the plant than its blossoms.
