Aside from a damping-off preventer I have sometimes used for indoor seed beds, slug bait is the one synthetic thing I don't mind using around plants. Chemical fertilizers and insecticides are a no go, but experience with slugs eating seedlings is painful enough to be grateful for slug bait. I know, I know, there's probably a million methods to kill slugs. I'll clinch on a natural method sooner or later I'm sure, but for now convenience wins out. Anyways, it's a flaky substance; not the kind of thing to get everywhere and poison things.
The Japanese Cobra Lily seeds (Arisaema sikokianum) that I had in their baggie doing a warm startification sprouted, twelve of them, around two or three weeks in. And without their cold stratification. That's what I like. Growing it from seed though, it will be years before I get to see the likes of this.
All eleven of those mystery seeds (picture below) have sprouted.
To which I've revised the riddle (I know, how lame):
Never in my lifetime will you prune me.
I take care of my shape well enough;
besides, though thornless, my leaves are so tough
and lance-like, that I'm sure you will agree,
the merest eyesight will inform the most dumb:
one foot at closest, round my parameter,
is an excellent rule of thumb.
