<<  Specifically, I mean to find which species or cultivars of hosta

 with leaf thickness.  Would you agree, or can you think of another

I don't think the thickness of the leaf is a factor. If you will notice, a,
say, H.'Puckered Giant', the leaves of which are quite thick, slugs will
nibble away at it.
To be sure, I have never seen any slug damage on my 'Sum and Substance';yet,
'Invincible' is prime slug bait here. There are also some rather "thinned-
leaf" hostas that slugs avoid, even though similar hostas, in the same
vicinty, are eaten.
I think your experiment has a lot of merit. I have noticed that gold cum
chartruese hostas are avoided by slugs, no matter what the thickness of the
As far as other displays, what about showing leaves of hostas that are
"infected" by:
1. Slugs
2. Cutworms
3. Black Vine Weevils
4. Viruses
5. Foliar nematodes
6. Cholrosis
7. Anathracnose
8. Crown Rot (Fungus)
9. Lack of Water
10. Genetic "browning" of leaves.
11. Sun scalding
12. Sowbugs

AND then have at each display, have a chart of the remedies.

Good Luck! And Best Wishes!

P.S. If you do the one with slugs, it would be nice to have either depictions
of slugs or several of the more common species of slugs in fomaldehyde.
