I've gone for slug resistant plants

It seems a battle too hard to win, so I've researched for lists of mollusc resistant plants: things like strong smell, so taste unpleasant for them, harder, hairier leaves etc. We've bred plants but in some cases bred out their natural defences. 
The telegraph amongst others has a long list as well as the RHS. It's been very successful and I have a nice variety of plants in. The only dodgy one I tried was a coreopsis: front garden fine , back garden only one of four survived and I think it is snails as we have a lot of them this year. I've started planting geranium macrorrhizum around the garden to discourage them and also around the delphiniums which I seem to get going in my front garden; The front garden has gravel and I wonder if this discourages them. 

I haven't used metaldehyde pellets for years and have stopped using the iron/ aluminium pellets; it can't be a nice death. Also some are cannibalistic and dead ones attract others. I have used the nematodes which seems a natural process so I'm happier abut using them. I think the slug rings (with a turned over edge are fairly successful) and I started using  Grazers spray which makes the plants taste unpleasant. Overall I am pleased with my results and it makes the garden feel more in tune with nature

    Geranium macrorrhizums are marvellous ground cover plants but they produce an unfortunate side effect which you should be made aware of... they hide snails and slugs.. they find their large leafage a great shelter from which to launch their nightly attacks on your more favoured plantings... 

    As much as I love these Geraniums I do not use them anywhere near plants that are susceptible to mollusc attack...

    Coreopsis moonbeam is fine once it gets to a couple of inches each spring and then  they leave it alone. Before that, they eat it to ground level so you think youve lost the plant
    I dont know about other coreopsis.
    In London. Keen but lazy.
  • "Red Elf" is fine,i've had small cuttings of this one,and the slugs haven't bothered.

    I gave up on lots of slug fodder decades ago. I had neither the time, energy or inclination to keep faffing around trying to keep them alive. 

    The few plants I grow that slugs/snails like make it easier to keep on top of them. 

    Gravel in itself isn't that much of a deterrent. I have gravel paths which they happily crawl across, and they also have no problem climbing the house walls, which are covered in crushed shell.  :)
    It's a place where beautiful isn't enough of a word....

    I live in west central Scotland - not where that photo is...

    Ok thanks Marlorena, I had the idea that the strong smell of the foliage would dissuade them; I'm non too fond of the smell myself, but the plant certainly keeps the weeds down, fills shady spots, has delicate flowers visited by insects, but no good for keeping the slugs away then ?

    My punk slugs love garlic plants and have just razed two large fennels to the ground.
