An observation

Over the past 10 years or so I have noticed that the Bishop of Llandaff and his seed sown progeny, viz., Bishop’s Children, seem both more robust and more slug resistant than other dahlias!

Some dahlias here are over 6’ incl one or two of the above and they have not needed staking. They are rarely attacked by slugs/ snails. Anyone else aware of this?

It does not necessarily apply to all purple foliage dahlias....the Bishop of York for example does not seem resistant......but Twynings After Eight also seems less attractive to the molluscs and sturdier in growth.

Probably others will voice the opposite view but, here at any rate, this is the case. It means in practice I can save time and energy in not staking The Bishop and his clan

 

That's interesting @Verdun ...As a chicken keeper who has free roaming rights will not touch Dark /purple foliage..there must be something that puts them off.

 

I have Bishop of Dover beside ARt Deco with a Bishops Children at the rear.

Guess which one has suffered most from slug damage.

Can’t seem to turn the picture the right way round!
