Yes, there's a broken branch - it's where I was checking to see if the sap was still green. But the whole plant looks like that too.
I've dug up one of the shrivelled plants - and the earth underneath and around it wasn't dry - just nicely moist - and the foxgloves and hebe nearby are doing fine. The dug up plant showed roots that were dead too...in fact the whole thing was dead. It's a mystery. No sign of weevils or any bugs eating the roots...just dried up and shrivelled.
