three years ago i bought digitalis saltwood summer. It was planted in my raised border in a general peat based compost. for the first year i kept it well watered and last year it flowered beautifully, but this year there was hardly any leaves and i had 6 flower stalks and they werent up to much. Now it has died completely,with no signs of any leaves at all. It got the sun all day, but the weather this year in the highlands hasnt been great and im wondering if the cold wet summer finished it off and should i try and get another one.
