Thanks Verdun and Julie, interesting. I'm definitely on free draining soil, so that is one good thing.
If I remove the flowers before mid summer, I assume they will still flower later on this year ?
If they only last that long 2 -3 years, do you rely on them reseeding to keep up numbers or are people / places growing them from seed year. I thought I'd purchased a bargain, but it seems these could be some high maintenance plants.
Any advice on how you get a decent clump growing and keep them in the garden. Maybe I should stick with the Purpurea and Magnus in future.
Always learning, sorry for the daft questions.
