Hi Rebekka, This is a wonderful plant! Yesterday, I led a walk in Park Frankendael and can tell you that we have a lot there, currently in flower – the white and purple and in between – if you want to harvest in some quantity that could be challenging in your local park. They are in the Nettle Orchard – so the orchard closest to the terrace of Merkelbach Restaurant. The purple flowers are also the most dark-bright I have seen them in many years. This seems to be a very good Comfrey year.
