I live now in the North of Spain so very familiar with it. I actually do not know how to grow one though, just seen them hanging on doors
And some blue ones in Nature
My Eguzkilore is going to bloom soon. According to Basque mitology it protects homes from evil spirits. https://www.amalur-zen.com/blog/eguzkilore/

the blue ones must be very beautiful 😍 not sure what the secret is, been trying to grow one for years and this is my first success. i think i found the right spot: plenty of sunlight and in a windy side of the garden.
