Most of my garden is in sun to be honest but try them and see. I just stuck seeds straight in the ground and they have taken! Singer self seeded onto a cover matting last year and have rooted there so they are easy! Try and see! 😃
Wow! Its exciting to see what colour they'll be. Seem to remember their natural colour is purple. Maybe they revert back? Not such a bad thing ;) mine never go to seed, I always chop them at the first sign of going to seed, to force more flower production.
We've found that if there grown on the boarder at the back of the garden they die ( to hot ) but if there grown in the semi shade boarder they do very very as long as there roots are kept damp & there feed well lupins are my absolute favourite plant hope that helps @junebensted 😍😍😍
