The bees love 'em
so do slugs and snails
I little trick I do to prolong the flowering time is when seed pods start to form but there's still lots of flower buds to open, I hold the top of the flower gently and rub the seedpods off. As most plants' aim in life is to reproduce, when it has made seeds then it decides it doesn't need to flower anymore, so by rubbing off the seeds I trick it into thinking it hasn't done its job. I get loads more flowers then. The end of the stalk looks a bit funny eventually (photo below) but it's worth it for more flowers. When I think the last flower spike comes along I let the pods stay on and use the seeds to make more plants and I always get some good colour combinations.
I would love to grow them but they seem to really dislike my heavy clay soil. Does anyone know if they do well in pots?
Just how 'short-lived' are they supposed to be ? I've had the same pink and white Lupin in my garden for over 9 years, and it's travelled to 3 different gardens with me. It's now found it's forever home, so I'll be disappointed if it suddenly decides to die, as it's going great-guns this year I too love to see the bumblies on the flowers, the way they settle on the bottom of the flower and it just drops down so they can get inside to all the goodies is fascinating to watch.
