I do not know why but I lost half of my lupines last winter which was a surprise because they are usually very hardy.
To my delight The Chatelaine (Lupinus ‘The Chatelaine’) started to bloom in the new spot that it was planted this spring.
I am still trying to find more colors. Lupines are so easy flowers for the summer cottage.

I like lupines. That is a very pretty one.

Beautiful. Planted lots of perennial lupines in Dec and have lots of plants but none are very large and no flowers in sight. Just one as lovely as yours would be a thrill.
