March 22 and this one is just starting to bloom in the alpine house at our Botanical Garden..another new early record. It will certainly be long gone before we open to the public for the season on May 1! Lovely fragrance on this one.
Have you tried this in your garden? I know some people in northern Norway growing this outdoors although I have never seen it myself.
It grows very easily outdoors here. I had one out in the front yard in unimproved clay (though on a slope) for many years... I've had one in a trough now for a long time too; unfortunately, in the last 2 years, the jackrabbits have discovered it and tend to munch the flowers off!
I have not tried it outside but we have 3 in the alpine house so I could easily move one to the crevice garden...it is a useless plant for the public to see since even in a cold spring, the plants are faded before we open to the public on May 1. Maybe outside the blooming will be delayed so the public COULD see it!
