Where to start Trillium grandiflora & erectum???
I have potted up the 8 trillium bulbs which I got from Walmart. Im not sure if I should keep them in the house or in my unheated garage. I am located in Edmonton and not sure if the garage goes below freezing at night anymore. Has anyone grown these species??? How do they fair in the prairies or other zone 3s? Should I leave them in the garage or bring them in? And when should I plant them in the ground??? Thanks.
