Yes it's D. linearis. I cultivate D. linearis on my Balcony in Berlin. Sown in January 2010. This summer, the first plant has bloomed. I have harvested 70 seeds.
They grow in pure peat. Very wet.
The hibernacula opened early in March - with ice, at -10 ° C at night. There was no problem, the plants looked healthy.
They grow slowly in spring and quickly on hot summer days.
In Canada, you should have no problems.
