I just renewed my membership for the second year. Last year I was told I could get some seeds but by the time I got a password, it was too late. This year I will try again. I live east of Sault Ste. Marie Ontario near Iron Bridge. I have a large piece of land (160 acres) but it is prone to flooding. The soil is silt over clay and gravel or bed rock. Soil pH is 5.5.
I have lived here 2 years and have killed tulips, rotted potatoes and tomatoes from the Fall moisture in a short growing season (zone 4). I have good snow cover but too much moisture when it all melts in the Spring. Summer nights are cool but there is lots of sun and good breezes.

My question is: what seeds should I order which might be successful. Because my nearest town has a population of only 900 people, landscaping supplies are not readily available so it isn't even easy to create a raised bed. I do have some plants which are doing very well including Iris cristata and even some Dianthus which I didn't think liked acid soil. I tend to like blue, pink and red flowers best.
