I would look for different types of "leaf lettuces" instead of head types.
Arugula, spinach, red sails, mustard (southern giant curled), chicoree, red
summer crisp(sierra), red oakleaf, winter density, radicchio and crispy
frills are just a few I've grown with success in the past.

I usually find seed packages in hardware stores or garden centers. I just
choose ones that look interesting and grow them. So far, I haven't been
disappointed. The spinach and red leaf types are my favorite. Arugula was
my absolute favorite until I discovered I am prone to allergic reactions
from eating it. It's the only thing in the entire world that I'm allergic
go - go figure. Now I grow lots of mustard greens to mix into salads for
some spice.

Hope this answers some of your questions. Good luck.

We are planning on planting vegetables again this summer now that our dogs
are older and will leave the plot alone. We live in the Niagara, Canada
area - very hot and humid summers (it's a fruit belt region) and very cold
winters.

I am looking for advice on growing different greens - specifically for
salads, like the Spring Mix they sell at the grocery stores. I am only
familiar with the usual run of the mill greens like iceberg, romaine,
etc.,
but would love some ideas as to what would make a great "salad greens"
garden.

Thanks very much,
Rachel.
