Fall Planting Bulbs

I am thinking about adding a few bulbs to the babkyard this Fall. It is still too early to do the planting but it is not too early to make a plan.

The bulbs that I am considering are ones that, of course will bloom in Spring, for example:

Daffodil

Crocus

Hyacinth

Snowdrops

Tulips                  

Daffodils are my wife’s favourite so they are a must and I love tulips so those too will be added. Now I just need to decide which ones to plant and where to plant them, I am thinking that a naturlaized look is what I am seeking.
