We're getting ready to order up some bulbs for that 10'x30' bed I just
cleared this summer.

To keep it simple:

Crocus (snow type), blooms earliest.
Crocus (Dutch hybrid type), blooms next.
Daffodil 'Ice Follies,' blooms early, easy to grow.
Daffodil, later variety, your choice.
Wood hyacinth. Blooms latest.

I wouldn't do tulips, since they like sun. Instead, I would extend the
succession by putting in a few azaleas, astilbes, hostas, and Japanese painted
fern. This will give you color throughout the summer.
