My Serviceberry trees are just begging for me to underplant them with some bulbs for next year's bloom. They've just opened up today.

Anyone in zone 4b or 5a, could you tell me some varieties of bulbs that you have in bloom right now? I'm leaning towards a traditional look...some red tulips along with some daffodils would be great...but any great idea will be very welcome! I need varieties that are coming into bloom now or have been in bloom for 1/2 week, nothing that is finishing, as my trees are just starting. They had swollen buds all last week and today they opened up after a few days of sunshine.

I've posted this in the bulb forum, as well, so hope you don't mind if you see it twice. I'm in Appleton, Wisconsin...that's Northeast Wisconsin.
