I am entitling myself to give more than one answer. The one no one has mentioned is Woodland, or Spanish hyacinth. These are more open than plain hyacinths but fuller than the one-sided squills, non scented, come in pink, blue and white (and the blue is sky blue, not off-white or purple), they bloom a bit later than tulips, and they require very little care. They don't multiply a lot but neither do they disappear.
But I also love daffodils, which win the prize for their poisonous, critter-proof nature and ability to multiply, and which come in so many shades of yellow, white and orange, different sizes and shapes, so I have a mixed bouquet of them throughout April.
I love lilies but have had so much trouble keeping them alive, even with a guard of daffodils, that I am about giving up on them. Tall bearded iris will not bloom for me, I'm giving up on them too, but Siberians are totally hardy and robust and come in many colors.
Here is zone 6 at any rate, gladiolus do NOT have to be dug, they come in nearly all colors, and they make fabulous vase flowers that last for over a week as you remove the spent flowers from the bottom of the stem.
Dahlias have to be dug and may not be the easiest to overwinter, but mine are blooming NOW, in late October--not a lot else is. And they too come in an endless array of styles and colors.
Crocuses, muscari and snowdrops are so small that you have to plant them where you'll see them, but in February no bloom is too small to be appreciated.
One more thing--Brent and Becky's is a bulb specialist with good prices, a large selection and reliability.
