Fall bulbs to plant for spring flowers in zone 5b

Springtime flowers are a beautiful way to be reminded of the upcoming warm seasons. Depending on the kinds of flowers planted, you can see blooms begin to form just as snow begins to melt, and with planning, you can stagger bloom times throughout the spring and early summer. Daffodils and tulips are easily thought of as bulbs that break through the soil in spring, but looking a little bit more in depth, there are many kinds of flowers that can be planted in autumn for a springtime show. For a technicolor display throughout the beginning of next year, try planting some of the bulbs listed below, as recommended by the University of Illinois Extension:
