Apparently the yellow blooming crocuses tend to flower first—but only by a few days to a week. That’s the suggestion of this study of bulbs for Kentucky gardeners: http://www.uky.edu/hort/sites/www.uky.edu.hort/files/documents/5204springbulbs.pdf see the chart on page 3, and not the March dates at the top. Presumably those dates would vary in other gardening zones.

We hope this help…
