Answer: Going by your description, it is possible that you have some of the excellent, smaller growing, early flowering tulips that tend to perennialize. (The Greigii group, for instance, has foliage with markings like that.) These would behave as you decribed, dying back in late spring and reappearing a year later. If the original planting had become crowded, or if you moved them prior to bloom time, the bulbs could have been too smallor too shocked to bloom. With a year or two of care, however, you may find that they rebuild their strength and do bloom again.
