The old bulb growers had a saying: bulbs like to mature into a drought. The results you see above are an example of that. Why doesn't this happen in our gardens? When the tulips are maturing in our gardens in June, the soil is full of moisture and the soil temperature is rising. Those are great conditions for soil fungi, but terrible conditions for ripening tulips. Tulips planted in well drained raised beds sometimes persist for years, but tulips planted on the flat rarely do in this garden.
In our climate, if you want to experiment with keeping your tulips going for years, either plant them in raised beds or get them out of the ground before the soil warms up too much.
