The majority of Tulips bulbs we buy are not perennial. Tulips have been bred to produce strong blooms, and to flower in our climate, which is not the natural climate for Tulips.
Wild tulip are found in Central Asia and Caucasus region, also Afganistan, Jordon and Kurdistan. These are small Tulips with unimpressive flowers and, along with Tulipa schrenckii, which inhabit the Eurasian steppe, are the origin of the complex flowers we grow today. The natural climate is very cold winters, and hot dry summers, not akin to the UK.
Most Tulips bulbs are sold as bedding, and with the cut flower market in mind, and are best treated as annuals. Unless they are specifically one of the perennial varieties, it is not worth the time and trouble of trying to coax them into weedy flowers for next year. Dig them up and compost.
There are a few types of Tulips which may flower again the next year. If you want a more permanent display , check out any of the varieties listed below which are billed as perennial Tulips.
