Potted Tulip Care in South
by Desine
(Houston, Texas)
Doug says toss it away or give it to a berserker gardener. Tulips need 14-16 weeks of less than 40F temperatures to get them to bloom again. The odds of you doing that in the Gulf Coast area of Texas are slim to none. :-) Even the beserker gardener will have problems getting it to rebloom.
That's one advantage we northern gardeners have over you southern types. :-)
