Dear Jim, They are dormant during the summer. Tulips won't rebloom next year without a long chill time in the 30s, so if you plant them in the ground it will be too warm. Could try potting them and putting the pots out in the cold next year, but maybe next year we won't even get any frost. I worked for a greenhouse here in apopka and we would force bulbs, after potting they were put in the giant cooler for a couple months to sprout in the cold.
Vernalization: Subjection of seeds or seedlings to low temperature in order to hasten plant development and flowering.
