Forgive my total lack of knowledge, this is my first year with tulips, first time ever I have gotten bulbs to grow in the ground and not in a container, and my first ever blooms (I can't get potted narcissus to bloom for the life of me)!

My question is, does each bulb only give one flower a year? I know I read about some that I think said would have multiple blooms at one time, but mine appear to be singles, so does that mean I only get the one? I wish I could find my package with the specific one I have on it, but I can't. All I know is it's from Lowes and here is a pic of my first bloom:

Secondary question: my first bloom opened yesterday morning and then we had record highs in the 90s and it looks so sad now. Did it kill it? I have several more open today with similar highs expected again, is there something I can do to protect them?
