March Flowers?

I'm still trying to find my green thumb and learn all the names of the plants and flowers in our yard. I planted these gladiolas earlier this year as bulbs transplanted from my mothers yard. Here they are popping up all in a line in my gladiola bed, I can't wait to see them in July with their beautiful pink flowers.


These sweet little grape hyacinth surprised us by lining the outside perimeter of our pool mixed in with the ornamental garlic.


These fast growing soon to be flowers have me wondering. They popped out of the ground about 4 weeks ago and have at least 3 flower stems that have been shy to open. What are they? If you know post a comment because I and dying to know.
