Luck O' the Irish

My co-worker's husband works for a company that delivers batches of flowers to a grocery store, who in turn sometimes refuses delivery. They end up with cases of flower bouquets that actually cost them money to throw away. So he brings cases of flowers to the office and we all dive in and grab free flowers. This is one of the flower spikes in the bouquet, I have no idea what this little flower is called. It's interesting though. Many thank you's to the blip monster for shining on me today, as I wasn't going out in the crummy weather today if I could help it.
