Hi, we moved in to an older home built in 1950, for the last 3 years this flower comes up and I would like to know what it is, it looks like some kind of lily but I'm not sure. Every year it starts out looking like a large clump of thick bladed grass, then that all dies back to the ground in late July, early August. The plant looks like it died, then about a week later it shoots up four to five strong spikes with clusters of buds just at the top. It is pink with some blue tones to it and smells like Lilacs. Any Ideas as to what it is? Michele
