These flowers only bloomed once in the three years we lived in that house. Funnily enough a similar thing happened when I was a kid growing up in Houston, Tx. We had an apple tree growing next to our pool. We didn’t know it was an apple tree until the last year we were living there. It had never fruited before but then one year green apples just started showing up everywhere. It wasn’t a small tree either, It was huge. Anyway, these flowers were beautiful and I really liked the contrast of the flowers and the hardness of the power pole and streetlight in the background.
