Mystery plant

Husband and I are in the process of planting (over a period of time) an area in front of our porch with perennials. It has become a hassle planting annuals every spring and then having to go through the process every year. So, we decided we would only buy perennials from now on. Most of the plants have survived. Some we planted in inappropriate places and will have to either transplant or get new plants -- case in point our Foxgloves which we discovered liked partial shade rather than full sun.

This morning, as I went out to get the mail, I noticed that our "mystery" plant had flowered. I KNOW that husband planted Freesia bulbs which never came up, so we are mystified by what this plant is. So, we are leaving it up to our garden-savvy blogpals to help solve the mystery. I publish for your edification several pictures of this mysterious plant.

The flowers on this plant seem to bloom at night and fold up during the daylight. By the time I looked at the plant around 11 a.m. today, all the blooms were tightly rolled up.

The first one who can correctly identify it will get our unbridled thanks.
