There are about eight pots of this little plant in the upper greenhouses and I have been watching them for months. The flower buds took forever to form and this is the first flower I've seen. This plant is commonly called Virginia Spiderwort. It is supposedly hardy from zone 3a to 9b but I have never seen it grown locally before. I didn't even know the name until a few minutes before taking it's picture. I'm not sure why it's staying in the greenhouse all winter but it may be for propagation reasons.
It does well in full sun or partial shade and requires moist but well drained soil. It typically blooms in June but being in the greenhouse it probably blooms every six months or so. I noticed that one of the tags shows a plant with white flowers and there are supposedly some available in purple as well. The one that I managed to get a picture of is blue. I quite like this plant and I'm excited to see the rest of the blooms open. The feathery stamens give the flower a really delicate feel.
