The spiderwort (Tradescantia virginiana) has begun blooming in our yard. Most of them look like this, with dark green leaves and dark blue/purple flowers. The flower color is difficult to catch and is actually a bit bluer than how they look here. We have one with chartreuse leaves, which is very pretty but needs a little shade. We also have one with pink flowers. I’ve read that their flowers change color to pink when when exposed to radiation but this one was bred to have pink flowers. If the others all suddenly turn pink, then I’ll worry.

This spiderwort (Tradescantia virginiana) is growing right outside our kitchen door and although it doesn’t have so many flowers at this time of the year, it still manages to put out a few. They are such beautiful little flowers and I can’t imagine not having them in our garden. The color ranges from blue to purple and it’s not always the same in photographs as it is to the eye. It’s possible that some of the color comes from the physical structure of the flower rather than from a pigment but I don’t actually know for sure. Examples of structural colors include those found in peacock feathers, butterfly wings, and the beautiful iridescence of beetle carapaces.
