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.

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.
Spiderwort (Tradescantia virginiana) is one of my favorite perennials. It’s easy to grow, it does well in sun or shade, it can take fairly dry conditions, and it blooms for a nice, long while. We have one with leaves that are very pale green, almost yellow. We have one with flowers that are much more pink and some that are nearly pure, deep blue. Each bloom lasts for a day only but there are a lot of them, following one after the other.
From the Missouri Botanical Garden page:
Genus name honors John Tradescant (1570-1638) and his son John Tradescant (1608-1662), botanists and successive gardeners to Charles I of England.
Specific epithet means of Virginia.
When the stems of spiderworts are cut, a viscous stem secretion is released which becomes threadlike and silky upon hardening (like a spider’s web), hence the common name.
This is the first bloom on our Tradescantia (spiderwort) out front in the shade garden. This one is lighter purple than most but still quite pretty. I especially like the deep purple stamen hairs and the yellow anthers. Apparently, when the stamen hairs are exposed to ionizing radiation they turn pink. Looks like were safe, for now.
