Check out its cousin, scarlet spiderling!
This one was a bit tricky, because the flowers normally have a pinkish tinge. This one was a very bright white. Plus, it has a long growing season here in the Keys, so I most often find the bright red berries forming simultaneously with new flowers. I’ll head back over to double check the fruit in a few days. This species is more common than its close relative, Guinea hen weed. Find more info here.
Currently, many sources still list this under its older synonym Cordia globosa.
