this is over a week and some time. The front is paradoxa. Right is pallida. The 2 tall white blooms to the left of the paradoxa is 'hula dancer'. Kinda interesting to see how they bend and straighten as they grow. You can also see the leaves relax a bit in the hot sun and the pop back up at night.
There's music!
