I thought this was very cool as well. The gardener guy referred to this as some 'whirling something or another'
Maybe he didn't really say something or another, but I've forgotten.
We went looking around, but we weren't able to find similar plants down here at Lowe's and Home Depot.
When we told the master gardener that we had some four o'clocks that we started from seed, and that it had been a few seasons, she responded with "And how is it working for you?"
I guess there are others that aren't happy with four o'clocks.
Now that we got about an inch of rain today, the four o'clocks are looking perkier.
We don't quite have the irrigation system for supporting this type of floreing bush for very long.
Most of our plants are drought tolerant.
