It had 2 blooms a few weeks ago. And then, to my surprise, along comes another bud. I was fairly certain that I knew which night it would open. And every 15 - 20 minutes I'd go check on it. Well I was right except it opened during one of those 15-20 minute wait times while my back was turned! But it was lovely nevertheless. Have a look.
Next surprise was that the bloom was still open at 9:30 a.m. instead of the usual 7 - 7:30 a.m.
