We got up this morning to discover an overwhelming, sweet aroma in the main greenhouse. Lynn-Marie had checked it out the night before with the flashlight but hadn't seen it. But this morning, there it was. One of our Epiphyllum oxypetalum plants was blooming, the first such bloom of the season. I'm sure there will be more to come, but for now, what a way to begin the day.
There's a very nice time-lapse video of one of these flowers opening here.
