Watching the swallows and swifts this evening while I watered the garden, and waiting for the appearance of the bats overhead as my signal to go inside, I reached down to turn off the well pump and got a whiff of this moonflower – wow! Most of them are planted along the fence surrounding the pond, intermixed with day-blooming morning glories, but a few are in pots up beside the house, where on humid nights their lemony scent drifts in the windows. The smell can be overpowering enough to give me a headache, especially if we also have Angel’s Trumpets blooming. I loved the shape of this flower as it unfurled.
Some cultural info about moonflowers is available in this blog post from 6/8/06.
