sultry_jasmine_night, I think it has to do more about the environment and the care than I do with the moon phases but again I could be wrong is one checks out how they are grown in the natural habitat?

Sultry_jasmine_night, I have noticed that mine tend to have most of their flushes at the same time as the full moon. Note that I said MOST of their flushes. There are some that come between but for the most part they tend to be just before, during, or just after the full moon. Similarly, most of us have noted that they release their frangrance at dusk or shortly after, which makes me think then that there is a genetic code in them, to help encourage the pollination a.k.a. the survival of the species. My personal thinking is that perhaps it permits the luna moths and other pollinating species to better detect which flowers are best for pollination.

Of course, we are the benefactors of their marvellous ways.

The very first brugs I saw were in a conservatory in Seattle. A worker there told me their brugs bloomed heaviest coinciding with the full moon. With white being a prevalent color, maybe the brugs have "learned" to bloom the heaviest when the bright moonlight best lights up the flowers to attract the moths, along with the evening fragrance mentioned by Jroot.

Thanks for the very interesting observations. I have some night blooming cereus cactus that definitly will bloom around the full moon. I was very curious to find out if brugs did also.
Of course there are some plants like moonflower vine that seem to bloom continuously full moon or not. I guess some brugs may also bloom any old time and then will come in 'flushes' I wonder if they 'typically' do coincide with the full moon (as jroot observed) and for what reasons (bright light as patrick observed), if they do have more intense fragrance at those times? or some other mystery only mother nature knows for now?
I have observed tons of sphinx moths around the brugs in the evening (also noted that mosquitos also visit the flowers- I was told that these were probably the male mosquitos.) They also like my cestrum nocturnum and stephanotis. They basically ignore my moonflowers which are fragrant but much less so than the others.
I think I will start noting in my garden journal when things bloom in correlation with the moon phases.
Thanks

I had my first Brugmansia last year. It had buds, but they
all dropped due the 101 degree temps we had. it put out a second flush and bloomed right at the Full Moon. It was just
amazing. I took tons of pictures of it.

I found this old thread lol! Never did keep that journal....arrrgghh! Gonna have to do now.

interesting thread...I've often wondered about the full moon, too ....if you keep that journal, SJN, please let us know! I'll try to remember to make note, too... have buds right now on three brugs.. we're only at the first quarter in phase of the moon....full moon next Sunday...will be interesting!
