Beautiful plant, Karma!
There are probably cabbage worms, army worms, who knows what munching on my Brug leaves. They are always full of holes. I never pay any attention to the leaves.
I haven't been able to see any pattern to the blooming in regard to the weather here. We did have the stretch a little over a week of over 100 days, but otherwise, it's been the normal temps of 90-98 every day. The thing that has been different this summer is the rain. Since June, I don't think there has been a stretch longer than 10 days without rain, and that seems to have made a difference in getting a lot more blooms a lot earlier in the year.
I won't waste time putting any more of them in pots in a lot more sun, that has been a bust even though the soil has never run dry. If heat is a factor, it's only affected my potted plants. Those roots get a LOT hotter with the sun baking the pots most of the day.
It's too humid here to think about misting anything, but I never mist anything anyway except to spritz an air plant when it's inside for winter.
I can only speak about B. suaveolens, the only kind I have.
