That's not uncommon and some brugs seem more susceptable then others. I think it has to do with temps. I had a Trop. Sunrise send out a flush of all split blooms last season but they do return to normal.
Karyn

wow that is the first time I see a bloom like that. Does it still open more and is just split?
Beth what Brug is it?

Hope your next blooms are normal again.

Lucy

My Jamaican Yellow did that last year... It had a few blooms split like yours and the rest were normal all in the same flush. Then I didn't see the splitting on any other flushes afterwards. Everyone here said that it was common on JY. I've never seen it on any of my others. What brug is yours?

I sure hope you're right, Karyn and wildflower - that they'll return to normal. It's happening on the Jamaican yellow, Lucy, (the one pictured) and another NOID yellow. the blooms just splits..doesn't seem to open - there's no 'fabric' to open!! Have creamsicle blooming right now, too, and it's perfect!
I'm in Florida; the summer has been crazy - hot, drought, floods, tropical storms...oh, and did I mention the doggone spider mites??? These ten plants have all been in pots until this weekend (I don't think that the transfer from the pot to the ground caused this...it's just too soon.) Up until a week ago, I was dragging a hose to them almost every day and then we suddenly have had a deluge of rains, again. They've had everything inconsistent. I gave them miloganite on Saturday when we planted them...wondering if I should have withheld the fertilizer! ...and today, it's rained again.
