Steve - I'm surprised that your O&L isn't a blooming machine. This year mine's been blooming constantly all summer. Kinda small, not very lemony (mostly orange) due to the excessive heat, but blooming like mad. Not like a few years ago when I was getting these massive monstrous blooms 4" across. This year, 2-3". Mine's on year.. 4? 3? Either 2008 or 2009 is when I got it.. I'm thinking 2008.
