My sunflowers are annoying, the never face the sun/south, in my north facing garden, they point N/E. What's that all about? Prevailing wind comea from S/W, could it be that?
I have tried perennial sunflowers in the ground this year, but it's hopeless with so many slugs. They've barely made one foot tall. Lemon Queen never made it back at all.
