Re: TB: CULT: Shade vs. Sun Quandary


Even here in South Aust, where we have very hot summers, we recommend full
sun, for at least half of the day. It doesn't seem to matter if the area is
shaded in winter, it's the baking in the summer sun that is needed to form
the flowering points. I had had iris flower in very light dappled shade, but
no more than that.
