Oh wow, just looked. Those are some serious cash for annuals but really make a big impact. I'm a higher zone but we never get the summer temps you have and the nights are mostly cooler. I think we only get a few weeks in the 60's and much more rain.
Maybe, I may find them around here. I think they have them here in the house plant sections.
Really great combos! I just love all foliage combos as they always look good.
