Thank you Polly. If I have time I will let you know what I find. I am up to my neck just now with jasmine cuttings and 102 deg. heat in the greenhouse. Sometimes I wonder if it is all worth it. I used to be able to work out in this heat, but since they put me on BP and Cholesterol meds I can not take the sun. I am very dark to start with and it is not the burning, it is the heat.
