I am not sure if it does make a difference, I am always pretty careful about only using the petals. I imagine it would make the tea a bit bitter.

Ya, it was only those basil trays, I think they were a bit too dry and it is sun scorch. I am not too worried, basil does really well here and it has a couple of weeks to recover. I think I am going against the grain and not planting out this weekend....the temps are dropping to 5 overnight and thats too close to freezing for me!!
