rosemary - colours question
I'm sorry if this is the wrong forum for my question but since rosemary might wind up in potage I thought you'd let me ask here.
I have the regular, common or garden variety of rosemary and it's doing quite well despite the fact that it gets little care or attention. My wife has come home from her job with a sprig of rosemary from the garden there and the flower is bluer.
Before I put mine out and start again, can anyone tell me whether, if I improve the nutriments etc. and actually water it, the colours might deepen?
Any advice gratefully received!
