I was mailed a lot of seeds this tropical annual some call 'Jamaican Cranberry' and since there is ample evidence that the tea consumed daily can lower blood pressure I will be growing some in Water Wise Container Gardens made from recycling bins in the all-new south bed. It's been years since I grew it. Both the leaves and the calyxes (source of color and tart taste of 'Red Zinger' tea) contain many beneficial compounds. John
