Secretary of War brings back the flower of peace

The association of poinsettias with Christmas is said to have begun over 500 years ago. The plant has been growing in dry tropical forests, along the Pacific coast from Mexico to Guatemala, for even longer than that.

The cannabis aphid is a pest aphid found on the leaves and stems of cannabis. Aphids have "piercing-sucking" mouthparts to feed on plant fluids. When aphids occur in high numbers, their feeding can stress plants and cause wilting, yellowing and other damage. Cannabis aphids are also potential vectors of plant pathogens.
