This short heath species blooms from June until October in upland Wales. We took this photograph on the flat moorland top of Llanllwni Mountain, to south-east of the Teifi Valley.
The delicate flowers of cross-leaved heath are paler than those of bell heather, but otherwise the flowers are similar in size and shape; however, whereas bell heather prefers dry soil, cross-leaved heath thrives in damp, peat-bog areas. A distinguishing feature is the leaf arrangement of this plant: the leaves are set in whorls of four.
