"Exploring the Diverse World of Polygonaceae: From Dew-Covered Dragonflies to Vibrant Rhododendrons" A Scarce Chaser dragonfly (Libellula fulva) delicately adorned with dew, finds solace on a bed of common sorrel (Rumex acetosa) at Lower Tamar Lakes in Cornwall, UK during the enchanting month of May. The autumnal hues embrace a Hybrid Poplar tree plantation (Populus sp. ) at Boardman Tree Farm near Irrigon, creating a captivating tapestry of colors that celebrate the beauty of this Polygonaceae family member. Amidst the serene waters of Westhay SWT reserve in Somerset Levels, an Amphibious Bistort (Polygonum amphibium) blooms gracefully, adding splashes of pink and white to the tranquil lake scenery. Alexanders rhubarb (Rheum alexandrae) and Dwarf purple rhododendron (Rhododendron) intertwine their vibrant foliage, showcasing nature's artistic collaboration between two remarkable members of Polygonaceae. Witnessing a delightful encounter in Devon, England, we find a Harvest mouse (Micromys minutus) relishing its meal on Sorrel leaves (Rumex acetosa), highlighting the vital role this plant plays within the ecosystem. An Alpine Dock plant (Rumex alpinus), depicted through a vivid color lithograph, showcases its unique characteristics and resilience as it thrives amidst challenging mountainous environments. Mountain Sorrel's delicate presence is captured beautifully in another color lithograph; Oxyria digyna stands tall against harsh conditions while adding elegance to high-altitude landscapes. French Sorrel's distinctive heart-shaped leaves are brought to life through yet another stunning color lithograph; Rumex scutatus adds charm and flavor to culinary delights around the world.
