About this cultivar:
Carex oshimensis 'Everillo' is an introduction from Pat Fitzgerald in Kilkenny, Ireland. The solid golden foliage of Carex 'Everillo' makes an incredible elegantly weeping evergreen clump of bright golden foliage. If you put it in a dark in the garden it almost glows! A part-sun location helps hold the brightest colour. A new-ish plant to us but we love it already!

About this genus:
Carex was established as a genus by Carl Linnaeus in his work Species Plantarum in 1753. It is a vast genus of almost 2,000 species of grassy looking plants in the family Cyperaceae, commonly known as sedges. Other members of the Cyperaceae family are also called sedges, however those of genus Carex may be called "true" sedges, and it is the most species-rich genus in the family. The genus is so vast that the study of Carex has its own name: caricology. There are some great stories about this genus, for instance: a mix of dried specimens of Carex have a history of being used as thermal insulation in footwear (such as skaller used by Sami people). During the first human expedition to the South Pole in 1911, mixes were used!
Carex foliage color varies from green, to blue, to gold/orange or variegated. The genus generally forms arching mounds from a few inches to more than 2 feet tall. Carex looks like a grass, is often called a grass, but it is NOT a grass! It is a sedge! In the wild they are often found in wetlands, hence it is unsurprising they prefer moist soil and part shade. However, like most plants in our garden, they grow in most conditions that are not too extreme: they are tough!
Sedges are used mostly as evergreen shade "ornamental grasses" that add dramatic form and blend texturally with most plants. But don't just think of them as "Grasses for shade" they also compliment Liriope and Ophiopogon. Because they like moisture, at Ballyrobert, we often plant them in and around Astilbe, Hosta and Primula where their colourful foliage combines with the flowers of the other plants! (I love red Astilbe with yellow Carex)
