ORNAMENTAL CROPS AND SEDGES FOR SCREE GARDENS

Abstract

Scree garden is a garden design feature that imitates a mountain landscape. Commonly,
coniferous and deciduous dwarf shrubs and trees, ground-covering plants, ornamental
perennials and cereal crops are planted here. The purpose of this study is to develop a range of
ornamental cereal crops and sedges promising for use in decorative compositions of scree
gardens. For such landscape designs we recommend low-growing cereal crops which grow
naturally in the mountains or in stony soils. They are: fescue grass (Festucagautieri (Hack.) K.
Richt.); blue fescue (Festucaglauca Vill.), such plant varieties as Blue Spreader, Elijah Blue,
Intensive Blue, Compact Blue; Festucapallens Host, variety of Superba; moor grass
(Sesleriaheufleriana Schur). Highly decorative combinations in compositions with other plants
of scree gardens create: purple-leaved variety of cogon grass (Imperata cylindrical (L.) Rauscht)
– Red baron; bright blue – lyme grass (Leymusarenarius (L.) Hochst).; variegated-leaved
varieties of Chinese silvergrass (Miscanthus sinensis Andersson) – Gold Bar, Little Zebra. The
varieties of sedges add various color accents into the composition – the leaves of Buchanan's
sedge (Carex buchananii Berggr) have pale brown colour with a shade of dried grass.; the
leaves of Carex comans Berggr. are copper-chocolate with a pinkish shade, Milk Chocolate
variety; blue leaves of blue sedge (Carex flacca Schreb.). In the narrative drawing of scree
gardens, high grasses can serve as a background, hedge or single planting – Ravenna grass
(Erianthus ravennae (L.) P. Beauv.); Miscanthussinensis, Chinese silvergrass varieties –
Zebrinus, Strictus, Variegatus, Grosse Fontane, Karl Foerster; varieties of shorthear
(Calamagrostis acutiflora (Schrad.) DC. ) – Karl Foerester and Overdam; switchgrass
(Panicumvirgatum L.)
