The term sheep-fescue describes the very heterogeneous, multi-shape sheep-fescue group ( Festuca ovina agg.) (= Collective species ) belonging to the sweet grasses (Poaceae ). It includes closely related clans ( taxa ) which are very similar in shape and which can be differentiated according to the time of blooming, various differences in leaf and flower characteristics, and according to their ecological preferences and their geographical distribution.
distribution
The sheep fescue is distributed differently across Europe , temperate Asia , North Africa and North America , depending on the clan .
description
The types of the group are herbaceous plants of several years . The grasses reach heights of up to 60 centimeters. They are dense clump- shaped growth with bristly to rush-shaped, tightly folded leaves . They are light to dark green, frosted blue-gray or not frosted (wipeable wax layer). The leaf sheaths are in contrast to the collective species Festuca rubra agg. closed at most in the lower third. The ligule are short and inconspicuous. Small round auricles are developed at the transition from the leaf sheath to the leaf blade .
The panicles are up to 12 centimeters long. They are contracted before and after flowering. The panicle branches stand upright. The lowest branch reaches about a third of the length of the panicle. The spikelets are oblong-ovate and tinged with green to purple. They are three to eight flowered. The glumes are narrowly lanceolate and ciliate on the keel. The lemmas are awned or awned. The flowering period extends from April to October, but varies depending on the clan.
The characteristics vary widely within the different clans and there are numerous transitions, so that a determination is not infrequently difficult. In the meantime, good identifying features such as leaf cross-sections and vascular bundles and sclerenchymal cords (cord-like reinforcing tissue) that can be seen in them have been developed.
Small types
The list of species is based on an adaptation by E. Patzke & GH Loos and includes a complex of very similar, in part still undescribed clans.

use
Sheep fescue mostly occurs in extreme locations where more demanding forage grasses no longer thrive and they cannot be displaced by them. Even sheep are reluctant to eat them. The hay is also considered to be inferior. Sheep fescue often hampers the exchange of water and air in the soil with its dense stand and poorly decomposable residues. However, it is recommended as an undergrass for sunny, dry locations on nutrient-poor soils. The type in seed mixtures is also important for stabilizing the ground on dry slopes and embankments.
