Creeping Soft Grass
Habitus Scientific classification Kingdom: Plantae (unranked): Angiosperms (unranked): Monocots (unranked): Commelinids Order: Poales Family: Poaceae Genus: Holcus Species: H. mollis Binomial name Holcus mollis
Holcus mollis is a rhizomatous perennial grass found in woods and hedgerows, growing to 50 cm tall. It has rhizomes that occur around 5 cm deep in soil or sometimes deeper. Rhizome growth occurs in the period May to November but is fastest from mid-June to mid-July. The rhizomes have many dormant buds that do not develop unless the rhizomes are disturbed and then fresh aerial shoots may arise from the broken fragments. It flowers from June to July.
Holcus mollis is favoured by conditions in woodland clearings and at the early stages of coppicing. Growth and flowering are restricted as the tree canopy develops. It is often a relict of former woodland vegetation, surviving in open grassland and grassy heaths after woodland clearance despite being a shade lover. It is found mostly on moist, freely-drained acid soils, normally light to medium texture and high in organic matter; it is absent from areas of calcareous or base rich soil, and often grows with bracken.
Status as a weed
In a survey of weeds in conventional cereals in central southern England in 1982, it was found in 1% of winter barley but not at all in winter wheat or spring barley.
Each small piece of rhizome is capable of developing into a new plant. Research shows that within 6 - 8 inches of the surface, a square foot of rhizome infested soil may contain up to 110 feet (34 m) of rhizome, the weight of roots and rhizomes being estimated at 7.5 tons per acre.
Varieties and hybridisation
A pentaploid variant of Creeping Soft Grass is common in Britain, it is sterile but spreads vegetatively. Var. H. mollis variegatus has striped green and white leaves; it is sometimes cultivated.
