family

Rosaceae

status

Sweet briar (Rosa rubiginosa) is listed as noxious in Class 4 for most of the tablelands and slopes LCAs (Bombala, Cooma-Monaro, Goulburn-Mulwaree, Snowy River, Southern Slopes and Upper Lachlan) and in Wollongong LCA. It is in Class 3 in Queanbeyan LCA.

Description

Deciduous thorny usually few-stemmed shrub with an erect habit. Compound blue-green or bright green leaves with 5-7 rounded leaflets. Large (to 5cm) pink flowers are followed by smooth orange to red "rosehips" which are leathery in texture and full of small seeds.

Preferred habitat

Sweet briar grows in pasture, native grassland and bush, mostly on the tablelands, though it occasionally occurs on the coast.

Dispersal

Birds and foxes feed on the rosehips and spread the seeds.

Look-alikes

Blackberry (also noxious) is a thorny shrub with smaller white flowers and succulent black fruits. Its leaflets radiate like a hand from a common point of attachment, while sweet briar leaflets are arranged in opposite pairs. Other types of roses may occasionally persist around old house sites or in cemeteries, sometimes reverting to wild rose types from the rootstock.

There are some native shrubs with spines, but their spines are smaller and straight, not the curved thorns of sweet briar and blackberry (see the blackberry page for photos of these).

Control

Spray with a woody weed specific herbicide. Goats provide very good control but need good fencing and can be rough on any native vegetation in the paddock. Plants can be dug out, but will resprout from the roots if the whole root system is not removed.
