Description:

Rosa spinosissima L., syn.: Rosa pinpinellifolia L.Scotch Rose, Burnet Rose, DE: Bibernell-Rose, Reichstachelige RoseSlo.: bodiasti ipekDate: June 15. 2006Lat.: 45.92221 Long.: 13.85059Code: Bot_130/2006_DSC0967Habitat: mountain pasture; stony grassland; almost flat terrain; open, warm, sunny place; skeletal, shallow, calcareous ground; elevation 1.030 m (3.380 feet); average precipitations 1.800-2.000 mm/year, average temperature 7-9 deg C, border line between Dinaric and Sub-Mediterranean phytogeographical region. Substratum: soil.Place: Near the top of Mt. Mala Gora, 1.032 m (3.386 feet), aven ridge; Vipavsko, Slovenia EC.Comment: It is easy to recognize Rosa-spinosissima by its small, low to ground habitus, thin branches and dense, strait (never curved!), needle-like 'thorns', better said prickles. The bushes are frequently not much higher than surrounding grass and seldom higher than 0.5 m (1.5 foot). This alone distinguishes it from all other 24 species (Ref.:2) of wild roses growing in Slovenia, which are, when grown up, almost always taller than 0.5 m; most of them are about 1 to 3 m tall. The plant has stolons and hence it frequently grows in large spreading groups. It is not a common wild rose and can be found in warmer parts of the country.Ref.:(1) A.
