Several plants close together by a stream.

Flowers in a spike near top of 60cm stem, sparsely populated by narrow lanceolate leaves. from afar could be mistaken for Agrimony, but the flowers are a much deeper yellow.

This specimen has short alternate flowering side-branches set about 60° upwards, with short linear leaves coming from each juncture. A golden rod.

Alternate side banches alternate with curled-over linear leaves. Flowers are bright yellow, with between 6 and 10 long ray florets that are elliptical in outline.

Yellow flowers not unlike those of Ragworts.

The side branches have even shorter, narrower linear leaves peeling away and back from it.

The sepal teeth are long and thin, and of various lengths.

The flowers are close to the main stem in short branches off the main sten.

Flowers are much larger than those of Canadian Goldenrod, and the jizz of the plant is quite unlike that of same.

Flowers could easily be mistaken for Oxford Ragwort. Disc florets have orange stripes and are far from numerous.

Lower leaves slightly broader than upper stem leaves.


31st July 2007, Gait Barrows, Silverdale, Lancs. Photo: © RWD
Stem leaves narrower nearer the top.

Teeth on leaves either absent, or very slightly toothed.

Stem hairy and striated in red and green stripes.


Some similarities to : Oxford Ragwort and Common Ragwort, but leaves are very different.

With 5 yellow petals it has a slight resemblance to:

  • Agrimony from afar, but flowers are larger, held further away from the top of the stalk, and of a brighter golden yellow.
  • Some St. John's Worts, such as Hairy St. John's Wort (apart from the hairs).
Unexpectedly, the flowering season is a month earlier in the hills, starting from June rather than July.

Habitat: likes growing in wooded, rocky or grassy places.

Goldenrod contains saponins derived from Polygallic Acid such as Virgaurea saponins I, II and III, Virgaureoside A and Leicarposide. Virgaureasaponin 3 is a new 3,28-bidesmosidic triterpene glycoside, specifically 3-O-β-D-Glucopyranosyl - (1→3)-β-D-Glucopyranosyl Polygalacic Acid. Leicarposide, a phenolic glycoside, is hydrolyzed to Salicylic Acid in the gut and because of this displays anti-inflammatory and analgesic activity. The diuretic properties of Goldenrod are said to be due to flavonoids.

It also contains some plant-defensive chemicals, the cis-Clerodane diterpenes, such as Elongatolide C & E, to guard against external pests. Also Solidagolactones I-VII. Also some acetylenic compounds.

European Goldenrod contains several flavonoids (Quercetin 1.5% and Kaempferol plus their glucosides: Astragalin and Rutoside respectively. Also triterpene saponins of the Oleane type (2%) and the bisdesmosidic phenol glucoside Leiocarposide and Virgaureoside.

The small amount of essential oil obtained from Goldenrod contains Cadinene, Pinene, Myrcene, Limonene, Sabinene and Germacrene D.

Several phenolic acids are present such as Caffeic Acid, Chlorogenic Acid, Ferulic Acid, Sinapic Acid (Aka Sinapinic Acid) and Vanillic Acid.
