The goldenrod (Solidago), a member of the daisy family, is mainly native to North America, but there are also species native to Europe and Asia. The bright yellow flowering perennials are a popular garden perennial due to the eye-catching flower color and their long flowering period.
The goldenrod shows its beautiful yellow flowers from July
Goldenrue blooms late in the year
Goldenrods usually bloom between July and September, often well into October. The Canadian goldenrod (Solidago canadensis) is one of the so-called short-day plants, whose flowering period only begins in late summer - when the days are getting shorter and the nights longer.
Recommended ornamental varieties
In addition to the wild forms of goldenrod native to the world, there are numerous hybrids that have been bred specifically for cultivation in gardens. Most of these also come from the USA. These also have the advantage of hardly ever multiplying via root suckers. The table below gives you a good overview of some recommended varieties.

tips
Since all goldenrods reproduce very quickly by self-seeding, you should cut back the plants immediately after flowering to prevent seed formation.
