Solidago canadensis is a PERENNIAL growing to 1.8 m (6ft) by 1 m (3ft 3in) at a medium rate.It is hardy to zone (UK) 3. It is in flower from August to October, and the seeds ripen from September to October. The species is hermaphrodite (has both male and female organs) and is pollinated by Insects. The plant is self-fertile.It is noted for attracting wildlife.Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.
Water goldenrod moderately when the plant is young and establishing itself. But, once mature and properly located in the landscape, native plants such as goldenrod need very little care. The plant should thrive alongside other drought-resistant plants.
Goldenrod craves full sun and makes its best showing late summer. The plant will tolerate a bit of shade, but may not perform as well under such conditions.
Fertilizing goldenrod is not necessary, as the plant grows in the worst soil conditions imaginable. However, if you wish to give your plants a boost or increase their height, fertilize them with organic compost in spring.
Most types of goldenrod are native to North America, where they grow as wildflowers in pastures and along roadsides. This gives you a good idea of how tough this plant really is, since the soil along roadsides is often poor. In its native region, goldenrod requires little care. The only real requirement for this wildflower is proper drainage, although it's even been known to tolerate clay-like soil.2
Goldenrod can thrive in almost any climate that has ample sun. A slight variance in air humidity and or dryness will not affect its growing conditions. Goldenrod craves mid to late-summer heat and performs best in temperatures ranging from 80 to 86 degrees Fahrenheit.2
Weak potential for sensitization. Irrigation therapy is contraindicated in cases of oedema due to renal or heart disease. Care needed with chronic kidney disease
