As an autumn-cut flower, Golden Rod is not to be despised, although it is often referred to slightingly. Growing well in ordinary soil and in full sun or partial shade, the plants do not require any spedalsituation. It is wise to thin out growths and so obtain better spikes of.
Unrestricted growth results in crowded inner, and certainly when the older woody parts die it is made easy for disease to enter and spread from such places. Perhaps the ideal way to maintain a first-class stock is to place some plants in the cold frame in the autumn, when flowering is over, and make small divisions of one or two crowns each in the early spring. These are planted out at 18-24 in. apart, to give room for good blooms for to develop.
Flowers are available from the end of July until October and good varieties are: S. canadensis, 5 ft; S. shortii, pyramid-shaped spikes of 4 ft or more. Recently, several new kinds have been introduced, which generally are considerably shorter than the older varieties.
These include `Goldstral’, bright yellow, 4 ft; ‘Golden Gates’, ‘Golden Falls’ and `Lemore’, all 2 ft. S. missouriensis was once widely known under the name ofhybridus luteus, growing just over 2 ft; it has distinct panicles of star-like yellow flowers. ‘Golden ’ is also of value as a dried flower.
