Solidago / Goldenrod
There are about 150 different Goldenrods, most of them native to the prairies, river banks, and mountains of North America. They’ve also spread widely throughout Europe, especially along roadsides and in vacant lots. They’re good for a brief back-of-the-border splash of gold in mid or late summer, though hybrids are now available in short or medium heights and with longer flowering periods. Not as allergy-provoking as is commonly believed.
Newer hybrids especially make excellent, long-lasting cut flowers, especially in mixed arrangements. They dry well, too.
- Typically 5′ or more tall, some varieties are more compact.
- Clumping or spread by rhizomes.
- Best in full sun.
- Hardy in Zones 2-8, depending on the variety.
- Flowers July-October, especially the hybrids.
