Goldenrod, the Solidago species

This is:

A potpourri (below) of goldenrod/Solidago information as a supplement to other articles.

A plant-based page rather than our usual topic-based page. It's a pivot point, one list of links to ours and others' articles that involve goldenrod species.

We're just introducing this set of perennial info pages. This page is in process but Aster's page is complete. We hope you'll take a look there and comment. Let us know if the format was useful, share your suggestions, tell us we shouldn't have this page at all... anything helps.

There are dozens of garden-worthy goldenrods but they are not popular, perhaps because of the misconception that they cause allergic reaction. Goldenrod, with pollen so heavy it must be carried by bees, does not cause allergic attack and should never have been grouped with the grasses and other plants whose pollen is airborne and irritating to hayfever sufferers. (Perhaps goldenrods have a cartoonist to blame for being passed over by gardeners. See our links, at the end of this page.)

Below: If you suffer from hay fever, watch the bees to help you select flowers that will not irritate your nasal passages. Goldenrod pollen is too heavy to float -- to reach other goldenrods and create seed, it must be carried by bees. A person would have to stick the flower into his or her nose, to inhale the pollen. Even then, it may not trigger anything more than a nose-clearing sneeze.

All goldenrods were once in the genus Solidago but that big group was recently split. Many former Solidago species are now classified as Euthamia or Oligoneuron. A few became Chrysoma or Gutierrezia. We'll try to keep them straight by their new names but we're glad the botanical community will list both names in reference books for ten years or so. It may take us that long to break old memories and replace them with the new names.

Below: Goldenrods carry a late summer garden, many blooming into the cool days and low angle light of early fall when yellow flowers are especially beautiful. (On the right, accompanied by October Daphne sedum and the re-bloom of lanceleaf Coreopsis (C. lanceolata).
