Goldenrod is falsely accused of causing fall allergies as it
blooms at the same time as Ragweed, the real culprit. It is also an
easy-to-grow plant that many home gardeners treat as a weed or ignore it for
its commonness.
However, Goldenrod has much to recommend it. It has late-summer
color that lasts for weeks, pollinators love it, and it grows without any care
from this gardener, what more could you want from a back-of-the-border
perennial? It also makes a great cut flower and is an economical filler in
mixed arrangements with more expensive flower selections.
It will self-sow vigorously and that means weeding it
out between pavers and other places where a tall plant cannot be
allowed to remain. It is fairly shallow-rooted though, so it is not a big
problem to pull up after a recent rain. You can also prevent rampant
re-seeding by cutting off the flowerheads after they are past peak, but before
the spill their seeds to the winds.
Most Solidago species originate in the meadows and
open woodlands of North America.
There are better-behaved cultivars of Goldenrod available that are more compact, have showier flowers, and behave less aggressively than the straight species. They include ‘Golden Fleece’, ‘Goldrush’, and ‘Fireworks’.
Goldenrod are not picky about soil types and do not need fertilizing. They do need full sun to do their best flowering. Like many other perennials, the best times to divide or move them are in spring or fall.
