Some seedheads can be a menace

23rd December 2020

Some other seedheads may look decorative, but be a total menace in the garden; if you leave this Solidago canadensis to look ornamental in your borders over the winter, it will spread itself like the invasive weed as which it is classified in some countries. Each stem can produce between 1 and 13 thousand seeds, and once a seeding is established the plant then spreads by its vigorous rhizomes. This plant generally arrives unannounced in your garden and settles in; if you want a goldenrod, try Solidago rugosa 'Fireworks' which is clump-forming and non-invasive.
