Seed ripensearly November

Drought tolerant plant with bright yellow clustered flower heads. It's a bit of a thug, growing tall and big around, pushing its roots about (but not too agressively), and seeding here and there too. But the insects love it, and it's a big bold statement in the late-summer garden, so we gladly reserve space for it.
I used to list this as Solidago missouriensis, but according to a botanist to whom I sent a plant, it is in fact canadensis; according to her: "The key to identifying this plant from its close relatives is to look for hairs on the stem and in the inflorescence. Solidago missouriensis has a hairless stem and is also hairless in the inflorescence. Solidago gigantea also has a hairless stem but is hairy in the inflorescence and Solidago canadensis is hairy throughout. The plant I received has a hairy stem". I never question the opinions of those who actually study these plants, so I adjusted this page accordingly.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.
