Most of the flower heads grow near the top of the main stem. They sometimes form a round clump at the top, but usually they are spread along the upper part of the stem.

One of the commonest common name of Solidago flexicaulis is Zigzag Goldenrod because the stem is usually crooked, zigzagging from leaf to leaf. However, the stem is sometimes virtually straight.

The plant Asteraceae family.

Name

The genus name is said to be first from the Latin adjective solidus that means dense, solid, massive, compact, substantial, and, in a figurative sense, firm, and from the Latin verb agere of first person singular present indicative ago that means something like to do and to make, so that Solidago would refer to the plant's supposed ability to heal. An other but somewhat similar origin would be the latin verb solidare that means to reinforce, to consolidate, and this would refer to the Solidagos as above.

In Latin, flexus means bending, curve. In Greek, καυλοσ (kaulos) means stem; and in Latin caulis has the same meaning. So the epithet refers to the bends along the stem shaft. sep_12_01a.gthmb can't be loaded.
