Inflorescence in bloom. Solidago canadensis, known as Canada goldenrod or Canadian goldenrod, is an herbaceous perennial plant of the family Asteraceae. [2] It is native to northeastern and north-central North America [3] and often forms colonies of upright growing plants, with many small yellow flowers in a branching inflorescence held above the foliage.
The soft leaves (dark green on the upper surface, lighter underneath) are alternate, and narrowly oblong or wedge-shaped. The yellow flowers grow widely spaced in racemes at the end of the stem. [6] The pods are thin walled, and widely spaced along the stems, and when ripe are purple to black, containing about 18-20 small brown seeds. [6]
The yellow flowers are in a type of clog shape, containing three asymmetrical petals. These pods rattle when mature and they contain toxic alkaloids. These dehiscent pods are most likely a defense mechanism to assure that animals do not commonly ingest these plants, as doing so is poisonous to a number of them.
An annual plant, yellow rattle grows up to 10–50 centimetres (3.9–19.7 in) tall, with upright stems and opposite, simple leaves. The fruit is a dry capsule, with loose, rattling seeds. The preferred habitat of Rhinanthus minor is dry fields or meadows; it tolerates a wide range of soil types. It flowers in the summer between May and September.
