Q Katherine • September 1 How long after sowing rattlesnake master will it bloom (first, second, third year?) A Prairie Moon • September 1 Hi Katherine, It can vary depending on growing conditions, but I would say typically three to four years.

Flower heads form from July through September in our region, becoming pyramidal in shape, well branched with green-violet seeds that become purplish brown when mature. Control is difficult. The grass is a highly invasive and tenacious weed that grows in various environments and produces enormous amounts of seed.

Rattlesnake master ultimately reaches about three to four feet tall with a spread of one to two feet.. . . . .364011234276!]0000000000000009783314146238!]
