Grows with ease in fall, and can be sown in spring if care is taken to protect young plants from temperatures of 50F or below, which may cause plants to bolt. Grows best at 60-65F. This packet sows up to 43 feet.

Persistent temperatures of 50F or below while plants are young can cause bolting (premature flowering), cover as necessary.
