Propagation Notes Compass Plant
Alternative Method - Fall sow in an outdoor cold frame. It is best to cover them well with potting soil, making it more difficult to small mammals like mice to discover them Slow to mature - Silphium laciniatum was started from seed in February 2016, we didn't expect flowers the first season but were surprised when not one of our Compass Plants bloomed in 2017.
Hopefully, they will get down to business in 2018 - They Did!
