Some of the itty bitty bare root siberians that I have gotten from some sources grew very slowly for me because I kept "losing" them. Others from sources like Ensata Gardens grew well right from the start. I have Caesar's Brother and it self sows eagerly. Would you like some seeds? I just let the pods fall over into the row next to the plants, veiled in the foliage - do nothing, and next spring you will see many new plants to transplant. I once collected a mason jar of seeds and grew a row of them.
