Propagating Siberian Bugloss
Be warned that certain kinds are prohibited from being propagated because they are covered by a formal plant patent.
The best way to propagate plants is to division an established clump into healthy pieces in the spring and then replant them.
The best approach to extend the life of Siberian bugloss, which may be short-lived, is to divide them every three to five years. Use a shovel to remove the entire plant from the ground.
Remove any remaining soil to aid in breaking the cluster into more manageable pieces. Remove any unhealthy or weak roots. Use your fingers or a pair of sharp knives to cut healthy roots into parts.
To prevent them from toppling over once they are planted, reduce the size of your leaves to 6 inches or less. Plant each piece exactly at the same level as your previous plant was growing.
When done correctly, this top way of propagation will result in healthier and longer-lasting plants.

Both plants have blue flowers, although the forget-me-not’s are slightly larger. The main difference between the two is that bugloss is an annual, while forget-me-nots are perennials.
