Members of the genus Cynoglossum are long flowering biennials that are normally grown as annuals by gardeners.
They are weedy in nature and have forget me not flowers of blue, purple or white from the summer through to the end of autumn.

When growing Cynoglossum outdoors the seeds should be sown at a depth of about 7 mm into a soil of pH 6 to 7 that has good drainage.
Chinese forget-me-not prefers to grow in an area of the garden that is either sunny or partially shaded.
Forget-me-not's can be sown either in the autumn or a couple of weeks before the last frost of summer.
When growing Chinese forget-me-not's as seedlings indoor for later transplanting then they should be prepared about 7 or 8 weeks before they are due to be planted outdoors at the end of spring.
Once ready the Cynoglossum seedlings should be planted out with a space of about 25 to 30 cm.
At the end of the growing season the flowers of Chinese forget-me-not should be dead headed to prevent the plant from setting seed and taking over the garden.
