Forget-me-nots are dainty, low-growing plants that form a cloud of blue color. They create a phenomenal show when used as companion plants for tulips, which bloom at the same time in late spring. A different flower, called Chinese forget me not (Cynoglossum amabile), is a cool-season annual that produces upright stems topped by clusters of blue flowers in summer. It is easy to grow and does not require cold exposure to trigger flowering.


Allow some plants to stay in the garden until they develop mature seeds. With encouragement, forget-me-nots will reseed themselves for a season or two. Keep a close eye on strains that are strong reseeders. In some areas forget-me-nots are considered weedy, including parts of the Pacific Northwest in the US.


Plants must be exposed to a period of cold before they will bloom well. In cold climates, start plants indoors in late winter and set them out in early spring so they experience several weeks of cold weather.
