Forget-me-nots (Myosotis sylvatica) grow wild in parts of North America, Europe and New Zealand. It grows in zones 3 through 10 and it grows less than a foot tall. The flowers are blue with yellow centres. Plant the forget-me-not flowers in shady, moist areas of your garden. These flowers are often grown as annuals in the garden, but they reseed themselves back. They are actually perennials that come back from the roots.
Dig up the garden area with a garden fork or a tiller to a depth of 6 inches. Amend the soil with 4 to 6 inches of compost. Forget-me-not flowers like soil that is loose and well drained.
Dig holes in the ground with a trowel. The holes should be equal to the container's depth and twice as wide. Space each hole 6 to 12 inches apart.
Remove the forget-me-nots from their containers. If the plants are growing in cell packs, pinch the bottom of one cell to dislodge the rootball. If your forget-me-nots are growing in a pot, turn the pot upside down and tap the rim of the on the side of a table, taking care so you don't hit the plant on the table -- you could injure it. Try to keep the soil around the root ball intact.
Place the rootball into the hole. Backfill the amended soil around the roots and then firm the soil gently in place with your hands. Keep the top of the rootball level with the ground, because the forget-me-not flowers won't grow if they are too deep, as they will rot. If they are planted too shallow, they will dry out and die.
Water the forget-me-nots thoroughly. The top 6 inches of soil should be moist. Forget-me-nots require a moist soil, so check the soil daily. Don't water so hard that the soil washes away from the roots, however, or your plants will die.
