This plant has a low, mounded appearance and makes an excellent groundcover. Feature Mon Amie Blue in beds, borders, or containers. This plant is a vigorous grower and can quickly overtake an area, so featuring it in containers keeps it under control. This plant grows as a perennial in zones 3 through 8.
Mon Amie Blue Forget-Me-Not Care
Grow the Forget-Me-Not in full sun or partial shade, although this plant prefers morning sun and afternoon shade in warmer climates. Plant it in rich, moist, and well-drained soil. This beauty has high water needs, so keep the soil consistently moist, but do not leave it in standing water. Top-dress the soil with organic compost or mulch or apply a balanced fertilizer in the spring.
