Virginia bluebells.

Mertensia virginica

Pronounced mer-TEN-see-uh ver-JIN-ih-kuh

Also known as Lungwort oysterleaf, Roanoke bells, Roanoke-bells, Virginia bluebell, Virginia bluebells, Virginia cowslip, Virginia lungwort, Virginia-bluebells

Virginia bluebells are lovely spring ephemerals that bring a splash of color to woodland gardens. They bloom with nodding clusters of pink buds that open into bell shaped blue flowers. Once the seeds set, the foliage fades away until next spring.

Care

Plant these in a spot with rich, moist soil that stays cool throughout the spring. Keep an eye out for slugs or snails that might snack on the tender new leaves. Since they go dormant, mark where you planted them so you don't accidentally dig them up later.

Watering: Keep the soil consistently moist but never waterlogged during the active growing season.
Feeding: Apply a light layer of compost or organic mulch in the fall to provide nutrients for the coming spring.
Pruning: Simply remove the yellowed, dying foliage once the plant goes dormant in late spring or early summer.
Repotting: These prefer to stay in the ground, but you can divide clumps every few years if they become too crowded.
Soil: Rich, moist, well draining soil
Soil pH: 6.0 to 7.0
Temperature: -30 to 30°C

Growing it

Propagation: division, seed
When to plant: fall, early spring
Overwintering: No special care is needed as the plant is fully dormant underground during winter.
In containers: It is not well suited for containers because it requires specific woodland soil conditions and goes dormant.

Division

1. Wait until the plant is fully dormant in summer.
2. Carefully dig up the root clump.
3. Gently pull the roots apart.
4. Replant immediately in a shady spot.

Pair with late emerging perennials to hide the empty space left when the bluebells go dormant.

Grows well with

Trillium · They share similar woodland habitat requirements.
Ferns · Ferns fill the space left behind when the bluebells go dormant.

Similar species

Lungwort · It shares similar blue flowers and woodland preferences.
