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.

Entretien

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.

Arrosage
Keep the soil consistently moist but never waterlogged during the active growing season.
Engrais
Apply a light layer of compost or organic mulch in the fall to provide nutrients for the coming spring.
Taille
Simply remove the yellowed, dying foliage once the plant goes dormant in late spring or early summer.
Rempotage
These prefer to stay in the ground, but you can divide clumps every few years if they become too crowded.

La cultiver

Multiplication
division, seed
Quand planter
fall, early spring
Hivernage
No special care is needed as the plant is fully dormant underground during winter.
En pot
It is not well suited for containers because it requires specific woodland soil conditions and goes dormant.

Division

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

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

Bonnes associations

  • White Trillium — They share similar woodland habitat requirements.
  • Christmas fern — Ferns fill the space left behind when the bluebells go dormant.

Espèces similaires

  • Lungwort — It shares similar blue flowers and woodland preferences.
