Description

Heartleaf Hornbeam (Carpinus cordata) is a beautiful deciduous tree native to eastern Asia, admired for its dense canopy, attractive serrated foliage, and smooth gray bark. This hardy ornamental tree develops an elegant rounded form, making it an excellent choice for parks, large landscapes, woodland gardens, and street plantings. During autumn, the rich green leaves transform into shades of golden yellow, providing excellent seasonal color. Heartleaf Hornbeam is long-lived, adaptable, and relatively low maintenance once established.

Germination Instructions

Heartleaf Hornbeam seeds require a warm and cold stratification period to break dormancy and achieve successful germination.

  1. Soak seeds in room-temperature water for 24 hours before stratification.
  2. Place seeds in a moist growing medium such as peat moss, vermiculite, or sand.
  3. Warm stratify for 30–60 days at approximately 68–75°F (20–24°C).
  4. Follow with 60–120 days of cold moist stratification at 34–41°F (1–5°C).
  5. After stratification, sow seeds about ¼ inch deep in a well-draining seed-starting mix.
  6. Keep the soil consistently moist but not saturated and maintain temperatures around 65–75°F.
  7. Germination typically occurs several weeks after the cold stratification period has ended.
