Description:

 

  • Size: Coastal Coprosma can vary in size depending on growing conditions. It typically grows as a shrub, reaching heights of 2-5 meters (6.5-16.5 feet), but can occasionally grow into a small tree reaching up to 10 meters (33 feet).
  • Leaves: The leaves of Coprosma robusta are oval or lance-shaped, glossy, and leathery. They are usually a vibrant green color, though variations in leaf color and variegations can occur within different cultivars.
  • Flowers: The shrub produces small, inconspicuous flowers that are usually greenish-yellow or cream in color. These flowers are often followed by small berries.
  • Berries: The berries of Coprosma robusta are round and typically orange or red, though they can also be yellow or black. They provide a valuable food source for birds.

 

Growing Conditions:

 

  • Climate: Coastal Coprosma is native to New Zealand's coastal regions and is well-adapted to a range of climates. It can tolerate coastal conditions, including wind, salt spray, and sandy soils. It is also suitable for temperate climates with mild to warm summers and cool winters.
  • Sunlight: Coastal Coprosma can thrive in full sun to partial shade. It is adaptable to different light conditions, but it generally prefers a bright location.
  • Soil: It grows well in a variety of well-draining soil types, including sandy or loamy soils. However, it can tolerate a range of soil conditions, including clay, as long as the soil is not waterlogged.
  • Watering: Once established, Coastal Coprosma is relatively drought-tolerant and requires minimal watering. However, it benefits from regular watering during dry periods, particularly when newly planted.
  • Maintenance: This plant is generally low-maintenance. Pruning can be done to maintain its shape or remove any dead or damaged branches. Regular pruning can also promote bushier growth.
