Landscape Attributes

This tree will require occasional maintenance and upkeep. When pruning is necessary, it is recommended to only trim back the new growth of the current season, other than to remove any dieback. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

  • Insects
  • Disease

Sea Urchin White Pine (tree form) is recommended for the following landscape applications;

  • Mass Planting
  • Hedges/Screening
  • Rock/Alpine Gardens
  • General Garden Use

Planting & Growing

Sea Urchin White Pine (tree form) will grow to be about 4 feet tall at maturity, with a spread of 24 inches. It tends to be a little leggy, with a typical clearance of 2 feet from the ground. It grows at a slow rate, and under ideal conditions can be expected to live for 50 years or more.

This tree should only be grown in full sunlight. It is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. It is not particular as to soil type, but has a definite preference for acidic soils, and is subject to chlorosis (yellowing) of the leaves in alkaline soils. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided, and will benefit from being planted in a relatively sheltered location. This is a selection of a native North American species.
