Planting & Growing
Askola Sea Buckthorn will grow to be about 10 feet tall at maturity, with a spread of 5 feet. It has a low canopy with a typical clearance of 2 feet from the ground, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for 50 years or more. This is a female variety of the species which requires a male selection of the same species growing nearby in order to set fruit.
This shrub should only be grown in full sunlight. It prefers to grow in average to dry locations, and dislikes excessive moisture. It is particular about its soil conditions, with a strong preference for clay, alkaline soils, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America.
