Summary:
Iowa State University researchers have developed a new seaside alder cultivar, ‘September Sun’.

Development Stage:

Bare root plants are currently available.
Description:
Seaside alder (Alnus maritima) is rare native species in North America.  ISU researchers have developed the first cultivar of seaside alder, ‘September Sun’, that is suitable for use as a nursery crop.  This rapid growing and easy to propagate cultivar is an ornamentally superior genotype and an appealing autumn-blooming landscape shrub.  In addition, this shrub associates with nitrogen-fixing bacteria—unlike almost all other shrub species—which allows the plants to grow on very poor soils and to improve soil quality for other plants.  ‘September Sun’ is also highly tolerant of flooded soils, and helps reduce soil erosion along streams and other riparian areas, making it ideal for landscape restoration projects involving erosion control and wetland remediation.
In various field trials, including one with over 1000 plants and one with a three year growth period, ‘September Sun’ was demonstrated to be the most densely foliated, symmetrical, and rapidly growing seaside alder genotype.

Advantage:
• Fast growing and symmetrical, with attractive foliage and better autumn color than other alders
• Suitable for use in USDA hardiness zones 4a through 8b
• Blooms mid-August through late September
• Able to thrive in wet soil and more drought resistant than other North American alders
• Thrives in nitrogen-poor soil
• Easy to propagate

Application:
Ornamental Landscaping and Environmental Restoration
