Morella pensylvanica (Northern Bayberry)

A genuine coastal workhorse, northern bayberry fixes its own nitrogen via root-associated bacteria - enriching poor, sandy dune soils for the species that follow it - while serving as the confirmed larval host for the striking Columbia Silkmoth.

Species Overview

Morella pensylvanica, also known as northern bayberry, is a semi-evergreen shrub found along coastal areas from Canada to Virginia (and barely into North Carolina), highly salt-tolerant and thriving in sandy or rocky soils. It grows 5 to 10 feet tall, with aromatic leaves and waxy gray berries historically used to make bayberry candles.

Application

• Coastal dune and erosion control plantings - highly salt-spray tolerant
• Nutrient-poor sandy soil restoration - nitrogen-fixing pioneer species
• Natural hedges and shrub borders
• Larval host habitat for the Columbia Silkmoth

Planting Guidance

• Dioecious - both male and female plants are needed for berry production. Nitrogen-fixing via root-associated Frankia bacteria, making it a beneficial pioneer species on poor sandy soils.
