The Story
Plant Bio
Myrica gale, commonly known as sweetgale, is a deciduous, multi-stemmed shrub native to northern bogs, wetlands, and coastal zones across North America and Eurasia. It develops a dense, upright to rounded habit of twiggy branches clothed in oblanceolate, dark green leaves that release a sweet, resinous aroma when crushed.
This species is distinguished by its ability to thrive in saturated, highly acidic, nutrient-poor soils through a symbiotic relationship with nitrogen-fixing Frankia bacteria. In spring, before the foliage emerges, it produces inconspicuous, wind-pollinated catkins—yellowish-brown on male plants and reddish-brown on female plants.

Planting
How to Grow
- Select a site with full sun to partial shade and consistently wet, poorly drained, or boggy soil.
- Amend the planting area with peat moss or organic matter to ensure a highly acidic pH between 4.5 and 6.5.
- Plant container-grown or bare-root specimens at the same depth they were growing in the nursery, watering thoroughly.
- Maintain a thick layer of organic mulch to retain moisture and prevent the soil from ever drying out.
Pro Tip
Plant in permanently wet, acidic organic soil or bog margins, and avoid applying synthetic nitrogen fertilizers which disrupt the plant's natural nitrogen-fixing root nodules.

Common Questions
Sweetgale questions
What zones can Sweetgale grow in?
Sweetgale is hardy in USDA Zones 4–7. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Sweetgale deer resistant?
Not reliably. Deer may browse Sweetgale, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Sweetgale bloom?
Sweetgale typically blooms in spring through spring. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Sweetgale need full sun?
Sweetgale does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
