Simpson Stopper Tree

The Simpson Stopper tree has the botanical name Myrcianthes Fragrans. It is an evergreen tree that grows up to 30 feet tall and is sometimes referred to as the twinberry tree. It has a pyramidal shape when young, becomes more rounded with age. The leaves are dark green, measuring 2 to 3 inches long and 1 inch wide. These trees produce red berries in the fall and bloom with snowy white flowers during the spring.

Simpson Stopper trees are easy to grow and adapt to a wide range of soil types and climates. They grow best in USDA zones 8b to 11. Here are some tips to help you grow and care for a thriving Simpson Stopper:

Sunlight needs

The Simpson Stopper tree requires full sun to partial shade. Once established, they are relatively drought-tolerant and grow well in hotter climates. They can also cope with strong winds and do well in coastal areas and in land.


The Simpson Stopper tree prefers well-drained soil but can cope with poor-quality sandy soils. As the trees grow along the coast, they do well in sandy soil, even with high salt content. They can also cope with alkaline soils as they are pretty adaptable.

Watering requirements

Water regularly when young, then once a month once established. These trees are fairly drought tolerant after they’ve reached maturity but do best if they are provided with water, especially during very hot weather conditions.


Fertilize your tree with a balanced fertilizer in spring.


You can prune them as needed to maintain their shape. These trees grow approximately 1 foot each year until they reach maturity. If you want to create a hedge from Simpson Stopper trees, you’ll need to plant young trees approximately 3 to 5 feet apart. Once they have grown to the desired high and spread, you can regularly prune them to keep the shape and form.
