Simpson Stopper (Myrcianthes fragrans)
Common Names: Simpson Stopper, Twinberry, Florida Stopper.
Best Growing Environment: Simpson Stopper is a versatile and hardy native of Florida and the tropical Americas. It thrives in a variety of soils, from well-draining sandy soils to those that are more loamy. The plant is also salt-tolerant, making it an excellent choice for coastal landscapes.
Average Height: Typically, the Simpson Stopper grows to a height of 5-20 feet, depending on its environment and care. Given the right conditions, it can occasionally reach up to 30 feet.
Growth Rate: This shrub to small tree has a moderate growth rate. Its compact growth habit requires minimal pruning, especially when it's allowed to grow naturally.
Sun Requirements: Simpson Stopper is adaptive and can thrive in full sun to partial shade. However, for best flowering results, a location with full sun is ideal.
Cold Hardiness: The plant is cold-hardy and can withstand temperatures down to USDA zone 8b. In colder zones, some protection may be needed during unusually frosty periods.
Water Requirements: Once established, the Simpson Stopper is notably drought-tolerant. While young plants will benefit from regular watering, mature plants can manage with occasional watering during extended dry spells.
Fertilizing Guide: Fertilize Simpson Stopper in the spring using a balanced slow-release fertilizer. This will encourage healthy growth and prolific flowering. It's always a good idea to follow the manufacturer's recommendations when applying fertilizer to prevent over-fertilizing, which can harm the plant.
Planting Guide: Choose a location that satisfies the plant's sun requirements and offers well-draining soil. Dig a hole that's twice as wide as the plant's root ball but not deeper. Gently remove the Simpson Stopper from its container and place it in the hole, ensuring that the top of the root ball is level with the soil surface. Refill the hole with soil, compacting it gently to eliminate air pockets, and water thoroughly.
USDA Zone: Simpson Stopper is best grown in USDA zones 8b-11.
The Simpson Stopper is not only a beauty in the landscape, with its fragrant white flowers and bright red berries, but it also serves as a vital source of food and shelter for wildlife. This plant's resilience to pests, adaptability to various soils, and moderate water needs make it an excellent choice for those looking to create a low-maintenance, wildlife-friendly garden.
